The B-Liner was a diesel-powered bus manufactured by General Motors and added to the fleet of the Birmingham Transit Company in 1960. The design of the interior was created with the participation of executives from the American Transit Association. Features were said to include "lower entrance and exit, fashion-plate interiors, new fluorescent lights, comfortable cloud-soft ride, and picture window visibility."
The exterior styling followed the BTC scheme of white and warm-gray with persimmon red accents.
