One of the X5 Elites passed me on the A10 lunchtime being dragged down to Volvo at Ely.

The drivers at Bedford will probably have a party when those are replaced. They've been nothing but trouble since they were new.
They're by far the most unreliable coaches ever to work the route

Arriva - Guildford Leas Rd depot has had @ 14000 litres of diesel fuel stolen overnight.
It seems that thieves pumped the diesel across the river Wey via a long hose to a vehicle on the opposite bank (The river is only @ 40 ft wide at this point).
The theft has caused a diesel spillage into the river.

Solo SR 48036 (YJ66ASZ) is the latest vehicle to be repainted into Local livery at Bedford and is now parked next to the recently arrived ex London E200's. It however remains out of use and hasn't been in service for over a year.
It would appear that the paint shop are not now focusing on one vehicle type at a time

Just looking at bustime.org and the Cowley road allocation and saw this!

Did the vehicle do that trip or did someone borrow the ticket machine?

Could it be a ticket machine swapped between vehicles?

It's a deinite. The ticket machine is what reports the tracking ID if I remember correctly.
