A combination bus, also called a truck bus or shift bus, is a purpose-built truck with a "passenger container" fulfilling the role of a bus. Such vehicles used to be common in Communist Bloc countries and in developing countries. Alternative combination buses can be a passenger/cargo module/container mounted on a truck chassis or a bus with a large open or closed in cargo area.
The concept and functions of combination bus differs significantly from brucks (< bus + truck) used by Great Northern Railway in Montana 1951–1971 as well as from "passenger-freighters" introduced by Western Australian Government Railway in 1949. These vehicles were built to combine goods and passenger transport in circumstances where passenger transport was required but couldn't be profitable as such. These approaches were also known in Scandinavia (as "seka-auto" in Finnish and as "kombi-buss" in Swedish). They were used on some countryside routes until early 1970s.
Combination buses are built by installing a complete box body equipped for transporting people onto a truck chassis. The body is independent and separate from the driver. There is usually no passage between the cab and box body but there is usually an intercom system. The body is equipped with windows, a separate internal lighting and heating and/or air conditioning systems. Related bodies are different types of mobile workshops or specialized military superstructure. Passenger comfort is generally minimal.
Due to the minimum of comfort provided by the combination bus, they are suitable for transport over short distances only. Specifically, the distribution of workers in large workplaces under the open sky such as a large construction site, agricultural labor, quarries or surface mines. Often these vehicles built on chassis off-road vehicles. These vehicles are encountered as well as the intervention of different cars of police, commandos and anti-terrorism units.
