The Karosa B 931 is a Czech city bus that was produced between 1995 and 2002. The vehicle is 11.35 m long, 2.5 m wide and 3.17 m high. The drive is usually provided by a single Renault engine with a power of up to 255 HP, although other power units are also used (e.g. the LIAZ ML 636 engine with 238 HP). An automatic gearbox with gears from 3 to 5, depending on the version, is responsible for the transmission. The Karosa B 931 bus was created as a successor to the B 731 bus of the same manufacturer. Compared to its predecessor, it has kept the previous dimensions, but its front and rear have been rounded, it also uses other power units and - most often - a different drive train. The Karosa B 931 bus also received such systems as ABS and ASR. In 1999, a modernized version was introduced, designated B 931E, which is characterized by, among others, a lowered floor in the front of the vehicle and the blocking of other brakes. Karosa B 931 and B 931E buses are used primarily in the Czech Republic and Slovakia for urban public transport.
Tatra T6A5 is a city tram of Czech production, the production of which was carried out in the years 1991-1998. In the basic version, the total length of the vehicle is 14.7 meters, with a height of 3.165 meters and a width of 2.5 meters. The curb weight of the tram is 18,700 kilograms. The top speed is 65 km / h. In its basic version, the tram provides passengers with 25 seats and 100 standing places. The T6A5 model is one of the products offered by the Czechoslovakian, and now Czech, company founded in 1927 Ceskomoravska Kolben Danek (abbreviated: C. KD). The roots of the presented tram go back to the 1980s, when the CKD plants started to design and manufacture a type of rail vehicle that is as cheap as possible in operation and is dedicated primarily to the Czechoslovak and European markets. Finally, a tram with an angular structure (sometimes called an "iron" for this reason), with large windows and usually three pairs of doors on the right-hand side, was created. Currently, trams of this type are operated only in the Czech Republic and Slovakia in such cities as: Brno, Prague, Ostrava, Bratislava and Ko¹ice.
