Switching with loco both ends of train

[Engfanuk]

On my layout plans I'm thinking of ditching the runaround after settling on a New Jersey CSAO theme and seeing photos of trains running with locomotives both ends of train to handle trailing and facing switches. However I'm unclear how this is handled proto typically.

I can imagine a train switching a facing point would run past it, disconnect the forward locomotive, the rear locomotive would reverse past the switch and then shove the train into the spur. I'd like to check that with the forum.

Thanks,

Steve.
