Never mind is it going to be a Class 59, 60 or 66 on the Theale Murco tanks, in the late 1980s this was the regular traction, virtually guaranteed! The last of the weak summer evening sun catches 37294 & 37280 (a regular pair at the time) as they growl past South Marston with the late running 6B27 16:48 Theale to Robeston empties on 4 August 1989.
