The Tube: Making sense of signal failures

Tuberails

Everyone, and by everyone I mean all Londoners, complain about train delays on the tube. It’s a natural part of the goliath system that is the London Underground. I think most Londoners didn’t get the memo regarding how their subway system is one of the best in the world, but we’ll humble them anyways. What causes delays? Signal failures. What are they? Well, the Londonist did the homework for us.

On our way to the Londonist Dungeon this morning, we were unlucky enough to be travelling in the Central Line as it went absolutely tits up. Our friendly and throughly engaged driver told us that the problem was a signal failure at Bethnal Green. Having used the Central Line for nigh on 12 years, we’ve become used to this kind of bestial shit, but this morning we found ourselves wondering…”What does ‘signal failure’ actually mean? And why do they happen to the Tube so much?”.

It felt time for a little bit of investigation.
