In the 1970s Trans Pennine units were commonly seen with a DMC missing and what we had at BG placed on the front, occasionally both DMCs wee missing. The replacement could be anything from a Met Camm, Cravens or BRCW. Usually a DMC of the Met Camm/BRCW fleet, but every know and then a Twin would appear.
We also had a period around 1977 when availability was poor a set was turned out using only Trans Penninr TSLs, it had for at least one trip a MBSL in the rake untill some one mentioned the lack of hand brake, this was soon removed and a BG substituted. This set had an out and back job to Goole in th morning and evening usually with a Brush 2.
Trans Pennines could also seen been with a tail load on the 04xx Donny Hull when it ceased to be a loco hauled job, 2 BGs been normal for a 5 car Pennine.
