I was reading about the Pines Express, and an old article mentioned this crossing at Ashchurch, where the Midland main line was crossed by the GW Evesham-Tewkesbury line. It's a good photo but I still can't make out how the GW lines actually got across the Midland line. I don't think there are any gaps in the Midland tracks, though it's hard to be certain. And I can't make out any guide rails on the GW line that I thought would be needed if it would work a bit like a diamond crossing. There must be some moving parts somewhere. Any clues?
