If feedback on Driver Assist is still being listened on, then it could be added to all steam locomotives released by DTG and future ones. Personally, I find easier to drive engines to operate, like maintaining boiler pressure and etc etc. The only thing on that Driver Assist could be improved on is telling us what buttons to press if it says "add more coal if the engine is working hard". I have no idea on how to shovel the coal faster.
Usually the “R” key is used to change the stokers rate. Some of the more advanced steamers are really challenging were hitting “R” is equal to a shovel full, so the faster you hit “R” the more coal you shovel. All this is covered in the manuals.
