Roadway always used numeric ID's for terminals - the further east the lower the number.. i.e. boston is 100 or so LA is 900 or so on and so forth
Yellow used letters like airposrt codes
indy = IND
Boston = BOS etc etc
\
\with the merger we will be using roadways system - and Cincy will remain 241 while to old Yellow terminal (which will be used as the main city operation) will gain the new number of 217.
this is going on all over the country - and a master list should be available soon.
