New Dublin Rail Lines on Google Earth

mackerski

Folks,

** Further Edit: overlay updated to V5, now with bugfixes, Luas and speculative Metro West **

To assist in visualising the new proposed transport network, I've begun on a Google Earth overlay to show the new lines and stations. So far it's restricted to the central area DART lines, but let's hope I (or others) can develop it to include Metro and Luas proposals too.

The line colours are invented, so any suggestions for more appropriate ones are welcome. Similarly, I've just used generic "D" icons for DART stations - some custom icons would probably be better.

Comments?

I'm new to Google Earth, so bear with me-how do you get rid of all the non-transport stuff?

Depends which stuff you mean - Roads can be switched off from the control panel under the map display, any other stuff it might be showing you is probably under the heading of "Google Earth Community" and controllable from the lower left side. Sometimes you can't tell whether a subset of the "left side" overlays is enabled, so you might want to check and then immediately uncheck some top level items.

I can't see the yellow lines very well. Can you make them more visable?

OfflerCrocGod

Good work! It's nice looking I'm surprised at how short the lines are though.

I did say it was restricted to the central area...

But I have a lot more done in the meantime, I'll post an update soon.

Right, I've updated things considerably. I've increased the opacity of the lines, though I think there's value in allowing as much transparency so that we can still see roads and buildings along the alignments. Things are a lot easier to see if you switch off certain other overlays, particularly roads.

The Map now contains:

Kildare (even though that's not in the plan) - Balbriggan DART line via interconnector.

Maynooth-Greystones DART.

Swords Metro route based on best available intelligence of stations and alignment.

Missing (for now):

Howth branch (and whatever onward route its line is going to take, tips welcome).

Orbital Metro (this should be a big exercise in predicting the future)

Luas (present and future).

Navan Branch (anybody know the intended stations and locations?)

Most projected new stations on the Maynooth branch, except for Porterstown, whose location I've guessed. Details welcome on these.

Please help with:

Station locations. Some of them I will have got wrong, especially outside the areas of detailed coverage. Others, like Adamstown and Kishogue, I haven't got sufficient info about where they are supposed to be (but I think the information is out there).

Custom icons: anybody with an artistic flair who thinks they can get DART, Luas and Irish Rail logos looking good in a confined space is welcome to offer artwork. Anybody who can invent a plausible Metro logo, likewise.

Metro issues:

My stations and alignments were taken from this map. Some of it goes against things already announced or against my own common sense:

Dublin Airport: The station location looks too far away from the terminal. Especially in a world where a brand new terminal is to be built, this seems wrong.

Botanic Road: This is near Glasnevin Junction, but not near enough to provide useful interchange in accordance with the announcement.

Stephen's Green: The map shows the station splodge right over the east side of the park, more or less the worst place it could be for Luas interchange. For purposes of my overlay I've ignored this. In practice, depending on how deep the escalators go, the platforms could end up quite a bit east of Luas, but I've compromised a little for now.

Orbital Metro: Where to start??????

Enjoy,
Dermot

Find attached the alignment for the Pace spur as far as Dunboyne. Because of the M3 I don't know exactly where the Pace P&R will be. The location for Dunboyne station is where the old (closed) station is now, it'll be very close if not right here when reopened. I've put Hansfield station right in the middle of the SDZ. I think it'll be there, or possibly slightly to the west beside the proposed road from Ongar to J2 on the M4/N4. That's all in the FCC development plan.

The metro station at 'Botanic road' will interchange with DART at Glasnevin Jcn, so you could move that to be on the same spot and drop the botanic road name IMO.

The metro west alignment is well defined actually, but I only know parts of it 100%!

I'll attach an image with the bits I know later!

Edit: The metro alignment at the airport is a bit off. Here is the alignment as advised by the RPA to FCC. And here's where it came from. Click on the south fringe and swords maps for an accurate alignment from Ballymun to Swords.

