Signal Failure – The Achilles Heel of a Driverless Light Metro

Portend of what is going to be more and more common on SkyTrain, signal failure.

As our SkyTrain ages, more and more service is disrupted by signal or a switch failure and with almost no redundancy in our transit system, the results for the transit customer is a fiasco!

The lesson is simple, the more complicated the transit system is, the more chance of catastrophic failure!

A lesson that the SkyTrain Lobby ignores.

DLR down: Transport chaos for commuters after entire tube line suspended due to signal failure at West India Quay

The line has been down since 9.15am

The entire length of the Docklands Light Railway (DLR) line in London is currently suspended due to a signal failure at West India Quay.

The whole line has been down since 9.15am on Tuesday 18 September, with problems first reported at 6.15am this morning.

 London Underground, London Buses and Southeastern will be accepting valid DLR tickets via any reasonable route, according to Transport for London (TfL).


The failure has coincided with an event being held by the DLR this morning called “Meet the Manager”, a Q&A at Canning Town from 7.30-9.30am. Billed as an opportunity to have any DLR questions answered, it is unlikely that many people will be able to get there while the line suspension continues.

 Thousands of commuters have also had their journeys disrupted by the suspension.

Rachel May Quin tweeted: “Shout out to London DLR for a catastrophic service this morning and implementing a full suspension on all routes. You always know how to brighten my day.”

Meanwhile, Lisa Terry wrote on social media: “Great start to the day. Severe delays on London DLR so follow advice and go to London Bridge to get tube to Canary Wharf. London Bridge underground closed. OK, I’ll get the train to Waterloo East. Nope, London Bridge train station had closed behind me.”

The DLR twitter account has been replying to complaints, advising that customers can claim a refund for delayed journeys online.

“Our engineers are on site and are working hard to fix this,” said one customer service advisor. “I honestly can’t say at present when this will be resolved. Sorry for the disruption.”

The DLR is used by commuters to get to stations including Canary Wharf, Custom House for ExCel and London City Airport, a key hub for business travel.

    I know it’s wrong to laugh at someone else’s misfortune but wow, on the day of a “Meet The Manager” Q & A session your whole multi line rail system goes down. I would not want to be that manager! I would like to be a fly on the wall for that first phone call that particular manager got. Imagine the scene, a guy or gal alone in some room outside of some local hotel ballroom or large public meeting room screaming into his or her phone, “you had to shut down the whole f**king system? Do you have any idea where I am right now? Many of the local Tube stations are shut down too! I think I am going to need a police escort to get out of here! Who do you call for that?”
