Answer

Farebox revenues refer to money that is collected at the time of boarding. A farebox is a cash box that holds the money that passengers pay when they come on board. If they receive tickets at the time of boarding then farebox revenues would come from those ticket sales; however, money for ticket sales could also be collected at the station or some other location before passenger boarding and would not be included in farebox revenues.  

Without more context it is not possible to determine the meaning of BTC. It could stand for British Transportation Commission or Baltimore Transport Control, etc.

Answer

The BTC is the British Transport Comission.  I'd understand "farebox revenue" as meaning money from selling transport tickets.

I am not sure about what BTC stands for. Most probably it is abbreviation of B......(name of a place starting with B) Transit Center.