Also, the blanchardstown map no.s 7 & 11 show what was the alignment reserved for a DART spur to the blanch centre, but this will be subsumed by the orbital metro which will continue north over the N3.

morlan

Good job. Wish I had the Pro version too

I think the Botanic Road metro stop is actually meant to be Glasnevin. I think they've decided to build an interchange here. It would make sense, look how close together they are.

On Botanic Road, I'm assuming the same thing. I'm guessing the route map I used may be a little out of date.

It's very good.

Not that it's critical to the basic work that you're doing, but "Digital Hub"? Any chance of a more inspiring name?

This should explain where Pace is

If you on the M3 its before the Fairyhouse crossroads behind the line of trees on the left if Navan bound

I hope they do find a better name. FWIW, I'm pretty sure I've placed it wrongly anyway...

Anyhow, V3 is now reachable under the same attachment. Both Luas lines are now in place. That's my lot for today on this little project, but now that Marko has provided (thanks Marko!), I'll probably wire up as much as practical of the Navan branch and then whore around for further tips on the orbital Metro or new Luas lines.

I quite like 'Digital Hub', quite funky.

As Ireland is the chosen European country for technology companies, I think it the would be quite fitting.

I'm sure the station is supposed to be on high street.

What else should I call this street?

It's one of the oldest streets in Dublin, being in the Viking quarter, and it's one of the highest points in the city, maybe that's why it's called High Street?

jlang

murphaph is right to call the street High St, and probably the station too, as that's what the IE material released has said, but I hope that the station takes the name Christchurch when actually built.

mackerski

Contrary to my earlier post, I have made one further update. This one includes the Navan branch as far as pace along with a bit of a punt. I've speculated on an alignment for Metro West. I've tried to unify what we (think we) know about this line - stations like Porterstown, Blanch Centre, Abbotstown and the other clues from the published "map", also the fact that it's expected to be overground except from Clondalkin to Tallaght.

I've drawn this together into an alignment that simplifies Clondalking to Tallaght to a straight line, on the assumption that the whole thing will be underground. For the rest, I've sought out available space, like along the Fonthill Road and Blanchardstown Road South. Some of this is a bit hairy, mind you, it gets pretty close to some houses.

In the D15 area I wasn't happy with the alignment I ended up with when I tried to include a station you could call Abbotstown. A valid routing does seem to be available, but you end up serving a station that's not that convenient for the Aquatic Centre (which is all that there currently is near there). For that reason, I also sketched out a more northerly route, taking in Blanchardstown Corporate Park and a few of its like-minded neighbours. This alignment, along with some wild-guess stations, is the thinner line.

Anybody with knowlege of actual plans for this line, especially key stations, please let me know.

Dermot

murphaph

The alignment from Porterstown to the N3 looks spot on, I'd bet my house (which is a convenient 10mins walk from the likely location of 'Shelerin' Station as outlined in PFC!) that that is the correct alignment.

I don't think you've got it quite right north of the N3 though. PFC always made the alignment I've attached look more likely. From Abbotstown it gets ropey as the PFC envisaged a route through Finglas, but what you have is as good a guess as any.

The Google maps hybrid mode is just the ariel photography with the roads/POI's overlaid, isn't it? That's the normal display mode of Google Earth, isn't it?

I hadn't actually looked at the full details available from PFC. I have now, and it muddies the waters a bit. DTO has two somewhat conflicting maps available:

* A schematic map, giving station names.
* A geographic map, giving an alignment but no stations.

The geographic map depicts an alignment that clearly follows that part of my route that you agreed with, but it's also clear that it runs west of Blanchardstown Road North, as my alignment did, in a way that neatly brings it alongside the IT. (my reasoning here is that the grey built-up shading follows B. Road N. and the line diverges from it visibly). My mini-loop was silly, though, even in a world where Abbotstown is to be served, and I've got rid of it.

However, back to the DTO plan conflicts: If our assumptions are correct, then where can the Shelerin and Mulhuddart stations be? Either they are really badly named or the schematic is assuming a slightly more western routing, that must run mostly near the Blakestown Road - and even then, I can't see how you can go Shelerin-Blanchardstown (centre?)-Mulhuddart. Nor can I guess how you'd get from Porterstown to Shelerin.

