Well, I'm no IT specialist, but other freight wagons with bogies have them movable and they work fine even with the high amount of wagons used. Even vanilla wagons with 2x2 wheels have them movable, so I believe if the computer can handle Mashinky at all, it can handle the bogies (check for example the logging wagon Nossinger)
Anyway, your wagons are beautiful even without it,. it just would be more

Thank you!. Regarding independent part and moveble bogeys - yes it's possible, but it will be add more load for hardware due to big quatnity of cargo wagons (much more then passangers wagons) on map. So for reduce load and maintain high fps i'm don't added movable bogeys :)

Beautiful wagons, thank you. Only small detail. Do you think, you might be able to update the bogies to be independent / rotating in the curves? Id would look even nicer. (Don't ask me how, I'm no modeller, but it is possible as "independent part". You would have to reverse engineer the vanilla long passenger wagons for example, or some other mods.

Автору золотой бюст в студию! Но в игре не хватает явно советских вагонов для нефти тех которые короткие и которые удлинённые))
