that double-decker tramcar would probably weigh in at about 10 tons empty and probably less than 15 tons with every seat full and crammed to capacity with standing adults- Remember then you used to get more adults/ton than you do these days
All braking would have been done by the tram motor (dummy), with probably only a lever parking brake on the double-decker trailer car.
So who needs full-sized knuckle couplers for such a "tiny" load - A flat drawbar and some decent pins and some safety chains as backup will do the job

John, you just have to learn that some times--mainly when I'm awake---- I am snarky and sarcastic. Bourbon, properly administrated, helped to alleviate the condition in the past, but now the Doc doesn't want me to drink. Grrrr.