On the basis of this, I've adapted my overlay (upload to follow this post in a few minutes). My best-guess alignment now follows the geographic DTO map as faithfully as possible having regard to obstacles and the fact that the line must now steer for Ballymun. My alternative branch is a new stab at how to serve Abbotstown - Since I work in Blanchardstown Corporate Park, I really hope that that its inclusion was a slip of the pen.

I've also doctored some of the rest of the alignment to follow DTO, though I wimped out of guessing the Clondalkin and Tallaght routing. It's too hard in the areas with no decent aerial photography. One issue does arise, though, which is that my anticipated Fonthill Road interchange station doesn't work any more, unless the DART station moves East.

Dermot

mackerski

Another new overlay, but I can no longer edit the original post. This is V6, including latest adjustments to the (guessed) Metro West route.

Dermot

murphaph

Interesting Dermot. The Shelerin and Mulhuddart names are poor(ish), I reckon the Shelerin stop is at the junction of Blanchardstown Road South and Mountview Road, could be renamed something better though-Shelerin is a townland as far as I know and nobody uses it locally. Mulhuddart isn't the wrost name for a stop there, though perhaps Mulhuddart & Corduff would be better?

I still think the alignment stays to the east of Blanchardstown Road North though because there is a clear space between the road and the houses in Corduff and the alignment was reserved under the auspices of Dublin County Council, that's probably why we see the same 'style' of roadside reservation along Blanch Road South (now Fingal) and Fonthill Road (now SDCC) - maybe not a scientific reason, but it sits well with me that the original planners would have maintaned the same type of reservation along those wide suburban roads where possible becuase every time you cross over and back the same road you are adding hugely to the cost with the bridges.

It's your baby though!

I thinkn the alignment from Clondalkin to embankment road (where the Luas crosses) will be the central reservation of Belgard Road, same as the swords btpass alignment.

spacetweek

But I don't get it... if the Metro travels alongside or down the central reservations of major roads, what about all the at-grade crossings??

I agree with you here up to a point. The reservations beside Blanch Road N will have been planned before anybody thought of putting a college in there - so just because right along the roadway is where they were once thinking of laying track doesn't mean that this plan will endure. It's actually quite a walk from the road to the college buildings, so there is a strong case for looking to run the line closer to it. Plus there's also a clear reservation that allows you to do so. In addition, it's clear from the PFC geographic map (link now fixed, both used to point to the schematic one) that their intended alignment does veer west of the road. Obviously, there's no guarantee that the new plan will stay the same, but it's the best we have to go on.

On bridges - yes, they cost money. I did try as much as possible to avoid them, but I found that, even on the Fonthill Road, there seemed to be places where there just plain wasn't enough space in places to avoid changing sides. That's down to my Google Earth manner of surveying, so in the Real World, better judgement will apply. I think, though, that getting across Blanch Road S/N may come a bit more cheaply that I'd drawn it. There'll have to be a pretty wide span on the bridge carrying the line over the N3 junction. It may be practical for the same structure to switch sides as well. (overlay now edited with this assumption).

BTW, am I alone in assuming that this stretch and any in-the-median stretches will have to be built on embankment in order to keep the bridges sensible?

I think you are dead right, and I'll alter the diagram accordingly. I got it into my head that they planned on tunnelling this stretch, which is at odds with the PFC maps. Given this, the likely terminus is on the Belgard Road just outside the Square, yes? Or maybe an elevated station in the centre grounds...

I don't think they'll put it on an embankment. It'd cause immense visual intrusion. I think some places might even get underpasses and long stretches of C&C rather than bridges to alleviate the visual intrusion. A metro is to be welcomed, but if it severs a community in two it becomes a lot less attractive. I can actually imagine the stretches along Blanch road south being C&C because they will severely restrict access to the park from Hartstown/Mountview if the whole thing runs completely at grade (it would have to be completely fenced off too, just like IE fence off heavy rail for safety reasons). Relatively speaking, C&C along these stretches is still far far cheaper than boring with a TBM. Time will tell though.

