Here's an idea of mine.
If possible, send a few New Flyer D60HF Galaxy buses to Casleton, Charleston, and Yukon. They would be on the S57, 59, 61, 62, 74, 78, 79, 84, and 93.
Here's how many of the models the depots would have. The numbers are in parenthesis.
Castleton- (30)
Charleston- (16)
Yukon- (20)
What do you think? Questions/improvements?
