1. The cost savings of a smaller fleet is minimal compared to the headaches it would bring. Save the S57 these routes are weekday only meaning the mileage would be not proportional to the other buses and if there was a shortage of any 40ft buses, you bet that these smaller buses would be showing up on the other routes. Also a lot of these routes interline so that would be another difficulty with this. For routes that are part time, it’s just not worth it.
2. I believe non of the depots can support attics atm.
