Artdink are an extremely bad developer that clearly only cares about its Japanese market, and make zero effort for the English language version. The vast majority of trains are missing, as well as other content that exists in the Japanese version but is stripped out for the English version. From Atrain 9 v3.0, 4.0, and now 5.0, there is very little difference, and as of right now the game struggles to even launch without first lowering all the graphical options to low because Artdink couldn't be bothered future proofing this game despite the fact they just released a DLC for it.

Chances are none of the issues with this game or franchise will ever be resolved, because as I said Artdink have shown time and time again that they simply don't care about the English language version at all. Avoid this game, it has some really nice unique features, but they are buried under a trashy developer.
