What I’ve found to work is a short block at the end. This is used to stop the loco. But is the staging ONLY used in one direction? If it is usable going either way, you have to mirror the pattern of blocks. But the logic would be for when the whole track is empty, enter and go as slow as needed to be able to stop when hitting that end stopping block.

?

Next, is the end of the train detected? Resistors on wheels, lit caboose, lit FRED, something. If so, the logic for putting a second train into staging would be slow but watch for the turnout to become unoccupied. That’s what is used to stop a second train into a staging track.

?

Now after the first train has left staging, the logic becomes like the original one train into staging and you advance the 2^nd train slow until it gets to the stopping block.

?

If you can’t detect the end of the train, it is still possible but more complicated.
