eli5: multiple train engine orientation

194 views

Live close to railroad tracks constantly see cars being pulled with one engine forward and one backward. The one that really stumped me yesterday, was a train that started with 5 engines in the following orientation: forward, backward, forward, forward, backward

Train engines can run in both directions.
What you observed was either stacking multiple engines to move a really heaving train.
Or moving the engines itself from point A to B for whatever reason, that is done by with one engine active for saving fuel.

The Orientation of the engines doesn’t matter in both of the cases, they are just connected together the way they are set on the rails currently as you can’t turn an train around that easy
