Thanks for posting your experiences of doing almost the exact conversion and modelling that I am currently undertaking.
Your mdels look good!
I hope the ones I am doing look as good once completed.
I have gone about the bogey/wheel convrsion differently thoough, getting US type bogies in the UK is not easy.
i am using an etched subframe within the existing bogie mouldings.
More on thaat once I ge it done!
The railguns plus support wagons will be in Winter Camo paint scheme as that is what the guy has asked for.
The support vehicles are a bit more of a diverse colour ranging from the Yellow to the Winter mix - all good fun!
