The train ran this morning but it was so cold (as it was one of those buses on rails) I could see my breath. Does anyone know if there are any rules for minimum temperatures allowable on public transport?

Sadly I don' think there are any regs, but it would of soon warmed up after all the commuters had cammed in at Bath

There are no regs on minimum requirements, but the reason for the dodgy heating was probably the fact that since FGW pulled out of the Canton depot at Cardiff, to their new (unfinished) depot at St Phillips Marsh, there is a severe lack of parts if anything goes wrong(for Sprinters), and also a lack of fitters to complete any repairs. An example of this is the 158 which has been on the depot at Exeter St Davids for at least two months waiting for a new side window for the drivers cab. While it has been sat there it has been stripped of many parts to use for repairs on other 158's!
