The main advantage of the B-Train configuration is its inherent stability when compared to most other twin trailer combinations and it is this feature above all else that has ensured its continued development and global acceptance. Although known as a B-Train in many countries, this particular twin trailer combination is also known by the term Interlink in Southern Africa and as a B-Double in Australia. The B-Train principle has been exploited to its full potential in Australia where new configurations such as B-Triples, Double-B-Doubles and 2AB Quads are now commonplace.
