    I wonder how long it takes, and will there be an improvement in how quickly it can be done now that they've had the practice?

    Aren't they all due to be done by next August. At that rate they'll need to do 2 a month

    The actual operation only takes a few hours, but clearly there was a teething problem with 5021, whether this was a persistent difficulty, or a dispute between Transdev and Alstom as to who was at fault, I do not know.

    Hopefully the remaining trams can be extended without difficulty.

    First tram of that type which Alstom have ever extended to such length, so teething issues are inevitable since the new ones that were delivered were always designed to be that length and the other parts of the tram took that into mind whereas the earlier ones were not with this in mind.

    Do we know if it was just a trivial issue with design or a power issue? I seem to recall that when the 55m trams were first introduced there were a number of failures attributed to the motors?


  • Registered Users Posts: 4,124 ✭✭✭goingnowhere


    Issue on the 55m was an intermittent issue with the static inverter.

    5021 is out in service today, seen here on Marlborough Street (apologies for the not so stellar photo, it took me by suprise!)

    5014 was extended last week.

    Any record of how many of those 26 are extended up to date?


  • Registered Users Posts: 17,833 ✭✭✭✭Idbatterim


    At peak times. Could they not turn certain trams back at ssg?

    Why?

    They do via Parnell. Turning at SSG would just disrupt the high freq over peak times.

    5021, 5001, 5014. Three to date.

    because a huge amount get on / off at SSG... How long does it take to get a tram from SSG to do the loop and get back there again? at least 12 minutes?

    youd have less trams crossing OCB at peak times, which would help other traffic...

    And a huge amount get on/off at Dawson, Trinity etc.

    say you can get a tram to SSG, the next one in several minutes goes direct to dawson, who is going to wait another few mins for a few second walk? before this there was a ten minute walk minimum to connect on the different lines.

    the city centre bit is so glacial! Im interested to see what happens when all the new extended tram capacity comes online and is full again, how they go about increasing capacity!

    MOD: Yes, thread title updated.

    Saw a 55 tram on O Connell Street at lunch time. Seamed to stop at every traffic light including where there was a green phase for general motor traffic. Seems very inefficient!

    If trams are overcrowded why can't people at SSG wait a few minutes for next one?

    Turning at SSG will case a backlog either using the older turn back or new one.

    You are right once all trams are longer there will be problems, no taxi ban, no enforcement of traffic laws and to many signal failures these days.

    Trams obey signals not the lights; though there could still be a problem with the signals obviously.

    I think this is exactly what alentejo is saying.

    Had an occasion to travel 5014 yesterday - no number on the cab but I figured out it's a long one after pantograph located in the middle of the tram (5 wheeled sections). Number 5014 was labeled inside, and it also didn't make strange noises as in the middle section in 5021 did when I traveled it some time ago.

    The objective of the exercise is not necessarily to move the tram through as fast as possible. The operator may be trying to keep even spacing between trams in order to maximize capacity.

    O'Connell St is not a good example of tram priority as there are several modes including a perpendicular tram line

    5018 is now extended to 55m


  • Registered Users Posts: 1,943 ✭✭✭tabbey


    5002 has been extended to nine module / 55 metre.


  • Registered Users Posts: 1,943 ✭✭✭tabbey


    The programme of extension has speeded up, the ninth pair of additional modules arrived in Sandyford this afternoon, less than two weeks since the eighth pair.
    5008 has been in service the last couple of weeks, maybe more.

    Is it like luas upgrade is limited by delivery of new modules from Alstom? Are they delivered from France or someone else makes them? It is great to see more and more long trams coming on platforms in Dublin.

    THE luas is an unreliable Mickey Mouse piece of infrastructure, already past it’s sell by date !

    In a city of one and a half million , we have the luas , servicing the most central areas and it runs On street at a glacial pace, has significantly impacted on the bus network and doesn’t even have priority at some minor junctions, for what can shift about what ? 500 per tram?

    It cannot handle the numbers Using it now at leak times , never mind another few years from now with the huge scale of development in Dublin ...
