A scene that epitomises railways in the Fens in the 1980s. 47292 approaches Chainbridge with the 9H35 11:10 Wisbech to Whitemoor Speedlink trip working on 16 August 1988. The Wisbech branch is all that remains of the former through route from March King's Lynn. I think this is the only occasion that I have used a polarising filter in combination with the Pentax 6x7 on a railway subject, but here it accentuates the typical big sky of the fenland landscape. The loss of 1½ stops when using such a filter with ISO 100 film on medium format is no joke, but luckily here the train is slowing on the approach to a level crossing, so a shutter speed of only 1/250 sec could be used.
