Dublin - Metrolink (Swords to Charlemont only)

marno21

As the other thread is reaching its limit of 10,000 posts, and in light of the announcement of the preferred route, this is the new thread for discussing the Metrolink scheme.

Old thread here: https://www.boards.ie/vbulletin/showthread.php?t=2055849587

This is for discussing the current active plan for a Metro between Swords and Charlemont. Only. Discussion of the planned Metro South connection to the Green Line will be in this thread:

Out of interest, I measured Eamon Ryan's suggested route ("keeping the TBM going") of continuing on via UCD and then on to Sandyford. It's about 7.5 k. That would be another 90 weeks or so of tunelling (ie pushing the time out when services could start ruinning by nearly 2 years)

Depending on what direction it goes I presume they could route it via open ground which would allow a new opening to remove spoil and not have to send it all back to Northwood.

They could, maybe use Donnybrook Bus Garage (which at least has access to a good road for trucks of spoil). I doubt the locals would be happy with that either!

Doesn't look like it from that angle, but they've already acknowledged that Charlemont is the station most likely to change, so hopefully the final design isn't as bad there.

There's a Luas turnback facility to be added at Charlemont - I'm guessing one extra platform. Maybe that extra platform could be closer to the Metro station, instead of alongside the existing platforms. Possibly on the alignment of the defunct EPR tie-in.

Ideally you'd get off a terminating Luas and get on an escalator that led straight down into the Metro station.

Seems to be that locals are never happy when it comes to new infrastructure or housing in their area these days.

It would also be great if the OCS station was also accessible from Parnell Street which would make it easier to get to the Rotunda, DIT Bolton Street, future city library, etc. This can easily be facilitated by having a pedestrian route through the new development to Moore Lane.

Won’t DIT Bolton street be be long closed as it’ll be moved to GrangeGornan

Bolton Street hasn't got a moving date yet - the only current campus without one - and based on being "relatively" nearby Grangegorman I could easily see it not moving at all; or otherwise being reused.

I understand that current plans see Bolton St being retained indefinitely.

Yeah, rumour was that it was a protected structure so any redevelopment plans for potential buyers were limited by what they can/can't do....meaning interest in the site was a lot smaller than the other city centre locations.

Edit: Number 836 on the list of protected structures

8,691 protected structures :eek::eek:

I knew Dublin City Council was anti-development but that is ridiculous.

You can have lots of protected structures and still be pro-development.

Exactly. Development isn’t just demolishing everything in sight, it’s changing the use of existing buildings too.

Seems excessive in a City with only a handful of neo classic buildings and rows of Georgian houses. I'm not even sure why georgian houses are considered to be of such merit anyway. but I suppose that's subjective.

Anyway we can keep Georgian Dublin intact and build modernity in parallel, the notion that modernity should be visible at all needs to be firmly binned, we have to live and work somewhere in 2019 and there'll be 3 million people + visitors in the later half of the century.

The more I read of the new emerging preferred route, the more uneasy I'm getting. Any future link-up south of Beechwood is going to be massively disruptive and hugely expensive - getting a TBM into the ground for 2 or 3km of tunnel + cost of mining out a station in Ranelagh. The entire CBA is going to struggle.

I've looked again at the suggestions for the tunnel to emerge _north_ of Charlemont and actually I'm not sure it's impossible. Here are two options:

If the underground section emerges to street level _just_ south of Adelaide road and terminates there for the moment, then the future link can occur without any further tunnelling and the existing Charlemont and Ranelagh stations can be upgraded relatively cheaply - no more expensively than other stations - and with fairly minimal disruption. No TBM and no digging out underground stations would knock 300 to 500m off the overall bill.

The gradients will be steep but within range of metro systems globally (4-5% gradient) and operationally having the gradient descending from the future metro stop at Charlemont metro bridge is a good thing as it provides braking for southbound metros coming to a stop at Charlemont and free acceleration for northbound metros leaving Charlemont.

It would require some CPOs to buy out some of the buildings there but that's about it - even being generous you're talking about 10m or so max.

The Church on Adelaide Road is on the protected structures list, not much chance of that changing either.

They're also not going to do any further digging when it comes time to do the tie in. They'll commission a report to look at all the options, and the one that'll come out on top will be to do the tie in right where the tunnel currently ends.

Sam Russell

Irish times article

Luas closure would have lasted 2½ years
Luas green line closures could have been staged over four years to facilitate Metrolink

This 14-week saving could be achieved because the tunnel boring machine would be left in the ground from the first phase, the entire works phase would be shorter and the commissioning and running of trials would take less time, the report said.

