Difficult to recognise now, but I'm surprised the path is still there. The houses behind you left are built on a filled in brick pit. Opposite there used to be the war time Ministry of Supply depot, connected to the down relief near the crossing. Up main just where you are standing is part of the scene of derailment of the Birkenhead Paddington goods that also demolished the front of the signal box, circa '65.
Cheers for the memories as usual, all of that sounds familiar from photos I've seen of the area back in the day! It's lovely to know authentic locomotives still travel along here. Regards, Dan
