Today's post, 18th April 2011 features three pics from three different contributors, covering just two diesel classes.
The first pic shows one of Network Rail's locomotives that provide the power for the company's test trains. Class 31, 31465 in NR yellow livery, is pictured at Winwick, light engine, on 8th April 2011. The NR locos are allocated to the Railway Technical Centre, Derby. The pic is from John Smith.
Pic number two has been sent in by Richard Jones and is another of his excellent scans from 1992. In the shot, double heading class 37s, 37048 and 37255, are working empty low-sided wagons northbound, through Winwick, on 18th May 1992.
The final shot is of another class 37, and this one is from yours truly. DBS class 37, 37670, is pictured travelling southbound heading a short engineer's working, at Winwick, on 23rd September 2009.
