Construction features
The Karosa ŠM 11 is completely different from its predecessor, Škoda 706 RTO, which had engine in its front and two doors. ŠM 11 is model of Karosa Š series. It was derived from Karosa ŠL 11 intercity bus, and also unified with long-distance coach Karosa ŠD 11. Its body is semi-self-supporting with frame and engine with automatic gearbox in the middle, right between the wheels. Only its rear axle is propulsed. Front axle is independent, rear axle is solid. All axles are mounted on air suspension. On the right side are three folding doors (first are narrower than middle doors). Leatherette seats are used for the seats inside the ŠM 11. Driver's cab is not separated from the rest of the vehicle. In the rear part is room for a pram or wheelchair.
Production and operation
Production of the ŠM 11 started in 1965, continuing all the way until 1981.
Although ŠM 11 are not operated in public transport anymore, many of them are still being operated as historical vehicles. The last Karosa ŠM 11 in Prague was retired in 1987, and the last ŠM 11 in Czech Republic was retired in 1994 in Opava. About 9,900 Karosa ŠM 11 buses were made during its production.[1] Some buses were also exported to Albania, Bulgaria, Hungary, Mongolia, Poland and Romania as well.
