A while back I found an old Mainline 12T BP tank wagon in one of my boxes of bits which I thought could do with a bit of an upgrade. The model dates back to the late 70’s which at the time was a pretty good model but by todays standards its pretty naff.. First to go was the chunky chassis to be replaced with a Cambrian models 10’0″ underframe kit (C105). This needed some headstocks adding and I fitted some Lanarkshire models cast buffers to these.
The tank itself isn’t too bad but I cut off the moulded ladder and walkways and replaced them using a Rtmodels etched detailing kit for the Airfix B tank. The ladder needed shortening a little and the rest is easy enough to fit. Other details were added with bits of wire and microstrip. It was given a coat of black paint and some Cambridge custom transfers added. It might not be 100% accurate but its a lot better than it was.
