Gawd! I’d be stuck. I think until modern times most everything here, came from elsewhere.
I need to go to (my local) the Australian National Railway Museum to research this issue. BTW As a non-card carrying member in the Triple R (#52 in case I do get issued a badge) though, it does have a nice Roundy Round.
Wait a minute, I don’t think we did snow plows here. I’m not going to have a snow plow, Devon. (at least not until I read about making realistic snow from bean bag chairs, cat fur etc. on the LSC.)
