(24 Feb 2015, 7:21 am)Dan wrote Some runs are operated by gas buses, interworking with service 13.

Others interwork with service 4, so if a gas bus appears on one of the runs attached to the 4 service, it would have been an odd working.

Only two have any inter-working with service 4, one is a guaranteed ADL Enviro 200 and the other is one that usually end's up being the gas bus on the 4.

All X1 inter-working is as follows.
