Really?
Transport Scotland have financed the Operation for the past 18 months have they not?
Serco are well funded by the taxpayer in various government contracts, ranging from failing Track and Trace to tagging prisoners that didn't exist!
For the last 18 months, Serco will have been on a form of contract that enabled them to make a very small % profit on costs. In that time they might have earned a few hundred thousand pounds profit (complete guess based on 2% of costs). That is set against tens of millions of losses for the previous years.
