350129, LM 11.33 Birmingham New Street-London Euston (1W12) & 57313, 47746, 10.32 Southall WCR-Carnforth Steamtown (0M43), Northampton station
I had been observing the progress of a strange working
heading northwards along the WCML for some time on Opentraintimes and figured that it would pass through Northampton station just as our train south would arrive. I was spot on with my estimate as here it is being led by 57513 and 47746 passing the 11.33 Birmingham New Street to Euston formed by 350129. The 57 and 47 combo with 57001 and 33029 along for the ride on the rear, were forming the 10.32 Southall WCR to Carnforth Steamtown
