In the early 80’s the GEML was being electrified and I used to visit my local station to see the Electrification train stabled in the old goods yard. On one occassion there was a Tool & Mess train stabled there. I thought that it would be nice to model something similar. I took a few photographs and then checked my model stock to see what I could make. At this point I realised that an exact copy of the train was not going to happen, but I could get close. A good supply of Engineers Olive was acquired, then the stock modified.
Considering this was nearly 30 years ago, the models still get good commemts at exhibitions.
