Orange Stagecoach Volvo's

From my personal sightings and information on the Stagecoach East Midlands Yahoo group three Volvo's at Stagecoach's Scunthorpe depot, two Paladin bodied examples and 1 Volvo B10M/Alexander (20414) have been repainted in allover orange - the same orange as used on the Humber Fastcat Livery. One of the Paladin's was in use on the 350 Humber Fastcat yesterday, and 20414 has been in use on the route today. Also a Dennis Dart SLF/East Lancs Spryte has been in use on the 350 both yesterday and today.

So this raises two questions - why has only one out of the four Scunthorpe Depot MAN/Enviro 300's bought to operate the 350 been in use on the service so far this week? And why do Scunthorpe depot now have three step entrance Volvo's in orange livery?

As a side note worth pointing out that Hull's 2 MAN/Enviro 300's are operating as normal on the 350 this week, and that Hull will be seeing a lot more MAN/Enviro's soon as new examples takeover the 1/2 Boothferry Estate routes.
