Coach type 401 was built of high quality ABS in 2001, by the BricWorx Company of Portland, Oregon. It is 18 studs long, 6 studs wide, and 20 plates tall. This coach sets on top of four wheels (two fixed axles) connected with tension rods for a comfortable ride.

This coach, the oldest of the BricWorx coach consist, has been design to be fully reproducible. It features trellised vestibule balconies and arched entryways on both ends of the coach. The ten closely spaced windows provide ample interior light. As with all coaches in the 400 series it is available in custom color schemes straight from the foundry.

Coach type 401 has been nicknamed "Lydia Ann" in honor of the wife of a BricWorx founding member.
