"Idiots... all of them"

Clapham Junction is an extremely difficult station to use, and I imagine operating it is no picnic, either. But millions have been spent trying to improve the user experience, largely in vain as a result of the ineptitude of a few morons. Here's an information display on Platorm 2 last night:


So... on a "one train in steam" shuttle service, the 1748 is going to arrive before the 1725?

The sign was obviously wrong, although that wouldn't help anyone but a train geek (and in the end the 1725 turned up at, er, 1725).

More bizarrely, why isn't a self-contained branch (Clapham Jct-Shepherd's Bush, the rest of the line closed for engineering) being operated as an even-interval clock-face service? Why do you have to wait 23 minutes in one part of the hour, and 37 minutes in the other?
