Big diesel void leads two former Network Rail Class 31s to Mangapps


By Geoff Courtney

AS HE bid farewell to No. 31430 Sister Dora in October, Mangapps Railway Museum boss John Jolly feared he would suffer from withdrawal symptoms, for the Class 31 was the sole remaining ‘big’ diesel on site.

And with that overhaul completed, the A1A-A1A moved to the Spa Valley Railway on October 14, as reported in last month’s issue, leaving John’s diesel stable comprising only shunting locomotives, including four ex-BR Class 03s and a Class 04.
