Platform 1N at Dundee is 96m between signals D755 and D746. Neither signal has standing ahead controls. The total length of 4x mk5 coaches and a class 73 loco is 105.76m. Back to the drawing board.

"Standing Ahead Controls" I presume is the ability for a train to shunt onto/leave a platform with the leading end past the platform signal?
I'm fairly sure I've seen this at Swanage when we went there a few years back (with the rebuilt Merchant Navy beyond the starter?), but can anyone explain how this works (both modern day and previous times I guess) and how common it is these days?
