Over the weekend Network Rail's 57312 'Peter Henderson' made a rare appearance on a NR test train. To make it even better, it was on my local line, not on a work day, sunny... and I had woken up!
I believe this may well be the first class 57 to have worked a test train!
57312 approaches Hersham with the 1Q13 train from Eastleigh to Eastleigh
via Havant and Waterloo. GBRf's 73204 was on the rear and lead the return trip.
