Before the Ordsall Chord opened you could legitimately overtravel to Salford Crescent on a Stalybridge-Manchester Ctlz ticket as the mileage Stalybridge - Salford Crescent and doubling back to Piccadilly was fractionally shorter than Stalybridge-Manchester Piccadilly direct. Break of Journey was permitted on the outbound. The staff at Crescent really didn't like it though.
The price of a Stalybridge - Manchester Ctlz return was the same price as a return to the Crescent!
Stalybridge-Glossop is a bit of a pointless fare, at £6.50 return, it takes an hour and a half and you have to travel via Manchester Piccadilly because TPE don't serve Guide Bridge.
The 237 bus is half an hour faster and £1.50 cheaper with a Stagecoach Dayrider.
