This is a core engine issue - so I didn't know whether to stick it here on in multiplayer, as it applies to both. I ended up sticking it here, even though it's pretty quiet here compared to the multiplayer section. (As an aside, I think maybe this section should be renamed to "General Sim", rather then single player, as SP is very limited for the time being and no one seems to be playing it 🙂)
But in any case... Cab sway physics and head movement... it is... to put it mildly... unsatisfactory. The EP07/08 and variants seem to have a scripted sway that just rocks the cab from side to side mechanically with no regard to the track - neither bends nor speed seem to have any effect. Switches trigger a similarly mechanical up and down motion that never varies. The newer trains - the Pendolino and the Elf - cab sway is nonexistant, even the primitive script kind that is in the EP07s, and switches only trigger sound.
IMO, this is the one big gripe I have with this sim as it stands. Everything else I'm really enjoying. The gameplay (multiplayer!), the route, the look, the overall train physics and sounds are all great. But this train-glued-to-track feeling is very distracting and takes me out of the realism often, especially with the ED250. Flying 200kph down the track feels exactly the same as going 20, and it is just boring this way. The other thing that bothers me, the lack of raildriver support, I'm not even worried about - as it is clearly coming soon, being on the todo list that was released a while ago. Cab sway and head movement physics are nowhere to be found on that list and that worries me. Cab sway is the one thing that still makes me even consider firing up that other sim (that shall not be named), occasionally 😉
Is there any info on the subject from the devs that I might not be aware of? Is this something that is even being worked on? I'd love to know.
