Does the smoke 'chuff' on Trainz?
What do you mean by that? :-?
Does it actually cuff. Not dibble out all the time like most sims.

Depends on which model, the 9F you see there does dependant on where the regulator is, but on the older models like the 4F you get a constant flow of steam. The new models on TC3 all chuff, and have revised engine sounds to work in time with the pistons![]()
Dave, what version were you running the 9F?, TC or TRS2006?
