Hi, I am looking at doing a couple of mods for Nimby Rails but I've got no idea where to start. I've looked at the modding guide and I'm still lost, could you help?

Indeed. Definitely going to see if I can incorporate them into any heritage lines though, so I'll hopefully get some use out of them :D

@Ant Craft
I am glad that you like them. As for my "older" mods, I think the 87 served the Caledonian Sleeper until last year, and that's a formation which is included in the mod. But yeah, no place for the other stuff on a modern network.

Oooooh thank you! Been waiting for a proper 345 for a while now. I know there was other 345 mods, but since they used one of the default trains, it wasn't realistic enough for me. So thank you! Also wanted to take the time to thank you for the 710, 701 and 80X trains too, as well as the others, but since I am doing the modern day network, I probably won't use them, but maybe I can think of a use for them on a heritage line or something.
