You can increase the (time)efficiency of your trains by researching breaking force. But even with breaking force fully researched, trains take a while to stop. But there are other ways to get trains to stop fast...

For example: by crashing into an other train on purpose.

That seems rather destructive. Needs a lot of repair packs long term and you can't use any signals with this.

How about using the blueprint printer mod and instead of crashing into a train remove a tile of train track at the right moment to make the train stop?

Use a circuit condition to close a signal, trains then stop on a dime.

Huh? When a signal is reserved then setting it to red with a circuit is ignored till the train has passed. Anything else would be a bug.

Disable all the stations on the train's route. No path found -> Speed becomes 0 instantly. With some clever combinator magic plus a rail signal in read mode that trick should be usable to halt a train in a desired position.

Hmm, you would put 2 stations near each other. First station is disabled, second is the currently scheduled station. Then when the train is right at the first station disable all stations. and next tick enable the first station. The train would stop and then halt at the first station.

But that would be hard to scale. You would need separate stations for every train (both pickup and delivery).

Yea, this only really works on closed loops. Deactivating all stations in the trains list also means you can't put this on a multiple-trains-on-shared-rail scheme, since it'll dead stop -all- trains with those destinations currently in motion. But for niche loops there may be a reason to do this.

This seems to work with a 1-1 train..... but would it work with a 4-8-4 train..... I have seen those things plow through another train with no problem. Or does a sideways train offer more resistance.?

It is intentional! And the trains really do instantly stop if you change a signal right in front of it to red.

Not in my experience. I had a circuit controlled safe crossing that raises a gate and changes approaching signals to red if a player approaches the gate in front of the crossing. Trains tend to blow right through the gates (destroying them in the process without slowing at all) and completely ignore the signal.

Sure you not just raise the gate and change the signal too late? Also you don't need a gate if the signal turns red.
I might need an intersecting rail for the instant stop to happen.

Can you upload a save game demonstrating this behaviour?

So just put a perpendicular rail section in place? Interesting. Will give that a try.
