[13-07-19] No green line luas services

markpb · 13-07-2019 9:59am #1

It sounds pretty serious. The last line is hilarious.

Please be advised that there is no service running on the whole Luas Green Line (Bridesglen to Broombridge) for the moment and until further notice.

This is due to a technical fault.

Luas maintenance staff are working to fix a technical fault on the Green Line overhead power lines.

This fault became apparent overnight when trams were undergoing their regular inspection.

Some tram pantographs were slightly damaged on inspection indicating an issue with the overhead power line.

The pantograph is the device on the top of the tram that connects the electrical power from the overhead lines to the tram.

Technicians are working to identify where the fault is. It is not possible to operate a tram service on the Green Line until the technicians identify what and where the problem is.

To operate trams in the affected area could result in significant damage to the overhead lines resulting in significantly extended downtime.

Luas tickets are valid on Dublin Bus.

In addition to Dublin Bus, a limited alternative bus will operate between Bridesglen and Stillorgan. Customers should note they will need to exit this bus at Sandyford for onward travel Northbound by Dublin Bus.

We want to thank all customers for their patience and apologise for this inconvenience.

Please check www.luas.ie, www.aaroadwatch.ie or follow us on Twitter for regular updates.

Please see dublinbus.ie for assistance or https://www.transportforireland.ie/ for planning your trip.

Luas Red Line is operating normally.

All lifts and escalators are in full working order.

Update:

Please be advised that there is a limited service operating between Broombridge and Dawson. 15 minute frequency between Broombridge and Dawson in both directions. No service between SSG and Brides Glen.

They learned no lessons from their control center going down then I see, still no backups :rolleyes: or emergency plans

Were so lucky were neutral and don't get involved in things that can bring terrorist attacks on us, our CIP is sh1t, you could easily paralyze this entire country by hitting a few week spots.

I'm not sure what backup you could have for an overhead line failure.

markpb · 13-07-2019 11:13am

More details on the bus:

the alternative bus is picking up passengers at all affected stops between Brides Glen and Stillorgan except Laughanstown. Frequency of the buses is 15-20 minutes depending on the road traffic

I'm not suggesting like a second set of lines or anything I'm wondering why you'd not have spare parts and an on-standby team for such things.

I'm quite prepared to be corrected but the fact that this is gonna last all day suggests they are either waiting for new parts or personnel or it's a fault that takes a long time to fix.

I could be (and hope) I'm wrong and that ti's just a case of some kinda cascade going down the lines and they need to fix it section by section.

I worry about how vulnerable such points are in this country were very easily disrupted

The biggest delay so far has been the fact that they knew the OHLE was broken from the tram damage but that didn't tell them which part of the OHLE was affected. I'm reasonably sure they have spare parts for commonly affected components.

markpb · 13-07-2019 12:42pm

Another update. Bad news:

Due to the nature of the fault we do not expect services to resume this afternoon or into early evening

Stephen15 · 13-07-2019 12:58pm

Lucky it's happened on a Saturday in the middle of July and not a Monday morning in the middle of November. Hopefully it gets fixed asap.

So the time consumption is in searching for it?
Is there not computer software to assist them with this? I know they have software for signaling and whatnot does it not have errors in the overlines pop up on a map?

L1011 · 13-07-2019 1:53pm

Physical damage that is still carrying current successfully is not going to show on a software test

Full line (incl depots) inspection probably required.

Some improvement

Services are operating from Broombridge-Sandyford. Please expect delays of 20+ minutes as service returns to normal. Please note there is no service operating between Brides Glen and Sandyford.

markpb · 13-07-2019 5:23pm

Back to normal:

Services are now operating all stops. Please expect minor delays as service returns to normal. We would like to thank our passengers for your patience as we worked to resolve the earlier fault. Thank you and apologies for any and all inconvenience caused today.

Shocking the vandalism and anti social behaviour on that line causing all that disruption.

Was tongue in cheek comparing it to the so called Dreaded Red Line.

Yeah the constant gunfire and having to wear flakjackets gets tiresome...

Funnily enough, Luas themselves, consider the Green Line worse for anti-social behavior than the Red Line.

I would agree south of Central Park in places have problems.

They were being politely vague. The problems are at Leopardstown Valley and Ballyogan Wood.

You are 100% correct. This is exactly what caused the several day outage when a tram caught a tree in Ranelagh and the driver continued on his merry way to Charlemont, damaging the line between thew two stops.

goingnowhere · 15-07-2019 11:29am

They needed to perform a visual inspection of the entire system to locate the fault, it appears the issue was located beyond Carrickmines. Luas doesn't have the fancy optical tech used on high speed lines to perform this testing.

They correctly acted when they found a number of chipped pantographs which suggests a damaged part of the OHLE, much much easier to inspect and fix than wait for the OHLE to come down.

With respect to the Ranelagh incident the tram would have been at up 70-80kph so the wire was coming down regardless and up front the only indication is power has failed and the SOP is to coast to a halt at a safe location.

Hardly worse than the red line as a whole though.

Transdev think is it:

The report from Luas operators, Transdev, says that an area on the green line past Sandyford is one of the most troublesome.

I meant the line as a whole that only refers to a stretch of the line as mentions it as one of the most troublesome sections not the most troublesome

Their top speed is 70kph. The tree was just passed the Ranelagh stop:

While the maximum permitted speed is 70 km/h, It is rare to experience much more than 65 km/h.

To be fair to Transdev and their drivers, speed control seems to be well disciplined.

I am not sure this is entirely true.

'this country' reads like you're suggesting it's particular to ireland.
i know of a case years ago (two colleagues were affected) where dublin airport was shut down for about two hours because a departing plane lost a windscreen wiper on takeoff (well, this is what my colleagues were told). plenty of our transport options are subject to such issues.
look at what happened gatwick with the phantom drone.
