DT says steam engines wouldn't work on tsw because of nessary cab controls,so what controls would a tsw steam engine need for tsw?
I am not convinced that this is a good reason to not have steam at all. A better reason would be that... given that they have "optimised out" most lighting effects in TSW, and decided against having a decent LOD, and have decided to keep motion blur on wheels... then I suspect that adding large rotating driving wheels with complex drive gear moving at speed, plus particle effects from chimneys, cylinders, valves and whistles.... might be a bit tricky.... That said - they could do 0-4-0 or 0-6-0 drive gear.... 0-6-0 is already in TSW at slow speeds with the Class 08 and Class 09. Regarding controls... well - they managed it in TS1.... basically you need: - a regulator: a bit like a throttle (but not really... but sort of...) - a cut-off valve: that balances against the regulator - a bit like a reverser, or gear... (but, um, not quite..) - a brake: errrm... a brake If you are into multi-tasking, then you could also feed in the coal and water. The XBox controller and PS4 DS4 are adequate to the task.... and there is the keyboard/mouse as well for those that are that way inclined... You obviously need a button for a whistle, and more complex simulation would require you to relieve pressure with the cylinder-koch (sic!).... say, if you have been boiling away without using the energy by not moving for a while, say... at a station stop.... and then there's the injector and blower to push in more steam and air (a bit like a turbo and super-charger in a car). If you can handle the DB BR 155 and the Class 101 DMMU in TSW.... then you'd be well on your way to driving a simulated steam engine. The most important skill is being able to plan well ahead, and understanding how to be economical with the water.
For years now TS has included steam engines that provide a choice between simple and complex controls. I purchased a couple such engines and enjoyed driving them, usually with simple controls, but occasionally daring to take on the complex versions. It seems as though this should work in TSW as well, but perhaps something in its more complex software prohibits it?
