A very grubby 144009 slows down for the stop at Crowle whilst working the 09:03 Doncaster to Scunthorpe service on 1 May 1999. The line runs parallel with the Stainforth & Keadby Canal for some distance here. Presumably the odd cantilevered signal gantry is to improve sighting, although I would have thought cutting the bushes back would have been easier!
