To ask the Scottish Government, further to the ministerial statement on ScotRail on 9 February 2022, during which the minister stated that "success for Scotland's rail services...includes ensuring that they...generate increased revenue", by what date the "increased revenue" is required to be delivered; what base level of revenue is being used; what level of "increased revenue" will it consider a success, and what action it plans to take in the event that the required level of "increased revenue" is not achieved by its target date.
