When construction began way back in 2009, it was europe's biggest infrastructure project. but it was beset by problems and has opened 3.5 years late and £4 billion over budget. many of the delays to the project were put down to the complexity of integrating three separate signalling systems. to the east and to the west of london, drivers operate the trains manually, where more traditional signalling is in operation. the central core, however, uses a system of signalling called moving block. historically, what you would have is fixed block, so you have a colour light signal that tells the trai...

And much closer together than if driven manually, allowing an increased service frequency. we are running 12 trains an hour, and the reason we can drive the train cars a lot faster is because the computer controlling it is maintaining the distance between the trains ahead, so there is always a safe gap between them all, which can't be maintained on the normal network because of where the signalling system is set up. now, it has been a bumpy ride to get to this point. when construction began way back in 2009, it was europe's biggest infrastructure project. but it was beset by problems and has o...

Many of the delays to the project were put down to the complexity of integrating three separate signalling systems. to the east and to the west of london, drivers operate the trains manually, where more traditional signalling is in operation. the central core however uses a system of signalling called moving block. historically what you would have is fixed block, so you have a colour light signal that tells the train that the next block is clear ahead, whereas with us, the train is making its physical own block as it goes along the track, meaning you can run as many trains as you want to. i we...