I don't think the RPA have as much vision as you Dermot. I think the terminus will be at Embankment Road! You'll have to change to Luas to complete your journey to the Square. That's what it looks like on the T21 map anyway!

It would certainly be better this way - but it'll have to climb back out (and then some) to cross the N3. Doable, though. Another advantage of burying the line is the noise reduction. On either of the alignments (along road or detouring west) alongside Blanch Road North, trains on the surface or an embankment would be close enough to houses to be annoying. I'm not sure the price is right, though.

Dermot

murphaph

Certain parts of the alignment could be put underground and residential built atop. Car independent housing (no parking spaces!) used to finance the C&C sections, might work along certain stretches like Coolmine IMO.

Bill McH

Looking again at this good piece of work.

I know it's all got to be worked out about the exact route of the metro, but the Google Earth images here show the metro north line travelling under houses/offices between O'Connell Street and the Royal Canal.

Given that a lot of these (e.g. on Great Denmark Street) would be protected structures, would it not be more likely that there would be a very considerable amount of tunnelling under the streets, i.e., Parnell Square, North Fred, Blessington Street, Berkeley Street, Berkeley Road to the canal.

(Also wondering how wise it is to build a tunnel directly under a prison - I mean, might it not conflict with (or assist) other tunnels under construction.:)

All fair points. You'll have noticed that my indicated alignment on this stretch i composed largely of cop-out straight lines. It's clear that I'm way off and I didn't even consider an actual routing, since I was speculating wildly even on the station locations. Going under streets seems likely to be the preferred option, though street corners will need to be cut. A lot of the street routing you mention does indeed look likely, and may imply a Mater stop closer to Berkeley Road than in my version.

How things continue from there is less clear - I included a Botanic Road station that I lifted from one of the maps posted here, but that conflicts with the more likely (and announced) Glasnevin Junction station. This points to a more westerly route that will probably go under some housing and even the cemetery (I wonder how folks will feel about that). Then follow the single-carriageway part of Ballymun road, surfacing in the median once it goes dual.

Bill McH

Thanks for that, Dermot. I've no idea how you do the overlay, but I take your point that it's difficult to pinpoint or illustrate an exact route with so little information. It just struck me that we would be running into difficulties if tunnelling directly under old buildings like those on Gt. Denmark Street. I don't know if they are protected, but I'd be surprised if they weren't.

Perhaps the Mater Hospital stop might be under the park which is beside Berkeley Road Church and directly in front of the old part of the Mater Hospital? It certainly doesn't look like it would be difficult to reinstate it after construction, as it's really just a nice lawn with a couple of trees.

The obvious flaw with that location is that it would be a good bit closer to Glasnevin Junction than to the proposed station on O'Connell St.

Victor

mackerski, I corrected your correction.

But the prison is to be sold .....

I suspect Coláiste Caomhín (Mobhi Road, Dept of Defence) will have a similar fate.

flogen

Brilliant stuff, thanks a lot.
I'm currently residing in the UK at the moment and only heard about the full proposals recently, the Sunday Business Post had a pretty poor diagram of how the new tracks would look, this is perfect though.
I've missed so much, at what points will the metro be underground and when will it be overground, or is it all under now?
Also, what's the Metropark thing to the north of the North Ballymun stop? Is it what it says and a place where the Metros will park at night?!

Oh, and what of the Luas interconnecter? Will that just be the metro line running from stephens green? I thought it would be an actual luas extension.

Thanks again

Victor

It's also called "Northpoint". Its merely the area between the airport, Santry and Ballymun. Harristown isn't quite as sexy.

Ah, silly me, I'd forgotten that. So not unlikely that the metro might indeed go under where the prison currently is.

Winters

Metropark is the location of a large proposed mixed use development, park & ride and also the Metro north rail depot.

Dermot, the Metro West will actually cross the Liffey alongside the M50 road bridges. Rename your 'Liffey Valley' stop to 'Coldcut' and bend the metro west under the SC and then out to the road bridge. There will be a stop under the SC titled 'Liffey Valley' with connection to the Luas Lucan.

