How will trains going 50mph going to cause queuing up to bank or leytonstone ? I see that they can't run at 50mph due to the track. Mile end to stratford is a long section of tunnel and I know 40/45mph is pretty fast but an extra 5mph to 50 mph will reduce journey times. Are they going to restore 62mph with these new bogies?

Because Bank and Leytonstone are bottlenecks.

As for the 62mph this is do-able in Coded Manual already though if you do it you'll probably get a big fat thumbs down from Peter Tollington, a Dunce hat and be forced to clean his desk for a year.

By around 20 seconds?

On the other hand that 20seconds were considered valuable enough for it to be the specification in the first place.

How long does it take to accelerate to 80 kph? I know 50 kph comes in 15 seconds.

0-50mph (80kph) achieved in 35 - 40 secs, depending on station, gradient, power supply etc. Figures recorded on dry rail. Back to zero from 50mph in 31 secs!
