>From a discussion forum about the San Francisco Municipal Railway (which despite its name includes trolley buses and diesel buses as well as streetcars and cable cars).
The writer is a retired Muni motorman (Bob Murphy) who has retired to Australia, replying to a message from an former Muni inspector named Art. The topic is the weight of various types of old (1948-1975) trolley buses; I remember all of them, having grown up in San Francisco. Carleton P.S. MH means Marmon-Herrington, SLCC means St. Louis Car Co., and Twin means Fageol/Twin Coach, the three trolley bus manufacturers from which Muni bought its equipment. ETI is the current fleet (third generation), in between were Flyer trolley coaches from Winnipeg. Trolley bus (or coach) means a rubber-tired vehicle powered by electricity from overhead wires.

According the the "Schedule of Rolling Stock" dated June of 1958, MUNI's Trolley Coaches weighed as follows, in pounds: MH 526 & 528-549 = 17,920 MH 550-569 = 18,500 TWIN 570-659 = 18,560 MH 660-739 = 18,500 MH 740-789 = 18,960 MH 790-849 = 18,750 SLCC 850-889 = 20,529 I don't have the Flyer TC weights handy. Obviously, the St. Louis coaches were the heaviest of the original TC fleet. I suspect that the current standard ETI's may be heavier because of the huge battery packs they carry around. It's very interesting that the "Operator's Manual" for the ETI's gives height, length, width, overhang, ground clearance, turning radius, etc. - but does NOT give the weight of the coach!! Does anyone have the ETI weight?? Art
