What must be done when coupling a D car Y end to an E car?

Unlock the end door

Lock the end door

When coupling a D car's Y end to an E car, it is essential to lock the end door to ensure a secure and reliable connection between the two cars. Locking the end door prevents any potential risk of the door opening while the train is in motion, which is crucial for passenger safety and the structural integrity of the train setup.

A locked end door also helps maintain proper ventilation and climate control within the train cars and reduces the risk of leakage of any substances between the two cars. This practice is foundational in train operations to ensure that all connections are robust and secure, allowing for safe transport across the transit system.

Ensuring the end door is locked also provides an additional layer of readiness and operational safety, meeting the standards mandated by BART for the operation of their trains.
