Readers who suffer less than I do from "Too Many Birthdays Syndrome", to wit, young'uns; might have noticed here and there nowadays, and more so in old photographs, sidings which end up against a bank or what looks like an end-on platform. Some of these have ramps up to them from the "land" side.
These are where road vehicles could be loaded onto railway vehicles - flat wagons or, for elegant horse drawn carriages not to be exposed to nasty old coal smoke from locomotives, covered vans. These were known as "carriage trucks" or "carriage vans" - nothing to do with railway carriages, more so road carriages.
After infernal combustion cars were invented, if a road vehicle was to go by rail it would tend to be loaded (in the same way) onto a flat wagon.
I attach - possibly even the right way up - drawings of a GSWR design, though all railway companies had them. How else were the gentry to carry their varnished horse drawn carriages from Dublin to wild, exotic remote places like Cappoquin, Raphoe, Ballindine or Magherafelt?
The loco would shunt one of these vans into the carriage dock, while the footman or carriage driver of Lord Whatis-Name (has to be double-barrelled) loaded the carriage, which was then attached to the back of the passenger train in which the good Lord and his Ladie(s) were travelling. A horse box, of course, might be also attached (of which the GSWR alone had over 100 of at least four different types).
Naturally, the mere peasantry, the Great Unwashed, hoi-polloi, commoners, IRM readers and Ordinary People were welcome to watch. From a suitable distance, of course; we mustn't upset Lord Whatsis-Name, lest he increase our rent again.
Well, the original picture was the right way up.....
