It's unplayable.
It's currently impossible to play because the screen blacks out and the controls become erratic, making it unresponsive. Using GeForce NOW on a Chromium-based browser seems to be the only viable way to play it right now.

Can load into main menu but no video playback
First initial minute is white screen where the intro video usually plays. After waiting about a minute, the menu is displayed and can be navigated without any issue. Loading into a "line" is fast and snappy, but when it's done loading a pop-up shows "apiRenderMainWindow()"-error, and that the video cannot be found. Train interior and HUD shows fine, but black video playback and can't drive the train.

protontricks 2111630 d3dcompiler_43 protontricks 2111630 winecfg Add msvcm90.dll, msvcp90.dll, msvcr90.dll (all of them is (native, built-in)) to the library.
Scenery video doesn't play and turns green
After booting, it takes a few minutes with the white screen until the opening screen begins. The opening screen alternates with the menu screen, making it very difficult to see. You need to hold down the ENTER key during this time. If you can reach the menu screen, there are no problems between the menus. When driving, the scenic video does not play and remains green. Operation is possible, 3D signals etc are normal, only the video does not display.
I have managed to get it to work, but the most important thing is that the video does not display. I think it will be working perfectly once the video displays. Testing is now possible with the free trial version, so I hope that GE-Proton will support video encoding processing.

We still can't continue playing, but I was able to get to the title screen.
We still can't continue, but I found a way to avoid the CompileShaderFromFile error and get to the title screen, so I'll write it here. The cause of the CompileShaderFromFile error was the lack of d3dcompiler_43. So first install Protontricks. protontricks 2111630 d3dcompiler_43 or protontricks 2111630 dxvk This will get we to the start of the opening movie. The white screen will continue for about a minute until the opening video and music start.
The opening screen alternates with the menu screen every frame, which is very painful to watch. If you press a key to go to the menu, it crashes.
I hope someone can find a way to get past this.

Game start up quickly. the menu keeps flickering in during the intro. the game is unplayable, since u can only see the inside of the train.
i can see the inside of the train but the outside is just a giant "greenscreen"
Game crashed near the first station
Intro is playing while menu keeps flickering in

The same errors as normal Proton.
Intro is flickering and main menu stays black but is interactable.

Still nothing works
Waited a few months before testing again to give the Proton and/or JR East Train Devs the time to fix things, but still nothing works.
Errors are unchanged, it crashes with the exact same errors at the same position.

Still broken
Latest Updates of the game didn't change anything. Latest Update of Steam neither

Crashes instantly at start
Nothing works

Infinite hang on loading screen
tried installing allcodecs and vcrun to no avail
intro highly distorted and crashes after a few seconds, skipping the intro leads to a totally black menu that does however fully work despite not displaying anything, however attempting to start a route the game gets stuck on the loading screen
If you really want to play it on The Deck, you have to stream it from you PC. No way to run it natively on the Deck.
Displays a bunch of errors when starting, then just displays a black screen. Sound does play though.
Shows loading screen but nothing more
It just crashes with CompileShaderFromFile error

The splash screen shows, the main music menu plays but the menu is entirely black. Either using Proton 7.0-4 or Experimental.

Shows error then crashes
Game shows the splash screen then a couple of failed assertions:
MLRenderState_PC.cpp line 1027 : ERROR : (0) FAILED CompileShaderFromFile Error
MLRenderState_PC.cpp line 358 : ERROR : (0) FAILED CompileShaderFromFile 80004005
If these are ignored the game loads for a second and then goes to a black screen. You can hear the main menu music but nothing is visible on the screen.
Also tried using GE-Proton7-35 with no success
