Is there a reason some Thomas locos don't have road numbers. In particular Bill, Ben, Emily and Diesel? Also most are 2 digit road numbers whereas Salty's is a 4 digit number.
I only noticed because I am converting them to DCC and using the road number as the address would make it easy for my grandson to call up a loco, just look at the loco and punch in it's number.
I guess I will get busy with decals.
Diesel is a demonstrator of the class 08 switcher, Bill and Ben belong to a different company in the books ( they have numbers in the books) but they belong to STH, Emily has no number because the origanal model makers never put on a number, I guess you could use the first letter in their name like D for diesel but Bill and Ben might need some thinking ( Bl for Bill and Bn for Ben?)
you can add your own numbers with decals. most dcc systems I know of don't allow the use of letters as addresses.
