HST knuckles must be oriented for the direction of movement on both power cars, which direction is correct?

Explanation:
Knuckles are the locking parts of the coupler, and they must present the locking face toward the direction the train is moving so the two halves engage properly as you pull away. When both power cars have their knuckles oriented to face forward, the locking surfaces stay aligned with the mating knuckle, ensuring a solid lock under pull forces and that the release mechanism lines up for safe uncoupling when needed. Misorienting a knuckle would misalign the lock, increase wear, and could lead to unreliable coupling or difficult uncoupling. That’s why facing forward is the correct orientation.
