I'm also wondering. I saw co-op and said "okay... Now I'm interested". But there are no videos or reviews of it.

Co-op works with two people (I don't know what the limit is) interacting with the same map. All players control all trains and signals. On large maps it helps be two people.

Does this support steam remoteplay together by any luck ?

Coop works very similarly to single player, except you have your own screen to look at.
You do however get to see where the other player's mouse cursor is, making it easy to point to stuff and talk about it.
You both have control over the passage of time (From pause to how fast it moves)

In other words, if you found the singleplayer game stressful, and you ran out of APM (Actions Per Minute), then two players will give you a significant boost.

Only drawback to Coop is that the early game is painfully slow until you can get a double track setup and a few trains going.
That part is perfect for SP, but a bit too boring in multiplayer.

Its fun but I would not buy it for co-op as of now, had a lot of desync and connection issues, like 4+ reconnects each play session.

We have some bugs reported regarding this - should be resolved today.

However, without reporting & providing logs, we will not move anywhere further. Multiplayer was tested in unstable branch for a couple of weeks & the players reported it works well by the end of the testing period.

Then, for instance, one error surfaced that happens only when the computers participating in multiplayer use different culture settings so that some have decimal point & some have decimal digit in the sensor synthetic names. This one is already resolved.

So, if you encounter a desync, please report a bug & include the Player.logs & also the multiplayer-server.log & multiplayer-client.log for us to nail the bug down.
