A strange sighting on the 127

An Alexander-Dennis Enviro400 MMC, 3103 (YX17 NLD), on Old Ashby Road on the 127 bound for Leicester on the 17th of February 2021. This bus was formerly based at East Midlands Airport as a car park shuttle bus, and carries the East Midlands Airport park and ride shuttle livery as well as an extra door in the middle, which is a rare feature for regional buses, as regional operators usually seem to prefer buses with only one passenger door.

Also note that the Arriva logo on the side is different to the new logo on the front.
