Toton was the spiritual home for the LMS Beyer-Garratts which were intended to eliminate double heading on the procession of coal trains working south down the Midland main line. No.47979 had been allocated to the shed from new in September 1930, although it was to be transferred to Hasland in August 1956. Here it is adding to the cloud of the smog over Toton on 17th March 1956.
