Which statement describes the A Train configuration?

• A. It has an additional articulation point
• B. It has a self-steering axle
• C. It uses only one pintle hitch
• D. It does not use an independent converter

Answer: (A)

An A Train configuration is defined by having an extra articulation point between trailers created by using a converter dolly to connect a second trailer to the first. That added joint is the defining feature, so describing it as having an additional articulation point best matches what an A Train is. The other statements don’t capture this setup: a self-steering axle isn’t what defines an A Train, a pintle hitch alone doesn’t describe the configuration, and an A Train does use a converter dolly to link the trailers, not omit one.
