The term “A-Train” refers to a type of truck configuration where a truck tractor pulls multiple trailers connected by A-dollies. An A-dolly is a type of converter dolly that has an A-shaped frame, allowing the connection of several trailers in a series.
In an A-Train setup:
- The truck tractor is the front unit that provides the motive power.
- A-dollies are used to connect the trailers, providing additional support and enabling the smooth articulation of the train.
- Trailers are connected in a sequence, making the overall length of the combination significantly longer.
This configuration is often used in freight transport to maximize cargo capacity and efficiency, especially on long-haul routes.
