Approach-control signal, Moorgate Met
 

Does anyone know the purpose of the apparently approach-controlled
signal in the middle of the platform on the westbound Moorgate
Met/Circle/H&C platform?

I don't recall ever *not* having been slowed half way up the
platform.

I have, on a few occasions. Maybe it depends on the drivers skill?

But surely a driver who is late and/or in a bad mood would just speed
up again before slowing for the end of the platform so what purpose
does it serve other than to delay the train? Also given its the 21st
century couldn't it only work if theres a train in the bay platform?
Theres hardly likely to be a collision if theres isn't not matter
what.

I think they were thinking of it blocking a train on its way into the
bay platform, although I don't see how it could be that close, because
there's a trailing crossover between the platform and the one that
leads to and from the bay.

And although I don't know anything about driving trains, I would have
thought that it would be easier to judge the stopping point if allowed
to drive normally into the station than if forced to accelerate while
partly in the platform.
