RS-1 Cab

I like the idea of adding control lags, assuming that's possible.

It's very easy. All you have to do is introduce another, intermediate, control variable for the gauge value that you manipulate in the LUA script and, after an appropriate delay, assign to the other control variable that governs the display on the gauge. The other way is to introduce the delay on the "input" side. For example, in the Connie, I have a control variable called "RegulatorLever" that is connected to the actual throttle that you move with the mouse and/or keyboard. When it's moved (as detected in the function "OnControlValueChange"), I record its value and start a rolling countdown that gets tested in each call to "Update" - when the countdown reaches zero, I write the value that "RegulatorLever" had at the start of the countdown into the actual control variable "Regulator" that the core code recognizes as the regulator. The countdown is enough to simulate a 1-second lag. It's a rolling countdown because values of "RegulatorLever" are in fact recorded in the next entry in a cyclic buffer, so that the value written into "Regulator" is taken from the nth previous entry.

If you need some examples, or just want me to help you write the LUA, drop me a pm and we can sort it out.

P.S. The cab looks fantastic.

Mike: Conceptually, that's more or less how I thought it might be done. Script uses a custom control as the surrogate for a default control. User adjusts the custom control (thinking he's adjusting the default control), script does some calculations, script assigns a new value to the default control.

Thanks for you offer to help with the script. I'll make contact after the bulk of the visual work on the cab is done.

Yep, that's exactly right.

OK, and hopefully by then I'll have finished 844 (I'm scripting several surrogate cab controls right now).

Gah, this is what I get for sleeping in. Um, just a word of advice, before you go off modeling series parallel switches and what not, this whole "Gears" (so to speak) system is on one, and only one, RS-1, that I know of, where the reverser has been notched into three separate positions, both forward and reverse. I just wanted to make it clear that not all RS-1's behave in this manner and thus modeling it as a "Gear" Instead of a plain old reverser isn't necessary, unless you want to make a one off model of CMRR #400.

From what I've been able to determine, several, if not all, RS-1s were equipped with series-shunt-parallel switches. All the cab photos I've seen (and admittedly it's a small sample) show either a rotary selector switch, or toggle switches.

The operation of the rotary selector switch is more apparent to me now having read Chris's post: it has series-shunt-parallel switching functions for both the forward and reverse directions incorporated into a single control. In the other style, a separate reverse lever (mounted on the top of the control console) is used.

And again, this kind of an arrangement shouldn't be too surprising. It's easy to imagine that this early ALCo-GE diesel-electric borrowed technology from even earlier locomotive designs, including steam.

I should have the cab pretty well complete by this weekend. Check back here for screen shots.

Amazing work Rick.

Here's the latest.

Visually, this is your cab. Basic (default) control functions are in and working. The specialty scripted controls are TBD.

Pull the horn cord by the handle and on the way down the upper part of the cord goes taut, while the lower part sags.

Anybody know how the bell works? Some RS-1s had a bell mounted on the long hood, but in many photos you don't see a bell. Where is it and what rings it?

[buzz456]

Very nice.

[mrennie]

Beautifully done.

[Chacal]

Insanely beautiful.
Can't wait to buy this, too bad for all those newfangled GP40-2s, GP50s, GP60s, this is what I want.

Looks great, in fact, I was in the cab of one today!

[NYWhiskey]

I feel like I'm standing in the cab again.

I would put the bell on the long hood similar to Green Mountain 405. I find it looks sharp! Amazing work by the way, can't wait to run it!!!!

A lot of them did this, including the DSS&A, which this route reminds me of a lot.
