Gresley K3/3 class mogul no. 61889 crosses the Sluice Bridge just north of Boston in 1953. The train is probably a Cleethorpes to King's Cross service. A viewer has noted that the former GNR Hill Halls sleeper works was located behind the carriages.
Note the odd positioning of the shed plate which seems to be set much higher than the norm.
