Ah, ok I apologise I’d been seduced by difference between the departure times from Stafford and Wolverhampton but that of course doesn’t account for the time at platform at Wolverhampton. One of my regular journeys is actually 14 mins, as below, but then sits at Wolverhampton for 5 minutes for no good reason, even Birmingham New Street only gets a 7 minute wait!Eh? XC are timed 12.5 minutes between the two and that includes a minute engineering allowance. Where does the 60mph come from? Considering they stop at both stations and it’s not 125 all the way.
So that gets it to c. 73 mph between the stations, and I get there’s some acceleration and deceleration time but that’s still not great.
