What about the guy in charge of a packed 12 car DOO commuter service in to any of the London terminals? He just goes by driverThis was further upgraded to Train Manager for what had been Senior Conductors; again, I suspect, a status thing. To be fair, the guy who takes charge of all passenger-related stuff on an 11-coach Pendolino from Euston to Glasgow probably merits a better title than Conductor (even with the Senior prefix).
They should call us Executive Train Service Delivery Agents or some other rubbish haha
