The vehicles may only be being half filled - so a swap occurs later.
Half of the bay may not be working, so half of the fleet can't be used.
There could be a whole range of reasons, but an educated guess would say there was some sort of connection with some of gas buses not being out and apparent problems with the fuelling station.
I think you're right. As I have just noted on the rare and odd workings thread, there is an ALX300 out on service 20 today which is allocated the gas buses during the week.
