From Chums, 4 January 1893
OK maybe there is a bit more to it. So, here is A Run with the Mail Van:
The Western Mail is one of the most remarkable trains in this country. It leaves Paddington station each evening at nine o’clock, and goes its way to the Land’s End like a great feeding machine, supplying in its transit nearly every western town with letters. It was with this train that I was to journey, and at half-past eight o’clock I found myself in Paddington Station, chatting with Mr. King, the superintendent of the two mail vans, the general custos rotulorum, and the especial guardian of all the important documents and parcels which go from London by this mail. The whole scene was then very busy. The terminus glowed with dozens of fine huge electric lights, porters were bawling, passengers were hurrying, luggage was being hurled here and there, a great express locomotive was being backed against the night express, and all was confusion, bustle, and method.
