Bay Area Rapid Transit (BART) Practice Exam 2026 - Free BART Practice Questions and Study Guide

The correct scenario where the maximum speed is limited to 2 MPH is during the operation while in the Car Wash. This restriction is in place to ensure the safety of both the equipment and personnel. The Car Wash area is designed for maintenance and cleaning of the trains, requiring very slow speeds to prevent any potential accidents or damage to the trains or the washing equipment.

In other contexts, such as yard tracks or the shop area, while trains may also move at reduced speeds, they are typically not limited as strictly to 2 MPH. The mainline tracks, on the other hand, allow for significantly higher speeds as they are designed for regular transit operations. Thus, the Car Wash represents a very controlled environment where safety is prioritized through reduced speed limits.
