Still don’t know why they didn’t do a standard for Spirit of Steam or Peak Forest. A tank engine in particularly could handle the missing local or station pilot duties on both routes and could layer into a route set pretty much anywhere in the country. Now we are restricted to the LMS region if we want a route with some layers.
I think out of the BR Standards, I’d go with a Standard Class 4 Tank, seeing as we don’t have any tank engines in the game yet. I’d happily take a Standard Class 5 or 9F though
Agree a tank engine would be more functional and I’ve always had a soft spot for the big 82xxx 2-6-4T’s.
