Trailer bus

A tractor bus, coach and saddle, respectively Sattelbus called on Cuba Kamelbus, is a hybrid between a truck and a bus. For him, a conventional tractor with a special semi-trailers for the transport of persons combined. Because of their length they have a greater transport capacity as a solo buses, another advantage is the low-floor technology.

The first vehicles of this type were built in the 1930s, for example, the types Bussing and Bussing SS DS. Emerged sporadically including two-storey variants in later years. However, Tractor buses were able to prevail against either the successful bus trailer, nor against the later arisen articulated buses. In addition, since 1 July 1960, the passenger transport in trailers is prohibited in West Germany.

Also a combination of trucks and buses represent the so-called combination buses that can transport goods and people simultaneously.

Tractor buses in the GDR

For the traffic of Wismut beginning of the 1950s were procured 30 buses used truck from the Netherlands. These were built from 1946 to tractor PT42 by Crossley Motors with trailers DAF or Werkspoor. Beginning of the 1960s, the vehicles were worn out. The trailers were in the motor vehicle repair operation ( KRB ) of the bismuth rebuilt and received 52 seats and 28 standing passengers. When tractors were used IFA Z6 used. The vehicles were used until the mid- 1960s in several large companies in the traffic. However, not all procured 30 buses have been retrofitted, part remained in the original configuration in use.

In East Berlin 1953 came a truck with double deck trailers for use. Tractor is derived from the IFA H6 semi truck Z6 IFA Horch factory / Zwickau was used, which was equipped with a 120 -hp 6- cylinder diesel engine of the type EM 6-20. The first set came with a trailer from LOWA Werdau and had the type designation DoS6. 1955, there was a small batch delivery of seven more tractors and trailers, this time the trailers were, however, supplied by wagon Ammendorf. They had a capacity of 38 seats and above 26 below. At standing room 3 were above and 33 offered below. The vehicle length was about 15 feet, so they were the longest double-decker ever used in Berlin. They were used in the main to the line 27 ( S-Bahn station Kaulsdorf -Köpenick - Müggelheim ). A vehicle was delivered to Moscow in 1959. The rest were scrapped in the 1960s. The engine of the tractor -trailer was often viewed in this capacity as too weak. With the same trailers also a trolley bus was put into service in 1955, this was the type designation ES6.

Tractor buses to Cuba

Until the 1980s, the urban bus in Havana was mainly imported from the UK brand buses Leyland. From the Cuban economic crisis, however, resulted in a shortage of foreign exchange, which henceforth was also evident in local public transport in the country. Semi-trailer were in the capital, therefore, to overcome the shortage of buses ( which had to be imported expensive), designed for passenger transport. In general, these were drawn from U.S. tractor.

Because of the shape of the tractor -trailer bus in Havana Camello is called (Spanish for camel ), though you otherwise referred to as an omnibus Guagua in the Spanish- speaking Caribbean and the Canary Islands. The name is due to the " bump " at both ends of the semi-trailer. Originally planned as a temporary, included the Camellos long years of the cityscape of the capital. From tourists like to photograph the vehicle at the " Habaneros " were more likely than an unpopular symbol of economy of scarcity. They were perceived as not very comfortable, and were unklimatisiert usually crowded. They had 58 seats, but often transported up to 400 people. From the year 2005, the Camellos were then gradually replaced by other buses, mostly from the Chinese manufacturer Yutong. In April 2008, the last Camello was decommissioned.

Parallel to the Camellos was built in Cuba in addition to numerous hand acquired conventional buses to semi-trailers.

Tractor buses in South Africa

The South African Railways SAR talked, among other numerous saddle buses. Manufacturers were primarily International and Oshkosh.

Tractor - railbuses

Another special feature were the five Borgward railbuses the Sylt Island Railway, officially referred to as light railcars. This is also based on the semi- principle.

Stoll trolleybuses

Besides the above-mentioned DDR prototype based ES6 also the early trolleybuses after Stoll system on the principle articulated lorry. They all possessed a two-axis drive unit to a single-axis trailer has been set up. Such vehicles were at the beginning of the 20th century at Dresdner heath railway, the railway track lots Poprad - Ótátrafüred, lots of track rail Sibiu and lots of track rail Niederschoeneweide - Johannistal used. However, the principle is not proved.
