I would like to see Steam trains in TSW and as in real life keep the Firemans job and the driver's jobs separate, being able to choose and to focus on driving or firing would give a more realistic experience, working with the A.I (or another player when multiplayer comes out) to get the very best out of a steam loco. perhaps the fireman's HUD instead of showing speed and signal information could show the distance to the next gradient change, detailed information on boiler pressure and fire mass etc. that changes colour from green to yellow/red to show when the ideal is being achieved.
