    I was in the Glassbottle site this week. The way the units are going up there they could do with building a luas extension very quickly from the city center



  • Registered Users, Registered Users 2 Posts: 161 ✭✭OisinCooke


    Agreed, I’ve seen the development myself from afar and they really are flying up. Ideally the Lucan Line will run through the south city core and continue on to serve Ringsend and Poolbeg and all the development which is exponentially going up there. However a Red Line link from The Point in addition would be great, meaning that with a direct Red Line and Lucan Line link at both James’ and Ringsend, a lot more flexibility is opened up for tram diversions and even (although to be honest I don’t personally think this is a great idea, it will look appealing to the pen pushers and the public as being similar to many other successful urban transport systems) allows for the possibility of a Luas ‘Circle Line’ around the city centre.

    If luas lucan extends to Poolbeg, I think it would already have a connection with the red line after its extended to Poolbeg? I think it is a lot more feasible than having them interchange at the point, as the area where the Poolbeg red line station is has plenty of space to expand. If needed they could even make the station 6 platforms as a double 3-platform terminus.

    The circle line is an interesting idea, I don't think much can be said about feasibility yet as I think both Lucan and Poolbeg have a number of very different routes to decide from. Mainly it seems there is both an option for the Poolbeg extension to terminate either facing north or south on Sean Moore road, and it would make more sense to make a circle line if they chose the route that terminates facing north. That said I think having the two lines stay as separated as possible and having people interchange at Poolbeg or the western interchange would offer a more frequent service.

    Will the red line and Lucan line not be a bit close for you to be branding them a circle line? Though there might not be a viable route further south.

    I was looking at the Poolbeg extension and thinking it would be crazy not to extend it to meet the Dart but I just can't see a viable route

    It depends on the final allignment. The circle line would be best if they pick the Grand Canal route, though I still think it would be possible with the Cork street route if its routed through SSG. Any allignment further north, so the Heuston route, or if they routed the Cork street option through College Green, I think would be too close to the red line for a circle line.



  • Registered Users, Registered Users 2 Posts: 285 ✭✭PlatformNine


    I think the DART connections could be made as a part of Luas Lucan. The idea I had was if it followed the Cork street-SSG route option, instead of terminating at SSG, it could be extended to Poolbeg and routed to have an interchange with Pearse and/or GCD. The stops likely couldn't be placed too close to the DART stations, but I think it would be comparable to Busaras and Connolly.

    Eitherway, I don't think Luas Lucan should terminate at Heuston or SSG, I think it makes more sense to continue through CC, and terminate anywhere else, though I think Poolbeg is the best option.



  • Moderators, Science, Health & Environment Moderators Posts: 5,339 Mod ✭✭✭✭spacetweek


    Totally agree about Lucan Luas continuing past Stephens Green, but I think it should go Leeson St to Wilton Terrace to Clanwilliam Place (for Grand canal Dock).

    For the Stephens Green South stop, you’d have to decide whether you intended it to be South west to serve Luas Green line or south east to be closer to Metrolink.



  • Registered Users, Registered Users 2 Posts: 75 ✭✭roddney


    Hard if it turns right at O2 Arena and heads to Poolbeg alright. Easy if it turns left and heads via side of Dublin Port to back of Eastpoint Business Park and on to Clontarf Dart Stations. Would make a good future Malahide Road Luas. Also, options to run either via Dublin Port and a bridge or tunnel via Vernon Ave in Clontarf and Brookwood Ave to Dart at Harmonstown with new entrance on Brookwood. Would allow up Malahide Road without disrupting new Bus Connects Bus lanes.



  • Registered Users, Registered Users 2 Posts: 161 ✭✭OisinCooke


    Ideally, a Dame Street route could have a Tara Street and Pearse (Sandwich Street) stop for a direct DART, DART tunnel and ML link but we’re yet to see whether or not they want to route it down Cork St or Dame Street. For me the canals is an awful option, much too far out from the city centre and there is not much road capacity for it.

