60001 & 31271 Castor 11 April 2015

An unusual pairing at Castor on 11 April 2015, during the Nene Valley Railway's Diesel Gala. Visiting DBS 60001 & 31271 Stratford 1840 - 2001 work the 2E51 14:02 Wansford to Peterborough service. The signal does not indicate a conflicting movement, and did not move all day!
