The first buses of 700 series were produced during the 1970s. These were only functional samples and prototypes, which were designed for different tests. The very first bus from 700 series became functional sample of intercity bus Karosa C 733 in 1973. Serial production of 700 series begin in 1981. The first representative was Karosa C 734. This was followed by Karosa B 731, B 732, intercity bus C 735 and long distance touring types LC 735 and LC 736. Also manufactured were articulated vehicles of the type C 744 and B 741. In the early 90s, a coach with a raised floor was developed that was marked as Karosa LC 737 and LC 757. In 1996 that was replaced with an upgraded 900 series and production of buses 700 series was finally completed a year later. A total of 37,166 of buses 700 and 800 was made. The buses were sold in addition to Czechoslovakia and other markets. Probably most of them were exported to the Russia, where was even in 2001 built a statue to Karosa C 734. To Russia were exported and buses known as 800 series, which were based on a 700 series.
Designation
For new buses of Karosa 700 series, before number were one or two letters.
Letter: car type - B, C, LC
First figure: 7 - stands in the segment numbering bus Karosa, however, there has been a shift in meaning and thus marked the first digit '7' 0s, when the bus was designed and constructed
Second figure: the length of the bus - 3 = 11 m, 4 = 17 m, 12 m = 5
Third digit:
* Vehicles B "1" model B 731 originally marked the category B1 bus, later in the development of type B 732 marked the third digit type of gearbox
* LC vehicles: numbers 5, 6 or 7 indicate the level of comfort
* Doors: 1 door, 2 door or 3 doors or 2 doors, 3 doors or 4 doors
Construction
Like their predecessors, Š series, 700 series buses were built using prefabricated buildings. This technology consists in the production of six separate panels to separate welding lines, which were then surface treated and assembled together. A significant change was the production of frames, hips and roof from industrially produced hollow. On the previous row with these parts were molded parts. This solution nowadays makes easier repairs after accidents. Compared to Karosa Š series, which had engine between the wheels, 700 series had engine and transmission stored behind the rear axle. 700 series was developed by engineers Ivan Mervart, Josef Nalezenec and Ladislav Klimeš and designed by Jan Tatoušek and Zdeněk Rosák.
Special buses
Some buses of 700 series were adapted directly from the factory for special purposes. It is worth mentioning buses for transporting prisoners, measuring vehicle for 'Electric companies' or bus for the town library in Prague. For the production of these buses was responsible for first development workshop, later, since 1991, custom workshop. Some buses of 700 series have been produced for the customer special design.
