Any REAL Old-Timers Out There?

I am building (have now built, pretty much) a 1921 Mack railbus for Trainz. I am now at the point of creating the cab details - and certain questions arise.

My working drawings include a layout of the controls, which include throttle, spark advance, reverser, and service brake (handle). The large "steering wheel" in the middle is, of course, the hand brake. I'm assuming this works pretty much like a Model T, which means the throttle lever (one side of the hand brake column) and spark (lever on the other side) start out all the way back and move forward (not synchronously) to accelerate.

The reversing lever is fortunate - that feature can be treated like a diesel (the Model T had a reversing *pedal*). Motion of the throttle and spark levers, though, is tricky: if it's like a Model T (from brief research) you put the spark where the motor ran smoothest for the present throttle, speed, grade, etc., not necessarily at once but when you had time to mess with it. It was only fully retarded when cranking (this prototype appears to lack a crank, might even have had an automatic starter!!) but I'd like to do at least a little something for this effect.

So... is there any way to have *two* throttle levers (one of which will actually be the spark advance) which move at different rates and in opposite directions? I can, of course, try simply having two in the config file, pointed at different meshes. Does this make sense, for those who have driven early Mack trucks?

Finally, the driver's station has three pull-down curtains, presumably to cut down on glare at night, avoid distractions, and give the passengers a little privacy. How should these be handled? They should be down at night, I'd think, and on long stretches between stations... any Greyhound drivers in the audience? They could be made to respond to the pantograph controls, since the prototype has no windshield wipers.
 
I think I'd leave the spark advance as a static element OR a "dummy" lever, since there's no way to model spark advance in the game.

On the other hand, it might be possible with some clever scripting to animate the lever - but it would still be "random" movement.
 
It's possible to have two throttle levers that move together. Check out the interior on skipper1945's Maunsell Shunter. On this loco, one lever rotates anti-clockwise (counter-clockwise) and the other moves clockwise. Having them move at different rates should also be possible. It might be possible to copy and modify the config setup from that interior for yours.

Blinds could probably be achieved as animated levers, although they would only be able to be moved in Cab mode. Like you said, having these as a pantograph is also an option.

And if you wanted/needed them visible from the exterior as well, you could try the 'outside-visible-from-cabin' and 'cabin-visible-from-outside' tags, although these do require the cab to be very accurately positioned and proportioned.

Hi,
For this last bit I would suggest the front curtain and the drivers side curtain would be used in place of modern sun visors and if there is a rear curtain it would be to cut down glare from the passenger compartment. Modern busses now dim or switch of lights in the passenger compartment to cut down glare.

Thanks!

Thanks for all the help and advice. Since the prototype appears to lack a speedometer (with top speed of 45mph and a conductor with a good pocket watch, do you really need one? not to mention the HUD) I think I'll make the spark advance lever a "speedometer" which will cause it to advance more or less in time to engine effort but not synchronous with the throttle.

There are three curtains because the driver is in the middle (approximately - he's offset a bit to the left because seating is 2-3 and he's aligned with the aisle). Panto controls it is. (I vaguely recall riding on a conveyance where curtains were drawn to close off the driver/pilot area from the passengers, but can't remember if this was a bus or a local airliner. Sometime in the last century, it was.)

The setup will, indeed, be outside-visible-from-inside - the only meshes in the "interior" asset will be the animated levers, wheels, etc.. As in my last two locos, the driver figure will be scripted invisible in cab views so interior cameras can look out from his position without interference.
