Interesting conspiracy theory - would be interested to learn where Stagecoach were secretly operating buses like this (other than MagicBus - though its not a secret that MagicBus are part of Stagecoach)...
The two companies are certainly competing pretty fiercely in Sheffield, and have been for a few years, so if they are secretly helping each other out, I'd like to know...
MAGICBUS was the original Glasgow brand that Stagecoach used when this service was established after Stagecoach Express in 1985 (with bus deregulation)
The name was sold to Kelvin Scottish for a period of 3 years in 1995, along with 9 buses (3 of which are still in operating with First Glasgow)
PM sent about the financial details
For operational reasons the "phantom operator" is usually quite easy to spot
Their vehicles will be white with no branding
However take the details of the operator plate and you will usually find Stagecoach is involved (either on the board of that company or directly)
Other phantom companies that Stagecoach have used are :
Perth Panther
ROGER
JOLLY ROGER
DEVON
FREE-BUS
The usual tactic now is to borrow vehicles from another subsidiary rather than from the "phantom fleet"
United Counties have several vehicles on their fleet, but they have certainly not been used on any services in that area!
The last major bus was in Inverness, using white vehicles
The tactic there was to replace all the existing routes, during the application process fares cannot be charged so all passengers were travelling for free, resulting in Highland (which had just been purchased by Rapsons of Inverness) withdrawing and almost going into administration
Fife also flooded routes to remove Moffat & Williamson from lucrative stage carriage routes
