Fairly simple question, if not why not? Seems weird that DTG flagship game wouldn’t have the best available simugraph available unless it wasn’t compatible with UE4.
It's probably not compatible with UE4. Metro Rivals is a UE5 game, and they brought over TSW's Simugraph to Metro Rivals when developing it, so any upgrades they made to Simugraph after moving it would have been made in UE5.
Why is Metro Rivals even getting Simugraph? It's an arcade racing game. I don't think 6 year-old Timmy is going to care about correct signalling, when he usually drives a Toyota Supra at 250mph in Forza. Kids want fun and replay value, not boring real-world stuff and 300 page instruction manuals.
Ya'll this game is a test bed for UE5/Simugraph for the next train sim game. That's the entire point of its existence. To answer OP's question, how many features have been backported from TSW to TSC? I haven't played TSC in years but my guess is none.
Matt may correct me, but I believe he already answered that - porting TSW to Ue5 is more work than building from scratch, but the conundrum is existing DLCs
Also, this is a retail product that will sell between £29.99 - £69.99 depending on what mood DTG are in on release week. Arcade racing like Wipeout? Semi-realistic like Derail Valley? Train Sim World with disco lights? Training tool for DTG staff? Nobody knows what the heck this thing is supposed to be, and that must be one hell of a headache for the DTG sales & marketing department who are expected to push this thing to customers.
Um, Unreal Engine is a graphics engine, and so Simugraph, a physics engine, has little to nothing to do with it.
Here are two examples of train games using UE5. Did you find improvements big enough to make your eyes pop out? SubwaySim Hamburg on Steam https://share.google/4bJfZNjJeniDsNmfx https://share.google/m0qrwd2ZemPnyeDxi

They mentioned it will also use Simugraph, so presumably that will be receiving updates as well to play nicely with UE5.
