I had an idea about this. I was trying to think of a way to put PEDs on NR
platforms, where trains with pretty much any door geometry can turn up.


I'm just visualising that on the three platforms at Eastleigh - there's
seventy two sets of doors needed for the 12.450s... but at least their doors
are evenly spaced down the train. Then the 10.444 needs four permutations,
cos the doors are'nt the same position on all the coaches...

Yep I'm sure it'll be a goer, just need to get the DfT thinking about it...