How do you restart the TBM that has been left in the ground for twenty years? Where does the spoil go? Has anyone thought this stuff through?

The Metrolink will run on 1500 v instead of 750 v, so the O/H wires and power stations will need reworking. The platforms will need raising and probably passenger doors installed because of the high floor units and the automated trains. Yea, but not taking two and a half years.

I got a leaflet in from Jim O'Callaghan TD about Metrolink. He favours the ML going SW Rathgar, Terenure, Templeogue, and Firhouse to reduce the impact of BusConnects. Obviously trying to gather a few more NIMBY voters to his cause. He does not say where the extra billions will come from.

I think the NTA need a few submissions to draw the attention to some of this stuff.

Yes the church could be problematic but not insurmountable. That's why the more westerly route which would only require getting rid of a currently derelict house should be also considered although the required cut 'n cover might be tricky in that narrowish alley.

Your suggestion was part of the original emerging preferred route but I believe it is no longer considered feasible because the tunnel will be quite deep on the south side of the canal to avoid the sewer. I don't know how deep exactly but even optimistically, given gradient limits, you'll need at least 300m to get to the level of the existing line which will mean severing Dartmouth Road and probably Northbrook road - and the loss of a lot of back gardens and CPO of some newer houses on Northbrook Av.

If your suggestion is possible then I think it'd also be a reasonable solution. Certainly better than the idea of doing a tie-in south of Beechwood.

TII have tendered for utility investigation along the planned route

They're only investigating to Ranelagh Luas stop.

It's very frustrating that they would "postpone" the Green Line upgrade and not have whether it happens or not subject to this public consultation. I'm going to putting in that an "off-line" solution that would reduce disruption to the Green Line should be put forward, not this tunnel portal under the Green Line tracks shenanigans.

A guy from TII said to me that it was either just do the northern section or risk sinking the whole project. So I suppose it is still better than still taking here in 20 years time about the northern section.

Yeah that's how it looks alright. It'll be amazing as a proof of concept, like the system looks amazing and will lead to more Metros definitely, similar to how people said the luas would be bad and now everyone wants a luas.

It's just a pity we know what the right thing to do is, and for once money isn't a problem, but we're not doing it because 'reasons'.

[Off-topic]
[Edit:] Perhaps that is unfair. Ballymun was seen as fantastic when it was built. It had good facilities, including caretakers to keep the place tidy and well regulated. This worked very well, until the council had a cost cutting exercise which got rid of the caretakers. This caused the place to become unkempt and then antisocial behaviour started.

This caused the 'better' families to move out, and disruptive tenants from other schemes to be moved in. The decline set in until the blocks were demolished. So to save a few bob, the caretakers were got rid of, resulting in the whole scheme being demolished, and now we have no social housing and a housing crisis.

To be fair, I think we mean two separate entrances with ticket barriers etc on both sides of the road. Not just a random underpass free for anyone to loiter in.

Re Glasnevin Station & the impact that this will have on Drumcondra Station

This is going to become a major interchange on the metro line, connecting Metro with commuter rail (future dart lines) and Bus Connects. It would be great if some intercity trains from Galway/Limerick/Waterford/Cork were terminated in Glasnevin to allow for direct access to the Metro and onto the Airport. Although i suspect capacity at the station would be an issue and make this unlikely.

But my question is really about the impact that Glasnevin will have on Drumcondra Station. The two stations will be 1km apart, is it likely that they will keep Drumcondra open?

cgcsb

Glasnevin would be a great terminus point for Sligo trains and would relieve Connolloy's capacity issues, there's a bit of room at Glasnevin where an intercity platform could be installed. This could even mean more frequent trains to Sligo as the Connolly capacity constraint wouldn't be there.

I don't see why not, there are Dart stations that are closer together than 1km.

Keep it open, but only use it for stopping electric trains, so a future Maynooth DART type service. Probably not worth having Sligo trains stopping here with Glasnevin so close.

It would also be nice to build a new station at Ballybough Road/North Strand in future for Maynooth DARTs if this ever happened, would be of great benefit to that area.

1km is a fair distance for an area so close to the city centre, I can't imagine them even contemplating the idea of closing them.

I'd actually like them to put in another station at Ballybough Rd, or at North Strand. It'd be crazy to have a mass transit line going through all these areas without any station.
