Not that they would (particularly given that they still have to contend with other trains on the network) but one has to suspect that in theory at least they could tighten up the timetable a fair bit if all their trains were this quick off the mark...Just want to showcase a video I've found that shows the insane acceleration of the 701s.
Previously the fastest that one had been recorded to clear a platform was around 22 seconds, already very impressive for a third rail train.
However this video shows it doing it in around 20 seconds, making for an average acceleration of around 1.02 m/s². To put that into perspective, that puts it on par with the Class 345 that uses 25kV OHLE equipment.
