i don't know when but i herd that h'ville was the only branchline that could take an R class. is this a case of bull manure or is there something behind that statement??
If it can hold a B class which it's total mass is approx 114t and history has shown the track will hold this locomotive no sweat (i'm not including the load it was carrying at the time)
R class.. ummm I don't know as the R's total mass including tender in working order, comes to approx 186t, so I don't know.. you'll be pushing it..
Speaking of which a "S" class (diesel one) a "mainline" locomotive comes in at 116t so i'm pretty sure an S class would be another welcomed visitor..
Lets not forget the diesel "X" class which weight is the same as a B class.. hint hint..
