Seen it a few times, but haven't managed to note reg details.
Stagecoach in Lincoln had a few odd workings today.
Saw an IC1 branded E400 and LN6 branded 300 on the 27 today.
The 400 came in, unloaded and went to head back to its stand (changing drivers in the process) - a supervisor/allocator of some type, came running out of the portakabin at one end of the station, running across to the new driver of the decker.
At this stage, I had no idea what was going on - but saw the allocator run off again and jump into an empty LN6 E300, bombing around onto the stand for the 27, which had a queue of confused conc pass holders.
The E400, bombed around and was abandoned on the stand for the IC1 (it wasn't parked... there's a difference

He then sauntered over the the E300, which was fully loaded (encouraged by the allocator rather enthusiastically) and not checked in on the ticket machine.
As my Brylaine was leaving, a driver had been found for the E400 and it was loading up for a run to Grantham (still parked at an angle).
Kept me entertained!
