No, the 95TS are restricted because the Northern line hasn't yet had its
signalling system upgraded. When that happens and ATO is implemented,
then they'll be let off the leash.

There must be more to it than that. There's no reason they couldn't have full
acceleration but with the top speed still limited. The signalling as an
excuse makes no sense to me , there is a fixed distance between signals and
its up to the drivers how they get between them. Surely getting up to line
speed as fast as possible would benefit everyone?

Not if that means you are travelling too fast (to stop) when the next
signal looms into view. And then there's the energy consumption.