The route will then run alongside Carpenterstown Road to Porterstown Road.

The south end of the metro west will currently terminate where the Luas crosses the Belgard Road. (Depot situated off Belgard Road near the Naas Road)

The metro west will indeed cross the Kildare line at Fonthill Road and continue alongside the Fontill Road through Clondalkin to the Belgard Road. It is currently planned to have this section elevated. In fact the RPA would elevate it all given half the chance.

The metro north will actually extend all the way north to the Lissenhall interchange (Where the Swords Bypass meets the M1!)
where there will be a large Park & Ride.

Well done indeed, there's also Lucan, Docklands, Citywest and Bray Luas.

PS theres no station between Fonthill Road and Parkwest.

Victor

That sounds very authoritive.

Winters

Oops, sorry i didnt mean for it to be. Let me know how its done and ill do it myself.

murphaph

I think Victor meant that it sounds like you've got a good source for that alignment info!

Is it definately gonna run under the LVSC? Elevated through Clondalkin?:eek: I thought it was gonna be in a tunnel under the village?!

wwhyte

Glad to hear it'll be going under the Liffey Valley SC. It'd be useless to have it stop on the road outside and make people take shuttle buses or something.

How do you know all this, btw?

murphaph wrote:

The old Platform For Change docs showed it underground in Clondalkin. Surely elevation would be too visually disruptive.

Off topic: I've been trying to figure out for ages what route the Lucan Luas could possibly take. AFAICS no reservation for it has been allowed so it will have to go on-street. Where could it terminate? PFC listed a stop in Esker so I thought maybe it would head on-street out that way, over the N4 on a bridge and then up through Vesey Park, hitting the Newcastle road about halfway between the N4 and lucan village. But what then? The Newcastle road at this point looks like a country lane. Not really a suitable terminus.

I'm not sure I have you right here - my speculative alignment is already well west of the SC. And if the river crossing is close to the M50, the Carpenterstown Road can't be the onward route - To be clear, the Carpenterstown Road starts at Castleknock College, veers right at the fork for Porterstown, crosses the M50 and then enters dense suburbia. I can't see a rail alignment here when there's an easy greenfield option.

This all seems possible - my original stab at this stayed alongside the Fonthill Road. I changed it based on a (small) map and informed discussion of a tunnel under Clondalkin. Our real problem here is that there are too many proposals in the wild. How solid are your facts compared to the others?

No real need for one if the DART crossing is indeed at Fonthill Road.

The N4 is dual-carriageway all the way out, so you can imagine a lot of it running in the median.

Dermot

Victor

In some places the median doesn't really exist.

I think somebody just screwed up and didn't realise it was to branch off the red line as in PFC.

Winters

Sorry Mackerski, I miss worded that and got Luttrellstown Road mixed up with Carpenterstown Road.

The Metro west will turn EAST from Coldcut and pass under (probably cut and cover) the SC and emerge to cross the N4 and run between the Kings Hos school and the M50. It will then cross the Liffey alongside the road bridge till it hits the current site of the toll plaza where it will turn west and run alongside Luttrellstown Road and turn north at the Porterstown Road to run east of that along its duration to Blanchardstown Town Centre.

If the Lucan Luas uses the original PFC route it will branch off the red line between Kylemore and Bluebell and run along the Kylemore Road to the Ballyfermot Road with a connection to the DART as it crosses the rail line at Landan Road. It will run the length of Ballyfermot Road turning off at Coldcut road to cross the M50 and turn into Liffey Valley SC to connect with Metro west. It will then cross the Fonthill Road and run along St. Lomans Road and then Ballyowen Road accross the N4 (Lucan Bypass). From there I dont know although more than likely it'll reach Liffey Valley SC before its extended to Lucan if at all. Primarily street running for most of its duration.

Like I said above, the RPA would elevate the whole thing if they could because its cheaper then cut and cover or tunnelling. Thats the reason why Clondalkin looks set for elevated running.

Nothing is certain yet, these are just some of the current favoured RPA route options as outlined by them at a presentation on 17th Jan in the Spa Hotel, Lucan.
