“The trains which traverse the lines of rail beside which the body was found are those which run from west to east, some being purely Metropolitan, and some from Willesden and outlying junctions. It can be stated for certain that this young man, when he met his death, was travelling in this direction at some late hour of the night, but at what point he entered the train it is impossible to state.”
“His ticket, of course, would show that.”
“There was no ticket in his pockets.”
“No ticket! Dear me, Watson, this is really very singular. According to my experience it is not possible to reach the platform of a Metropolitan train without exhibiting one’s ticket. Presumably, then, the young man had one. Was it taken from him in order to conceal the station from which he came? It is possible. Or did he drop it in the carriage? That is also possible. But the point is of curious interest. I understand that there was no sign of robbery?” [BRUC]
The Metropolitan Railway opened its first line to the public on January 10, 1863 (just after Holmes’s own 9th birthday, per Baring-Gould). Of course, by the time we join Holmes and Watson in London, the Underground is already well-established.
My friend rose lazily from his armchair and stood with his hands in the pockets of his dressing-gown, looking over my shoulder. It was a bright, crisp February morning, and the snow of the day before still lay deep upon the ground, shimmering brightly in the wintry sun. Down the centre of Baker Street it had been ploughed into a brown crumbly band by the traffic, but at either side and on the heaped-up edges of the foot-paths it still lay as white as when it fell. The grey pavement had been cleaned and scraped, but was still dangerously slippery, so that there were fewer passengers than usual. Indeed, from the direction of the Metropolitan Station no one was coming save the single gentleman whose eccentric conduct had drawn my attention. [BERY]
