RE: Arriva North West - St Helens Depot
As far as the heating is concerned, they're run by a thermostat. Once the ambient temperature drops below a certain level the heater motor kicks in. Then when an ambient temperature is reached it automatically switches off until the saloon cools down. Invariably this is when the bus opens its doors at stops.
Judging by the Southport ones this system is quite effective.
