For the love of Alcos (RS-3)

Seems like the other lever is the MOTORING settings...

The two smaller levers on the brakestand are for the sanders. Front and rear.

What three gauges do you think are on the front panel?

After looking at the cab photo after downloading and view at 100%+ size - the three gauges on the forward panel are left (?) [reads 40 - 240], middle is labeled Fuel Pressure, right is labeled Lube Oil Pressure.

Could the one on the left be a temp gauge? That would fit the 40-240 range pretty nicely

I wonder why that note says "Absolutely NO prolonged idling of engine!"

There is a taped on piece of paper indicating that the 'Selector Handle Position' is for controlling series/parallel transition.

The 2 little handles on either side of the automatic brake valve are the Sander Valve, which is the one closest to the camera, and the other one is the Bell Ringer Valve.

I would assume one is for dynamic braking and the other for throttle, but could be wrong, as I am not sure if dynamic braking was a thing on RS3's.

Yes, you could buy an RS-3 with Dyanmic brakes. As I suspected, RS-3s equipped with DBs had extra vent. In the RS-3, the DB would be in the short hood.

Scott, if you want to make a DB equipped RS-3, this should be helpful.

The small slot below the throttle is for the Reverser lever which has been removed.

Hi Folks,

Hey - thank you for all the information - I need to read over it all and check Pete's links in more detail. Marek sent me a bunch as well.

I had no idea that Pete's initial post was so high of a resolution - what a great resource.

Yeah - I thought the reverser was in the slot below the throttle.

I don't think my original source had Dynamic Brakes - so perhaps I just leave the lever off?

Again - I've only taken a cursory look at all the info posted here - rest assured I'll go through it with a fine-tooth comb as time permits.

Did a little mesh work - there always needs to be a tradeoff - I can't capture every curve, nut, and bolt - 3000 polys worth of cab (hasn't been cleaned up) - starting to look closer to the prototype - getting the gist. While I have accurate dimensions for the exterior - everything here is just a swag. If scale looks off - please let me know.

Appreciate the interest.
😉

Regards,
Scott

Hi, Scott. You're doing a great job with the modeling! The only thing I would suggest is related to your weathering. To me, it looks like your weathering is streaked horizontally on both paint schemes. I would suggest streaking it vertically, as gravity would have it. More like the weathering on the IRL pic Shawn posted.

I like the indicator lamps particularly.

Now you need a bunch of these.

Hi.

Thanks - good eye - I'll have to test it out and see if it's worth the effort to redo the base textures - I see what you mean.

Hi Pete,

Hah - yeah. I'll need a bunch on that forward bulkhead. I was thinking about the lamps as I made them - we don't really have any means to light them - no real light - or even a mechanism to switch states with simple textures.

<taps microphone> Ahem... is this thing on? Devs, are you listening? We need more blinken-lights!

Hi Pete,

LOL - yeah - that's probably a big hurdle - a real logic system - so we could do real world startups - like DTG.

Hey - quick question - have you ever figured out snapping to face? There are two face options - but - the snap never seems to go to the desired face. Not as huge deal - as it does snap - then I typically just rotate the object by 90 to get what I want - but an unnecessary step I would think?

For indicator lamps, I use a 2-part multi-material. The first material is unlit and has unlit textures to match, while the second is set to halfbright and has lit textures. Typically, I arrange my lit/unlit parts on the top and bottom half of a single map so that a simple UVW transposition of -.5 can be applied to the lit parts:

I then make 2 copies of whatever needs to be lit, and swap them with a 2-frame animation between lit and unlit:

To examine the details of this implementation, see the 70-tonner and 25-tonner models. This is how the gauge and indicator lighting works.
