I have once or twice had my ticket checked on a Thameslink train but only on a small percentage of journeys. Unless tickets and railcards are checked on every journey and passengers know their ticket is certain to be checked there could be a potential risk to revenue especially on journeys covering much longer distances and therefore with much higher fares and than Thameslink and other current driver only operated services.
That potential risk to revenue is actually rather small. Especially with £100 penalty fares.
At what point can they do that?
NR can do it now (Implement the proposed change in maintenance)
State Pension and benefits are getting 10% and they're not even paying the taxes that contribute to those Government bills.
Plenty of people pay tax on their state pensions and benefits.