    Also a very good point. I suppose the idea was more just that you’d be able to get between all the city stations via the one tram than specifically a circle line. However I do think that the Lucan Line (whatever route it takes) should be operated in the city centre much like the Red Line with a cord of track provided to link trains heading from the CC towards Lucan with Heuston. The way I see this working would be to extend Heuston’s currently terminating turnback platform to be a through-turnback. The current Connolly-Heuston services could then be extended to SSG/College Green/Tara/Poolbeg/wherever and could act as a shuttle from virtually anywhere in the city centre to Heuston without taking much capacity off the trams going out of the city to Lucan, in the exact same way that the Red Line currently works. Just an idea I suppose but could prove useful…?

    To tie in with the red line at the point would the luas have to be battery powered for crossing the liffey?

    I am not sure how over head cables would work on a lifting bridge for the luas to cross the liffey. I am sure it could be done but it would not be cheap.



  • Registered Users, Registered Users 2 Posts: 72,824 ✭✭✭✭L1011


    I'm absolutely certain there's various lift bridges in the Netherlands, rail and metro with OHLE. However Google has been enshittified so much now I'm getting kids toys and AI 'art'works instead of actual content.



  • Moderators, Motoring & Transport Moderators, Technology & Internet Moderators Posts: 23,642 Mod ✭✭✭✭bk


    So true, but apparently the Dutch think who needs cables if you just YOLO the train across the bridge LOL:

    Obviously that won't work for this crossing, apparently there is an example for trains in Norwich, they use a rigid bar over the bridge which is separated from the usual wire on either side:

    https://www.geograph.org.uk/photo/1675740

    You could also just put a small battery on the Luas trams, just enough to cross the bridge. It could even be part of an upgrade with a hybrid system for regenerative breaking to reduce power usage.



  • Registered Users, Registered Users 2 Posts: 285 ✭✭PlatformNine


    I think it would be possible to route it both down Cork street and Dame street, as I think the only other way to get it to Dame street would be via James street. Though I don't know if they could use Patrick street, the gradient might be too steep. However what concerns me is if they were to route to Dame street, they would likely need to route through college green, and I am not sure how they could do that without either congesting college green or tearing it up for a cut and cover. I don't think having it cross at st stephens green is much better, as it would also require some separate grading. However it would require less disruption than at college green, and might become necessary anyways to avoid congestian with the F-spine.

    It might, I think it entirely depends on if there is room to add services for that without reducing frequency of red line and Lucan line services.



  • Registered Users, Registered Users 2 Posts: 285 ✭✭PlatformNine


    If looking at the battery route, how large of a battery would be needed? The moveable section is only about 50m? At what point is it cheaper to just electrify the section of bridge than installing batteries in the red line fleet?



  • Registered Users, Registered Users 2 Posts: 755 ✭✭✭loco_scolo


    I don't ever see a Luas crossing College Green, from Dame Street, as I think the disruption could not be justified, both during construction and when operating. The front of Trinity will have the Luas Cross City and the A / E / F Core Bus Corridors, while the side of Trinity will have the Luas Cross City and the B / C Core Bus Corridors.

    Adding another busy tram route into that mix would negate the whole point of closing off College Green, and creating a pedestrian plaza, in the first place... which is to minimize conflicts.

    However, I still think a spur from James down to College Green (terminating there) would have merit. That spur could potentially operate from Heuston West even, or by having some Red Lines services terminate there, hence freeing up capacity on the Red Line north of the river.



  • Moderators, Motoring & Transport Moderators, Technology & Internet Moderators Posts: 23,642 Mod ✭✭✭✭bk


    Relatively very small batteries to cover that small distance. Shouldn't pose any problems in terms of weight, space, etc.



  • Registered Users, Registered Users 2 Posts: 12,057 ✭✭✭✭tom1ie


    If you take a look at the pinch points on the red line one by one can we do anything about them without lengthy closures of the line?
    For example look at the Belgard road crossing- could new Luas track be laid on the north side of Katherine Tynan road temporarily to keep the line open which would allow a bridge be built over the Belgard road and old Belgard road in the current alignment.
    The station would also have to be moved temporarily further to the west.



  • Registered Users, Registered Users 2 Posts: 15,612 ✭✭✭✭loyatemu


    the red line's priority through the city centre section is terrible. I know some of the roads it crosses are also major bus routes but anytime I get it, it spends a lot of time sitting at junctions where there are just private cars going past (bottom of Gardiner Street springs to mind).

