Explanation
The statement is false. Stagecoach did not own South West Trains before losing the rights to FirstGroup and MTR in March 2017. Prior to March 2017, South West Trains was operated by Stagecoach in partnership with Network Rail. However, in August 2017, FirstGroup and MTR took over the franchise from Stagecoach.
