As is well rehearsed by rail ministers DafT does not get involved in the detail of running franchises.
Here's a non-example from the South Central Franchise Invitation to Tender.
"Bidders’ attention is drawn to the problem of delays between train arrival and door opening at Victoria associated with problems with the GPS signal at that station. This often means that whilst a train is at a stand passengers have to wait 20-30 seconds before the doors are opened.
"Proposals are sought as to how this issue can be remedied with a view to a solution early within the life of the franchise."
Not a sparrow falls
