Buy a Gtr Manchester Rail Ranger and it's valid for the cross-centre trams. As are the majority (AFAIK??) of rail tickets with Manchester (any station) as the destination and, of course, cross-Manchester rail journeys. Bought a System One Rail/Bus daysaver, and expected to be able to use it on the tram between Victoria and Piccadilly. But I e-mailed TFGM and apparently that's not the case, which seems a bit odd. Anyone used the B/T daysaver on city centre trams and been pulled up over it?
