what it says on the title :D
Indeed, because it moving backward :)
You're inside that locomotive, for which this is "backward"

Except i am not in the traind and speed is negative in both directions

Internally the train has front and back and the speed specifies witch direction it moves, so this is not a bug.

Also I'd like to use this opportunity and ask a bit of an OT question that barely deserves it's own thread; when you have a train made up of multiple engines, why does only the one in the lead actually work, towing the other engines as dead weight? In real life (and OpenTTD), all engines in a train contribute equally.

/and also, why do manually driven engines go slower in reverse? Forwards, backwards, it's all the same for the locomotive, it's not a car - unless there's something about game design that I'm not getting, there's no reason for it to go slower in reverse.

The should work if they have the right direction, if they don't work it is a bug.

Hm, it was probably just made this way to motivate players to build the in the reasonable direction, so it looks better :)

Oh, so if I get it right, they all need to face forward? Welp, as I mentioned in the other part of my post, locomotives don't really have a "front" or "back", even the ones with a cab facing only one direction, like Factorio engines or real life Pendolino - their gearboxes are bidirectional and allow them to contribute equally regardless of their orientation. In fact, the aforementioned Pendolino also utilizes motor cars that aren't locomotives at all, yet provide additional power for the train. I don't think locomotives are (or have ever been) ever put in a train for anything but helping with rolling the train - unless they're broken in some way. Even most steam locomotives can push/pull a train, and even while facing the other direction, as primitive as they are!

Here's a gif I've made, as seen on Facepunch. Notice the double-headed train and how both of it's engines work no matter which direction it goes.

Hmm, yes, it makes sense to nudge players in the right direction, or shall I say their trains? :lol: But actually trains can operate with only one engine on the rear end pushing the whole thing from behind, sorta going "backwards" all the way, although usually not for long distances due to bad signal visibility (mostly utilized by "switcher" type locomotives pushing series of railcars at hubs, forming trains) - but for manually driven trains this should be okay. What's worse though, it might later become an issue, I believe sooner or later vehicles will have to be manufactured in a special way (e.g. depots) so they can't be carried around as items, and when that happens, you won't be able to simply pick it up and place it facing the other direction.

EDIT: Beautiful switcher footage

Welp, silly me, going full OT here. I should have really just made a full thread in the ideas section.

Some OT comment, maybe somehow useful.

There is a big difference: OpenTTD has train stations. Factorio has train stops. This difference is important, because the first is a part of the track, the second is a point with a direction.

https://forums.factorio.com/wiki/inde ... Train_stop

More creativity: you can place two train stops in different direction, but with the same name, to create a "train station-like thing" as in OpenTTD. :)

Not exactly. Speed of moving in different direction depends of locomotive running gear construction. There exist a lots of locomotive models. Some of them cant go backward at all.

I wonder how many of those are diesel-electric.

None I suppose?
