London Assembly Tories propose driverless Tube trains

There'd be no one to shut the doors at Kennington just as you're rushing to change trains from the Bank to Charing Cross platform. But the computers could be programmed to shut the doors perfectly to miss connections. ;-) Being serious for a millisecond the bit that the paper does not mention is the cost of having to provide full height or half height platform edge doors if the trains were to be fully driverless - i.e. like the Singapore North East line or VAL systems. I think the half height solution is being deployed in Paris and also in Japan and in Singapore on the older lines whereas Singapore has PEDs on the newest lines like the Circle and North East lines. MTR in Hong Kong has retrofitted a lot of places with PEDs but not sure if that covers the few open air / viaduct stations there. Given the long standing propensity for Londoners to "chance their arm" (literally) in leaping through closing tube doors there would be a huge culture change needed if trains were to go fully driverless rather than DLR style. Given the systems are much newer in other countries there is no long standing "misbehaviour" to deal with. There are also interesting issues like curved platforms in London which make CCTV monitoring harder as well as how you deal with the physical installation of PEDs or similar. I'm not in the habit of giving credence to Mr Crow but I think an interesting debate could follow on as to Londoners' attitudes to driverless tube trains etc. A lot of research shows that passengers like a visible staff presence on trains and in stations - hence the staffing strategy on London Overground. Past experience has suggested that some "safety based" strikes or disputes garnered some public support. It looks a bit like Mr Crow is trying to do the same here. I note that the previously seamless connections at Poplar on DLR are now not quite so seamless with trains departing just as others arrive or the "RTD" message beeping on one train before it does on the opposite one thus shortening interchange times. I guess the much more intensive service levels means every second counts in keeping to schedule. -- Paul C via Google |
