One thing that I've been wondering for a while is the reason why shorter trains have different stopping marks, so in the good old days you had a C stock stopping mark first and then later a stopping mark for the Ds or the As further down the platform. This obviously means that the front of, say, a D stock would stop further up the platform than the front of a C stock, but the back of the train would be in more or less the same place. Is it just so that if you miss the stopping mark, it's not such a big deal and you can perhaps stop at the next stopping mark? Two bites of the apple?
That would make sense and if that is the reason, fair enough, it'd just be nice to have it confirmed, but it obviously comes with disadvantages. You used to generally need two lots of OPO equipment (up on the Network Rail lines it can be more), for some drivers their stopping mark can be in a different place on a different day, depending on which train you're driving, which I would think could catch you out and it must've made a nice little challenge for those installing CSDE.
Of course, these concerns may be offset by the benefits of reducing the risk of overshoots and all the resulting hassle, I was just interested to learn of the reason, especially as the same rules apply with shunt moves and sidings and depots. Could it not plausibly be argued that it'd be easier to have all trains stop in the same place?
