Whilst leaving platform 1 heading westbound at White City, I've noticed the trains seem to start out much slower and seem to be coasting through the points when I was traveling on the 30/06 and 03/07. Is there a TSR around that area at the moment? What's the reason for the TSR if there is one?

Central Line ATO can't coast (I've been off work for the last eight days and didn't notice any slow start before that)

Maybe coasting isn't the right way of describing it.
It felt a little like leaving North Acton going westbound towards West Ruislip, where the train speeds up and slows down when it gets close to the points leading to West Ruislip and Ealing Broadway, then as soon as the last car passes the points, it speeds up quite quickly after.

Currently a TSR white city w/b departure - I can't 100% remember the reason but off the top of my head I would say cracked rail. |

Central Line ATO can't coast (I've been off work for the last eight days and didn't notice any slow start before that) Technically they can, but coasting vectors are turned off and have never been enabled as far as I know. There is talk every so often about turning the coasting vectors on but it's never happened. |

There is talk every so often about turning the coasting vectors on but it's never happened. So how would that work? Would the system determine that the train needed to be at a lower speed at some particular point in the future, but that braking could be delayed, as it could be done later with an acceptable deceleration rate. This would save energy (even if re-gen were available), and wear and tear on any mechanical brakes if they would have be needed. Or is it much more complicated than that? |

Very simply the ATO data has set points along the line where coasting begins and ends if the coasting vector is set.
