You do realise the drivers cannot see what's happening on the other
platform at Kennington?

There are usually staff on both platforms that could tell them to hold
the train. There is absolutely no doubt in my mind that they do this
totally on purpose.

Railway staff obey rules or they get sacked. With headways every three
minutes, it seems unnecessary anyway, so the orders that come from above
seem to be good ones to me. At Harrow-O-T-H, where the headways are much
greater, trains are held IIRC.
