2-6-0 Ivatt Class4 "Mogul"
I thought this would just be a few changes to the 2-6-0 Standard 4MT www.flickr.com/photos/bricktrix/sets/72157628496638061/ but how wrong was I?!?
Being the predecessor of the 4MT, I really wanted to get this built to double-head with each other.
Its basically been a complete rebuild from chassis upwards and still ongoing....I think the only thing the same is the front pony truck!
Major changes include higher and thinner running boards, new valve gear mechanism, different cab and underboard pipework.
Testing so far has seen no problems with the running gear, so all is good :)
