Let's assume it's highly unlikely the driver of a number 490 bus from Norton Bridge would instantly issue you with a CDR to Northampton, a SVR to Norwich or whatever through ticket is required.
Would you, IN THEORY, get on the bus and, as per the NRCoC, buy whatever ticket you could for the first part of your journey, then exchange that (bus) ticket as part-payment when you get to the (open!) railway station? Would staff at Stafford or Stoke stations expect or know how to do that?
Because if things like that are not possible, could it not all add fuel to the potential claim that the long-term supposed 'bus replacement' for Norton Bridge, Barlaston etc is not fulfilling its purpose and that the stations have therefore completely and finally closed by stealth without statutory procedures being adhered to.
