Really? Says a lot about a vehicle that may have been on a PSV test or under repair...?
One X18 journey is allocated simply "Double Decker", this is until the winter X18 timetable returns. 7517 was on the pits today, plus the Sapphire on standby went out at 1530. There's no other choice than to allocate 7517.
