Good Lad for sticking to your guns.
Just because someone maybe has never seen something done dosn't mean it's never done. A loco may have failed and a V is the only engine in steam available then a shed foreman would 'pinch' it.
Once on Stockton station pilot with an L1 either 7754/9/64 or 66 we only had four of them a K1 went through towards York with a class b--(H or
depends on your era. half an hour later the station master came , would we go to Eaglescliffe and bank the K1 up Picton bank-I bet some people have never seen that done either.
Incidently a friend has one of the 00 gauge Bachmann pacifics A1 or A2 and the local know all in his club told him to take the front coupling off the engine as they never used them in real life!!! I can remember in the 50s while working a freight from Low Fell to Teesside looking up at a main line train going towards Newcastle pulling the Pullman tank first. The train engine had failed at Durham-good job his front coupling hadn't been taked off.
Now my GWR-(spit)- Great Bear I use in the Berry Wiggins sidings to steam heat the tar wagons..........
I wish Bachmann did an 0 gauge model of a V tanky or even an L1.
happy modelling......Jim Brodie.
