- Trailer bus
A Trailer bus or articulated trailer bus is a
bus formed out of a bus bodiedsemi-trailer pulled by a conventionaltractor unit in the same way as a conventional articulatedSemi-trailer truck .Trailer buses are usually pulled by a conventional truck from various truck manufacturers, while others have larger space cabs. Trailer bus bodies are built by various local builders.
Early trailer bus designs emerged as early as 1924, with a large amount seeing service in the post war years. Several trailer buses continued in service in more remote and rugged areas such as
South Africa , possibly due to the terrain, and availability of specialist bus builders as opposed to truck dealers and basic body builders.An early Trailer bus was designed in Amsterdam in the 1920s as bus designs got longer. As a solution to possible grounding hazards on humped bridges 3 prototypes were built in 1924, but proved to be problematic and later converted to rigid bodies in 1927 [ [http://homepages.cwi.nl/~dik/english/public_transport/odds_and_ends/bus.html An early articulated bus from Amsterdam] ] .
