Just been speaking to an acquaintance who, as a non-driver having business in London and Oxford, uses trains from Penzance on a fairly regular basis. He told me of his horrible journey on Friday night from Paddington on the 19.00, train rammed and no air con working over the whole journey: the TM was making valiant efforts with water being brought on at various stations to alleviate matters, so no tickets were inspected at any stage (almost unprecedented these days) and the train was very late arriving at PZ. In this Brave New World Scenario, what is to prevent that whole journey being made with driver only 'in extremis' - I realise it is more than one duty, but during disruption it could easily happen that consecutive duty bods were missing. Suppose somebody collapsed and died of heat exhaustion during one of these all-too-common failures of aircon: one could imagine a coroner recommending that no long distance train be allowed to proceed without a member of staff other than the driver present.
why would it need to be 'in extremis'?
FGW wont clear up exactly what they mean by 'disruption' or what they mean by a TM (not necessarily a Train Manager) will be 'booked' to each journey!