    Some form of intelligent signalling at these junctions would probably go a long way to speeding it up without having to dig anything up. It should have absolute priority if there are no buses crossing, and if there are buses crossing there could be some sort of algorithm to decide who gets priority.

    Are we maxed out on the frequency and length of the trams on the red line?



  • Registered Users, Registered Users 2 Posts: 285 ✭✭PlatformNine


    I completely agree my point was more that it likely couldn't go down Dame street as part of Luas Lucan, as it would be better to terminate the line further away from CC. Or like you say, it would have to be a spur, not the main terminus.



  • Registered Users, Registered Users 2 Posts: 12,057 ✭✭✭✭tom1ie


    I would imagine it will be a no brainer to extend the red line at the point:

    down east wall road

    across the liffey on a new bridge

    over to the glass bottle site where 3800 new units are going to be constructed.



  • Registered Users, Registered Users 2 Posts: 14,100 ✭✭✭✭Zebra3


    No brainer or not, everything moves at snail’s pace….



  • Registered Users, Registered Users 2 Posts: 2,436 ✭✭✭KrisW1001


    Slated for “before 2042".

  • Registered Users, Registered Users 2 Posts: 12,057 ✭✭✭✭tom1ie


    Christ!
    At that stage all residents will be in at least 12 years!



  • Registered Users, Registered Users 2 Posts: 2,436 ✭✭✭KrisW1001


    Doesn’t mean it won’t be done until 2042. Luas Finglas is in the same category on that map. I see Poolbeg Red and the Bray Green extensions being the next projects once Finglas gets its RO. As the shorter project, Poolbeg could be before Bray.



  • Registered Users, Registered Users 2 Posts: 12,057 ✭✭✭✭tom1ie


    Yeah but they all go into the same pinch point that is ABP.

    That particular department is absolutely killing this country.



  • Registered Users, Registered Users 2 Posts: 10,015 ✭✭✭✭cgcsb


    Metrolink will pass its 2nd birthday with ABP soon. TII have even complied with ABPs vexatious demand for additional public consultation. Even if the RO is granted very soon, we'll still be having 2 years of legal challenges from Charlemont residents. This doesn't bode well for new infrastructure. The current metrolink project is now unlikely to break ground within a decade of the project commencement date.

    We were able to get big projects to construction much quicker 20 years ago. It seems we've deliberately tied ourselves up in red tape.

    I recently read the ABP inspectors report on the DART+ W RO, thankfully the board over ruled him on most items.

    Objections included:

    Heritage bridges like Cope bridge should not be changed at all....ever

    Construction noise, seemingly any type or volume isn't to be tolerated

    The depot should be in an urban area accessible by public transport, but should also be big enough to stable trains and not be at risk from flooding.

    It's as if we're employing people to adjudicate on these matters who:

    a) know nothing at all about railways and how they operate or are constructed, and

    b) who have absolute, unshakeable, confidence in their uneducated opinion, to the point that they wouldn't even ask someone or consult the near sum of human knowledge available for free via the Internet.

    The whole thing needs a clear out, people who haven't an effing breeze what they're scuttering on about need to be put on some tasks more suited to their skills and hire actual experts to scrutinise applications instead.

    Just about on topic, as it is probably related to some future plan for Luas, but the arrangement (below) always puzzles me when I pass it. This is where the southbound Green Line crosses Red Line - I’ve drawn the directions of the trams on the image for reference. So: what purpose can the chord in yellow ever serve?

    image.png

    It could see it making sense if Marlborough St originally was supposed to run Northbound, as it would then have allowed for a Connolly to St Stephen’s Green Luas service. (Of course, the O’Connell St Northbound to Abbey St Westbound track link would then make no sense.)

    Note that the only points anywhere near here are the trailing points shown here (Red East to Red West) which allowed Red Line trams to turn back after the Abbey St stop on the original Luas Line A, which terminated at Abbey St. If there was an opposite set of leading points (i.e. Red West crossing over to Red East briefly), then I could see the whole thing as a way of making a right turn from Red West to Green South work in limited space, but there isn’t.

    Can anyone shed any light on this?
