I'm old enough to remember seeing passenger diesels wreathed in steam from leaky joints (at intervals along the train as well) on cold days in winter. What never occurred to me at the time was the likelihood that the rear carriages got less heat as the steam supply cooled along the train - and I don't remember ever seeing a trail of steam emerging from the tail end of a train, which surely it must have done to keep fresh, hot steam moving through the system?
Any photos of the end of a steam heated train to back up this theory?
Thanks!
