Here's a silly idea. For any given NR terminus platform (e.g. KGX platform 7), what's the shortest distance you can drive a train without stopping or reversing so that the train arrives back where it started but the other way round.
E.g. KGX 7, up to Newcastle, round the loop there, back down the ECML again. You could also do Leeds 6, Staleybridge then round Guide Bridge/Ashton back to Leeds again.
Ignore gauge and type. Turntables not allowed. Bonus points for the terminus/platform with the very shortest distance.
