Truck Bus

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 container mounted on a truck chassis or a bus with a large open or closed in cargo area.

Truck buses were mainly used by the military, the police anti-riot units, as school buses, and by state owned companies on short routes for employees.

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.
