RS-1 Development

[evafan002]

Maybe it's just an old pump that someone dumped on the deck and it rusted there until it fused with the engine.

too shiny for that mate

I would have bet it was the toilet on the International Space Station.

Oh well, there goes my dream of being any kind of Engineer!

Rick,
I have reason to believe that the valve in your picture may involve the ATS or Cab Signal system on the New Haven RS1. Unfortunately, I cannot find any resources on the web to substantiate this claim...

The strange valve in your photo is not standard RS1 equipment. Search the web for photos of RS1's & it is difficult to locate photos of locomotives with this strange valve mounted ahead of the cab.

I have seen a valve like this before on an ex-Long Island RS3. The locomotive was built with a steam generator for passenger service & once had cab signals. I think the valve in your photo controlled the air brake part of the cab signal system, stopping the train if it passed a red signal.

About 20 years ago an engineer told me what the valve was used for but that memory is pretty hazy & I wish I could find a resource to back it up.

The regular brake equipment resides under the cab floor on all the locomotives I have encountered.

Great work on the model!!! I'm confident it will be excellent when released.

Thanks for the input, Tyler. Scanning through the RS-1 photo collection at RailPictures.net I see the "mystery valve" isn't always there, but it does appear, in one variation or another, on locos bearing the liveries of GM&O, DS&A, GT, GMRy and probably others.

I added some modified triple-valve geometry to the model, mostly because that's the way I wanted it. However, I've found that the locomotive's performance in the sim is identical with and without it!

Hey,
I'm entirely new here but after noticing that an RS-1 was under development I figured I should step in since I'm an absolute ALCO-holic and spend a good most of my time around an RS-1 and an S-1. I just wanted to point out for right now that the spaghetti-pipes next to the cab ARE, In-fact, triple-valves, for when MU-ing or trailing, thus why most of them don't have it, very few railroads ordered MU-able RS-1's, though some were re-fitted later in life. Also the nit-picking has to kick in so let me say in the kindest way possible, your cab is backwards, though only the windows over the long and short hood. Alright thanks, hopefully I can answer any questions you have about the locomotive inside or out. I've been waiting to see this or something similar happen in Railworks. A friend of mine and myself recently worked on an RS-1 for the "Trainz" simulator.

Thanks for your observations, Chris. I was going by a drawing, but comparing it to photos reveals it to be in error. As far as I can tell, the bottom of the left-rear window is about even with the mid-point of the side windows; the bottoms of all the other corner windows are even with the bottoms of the side windows; the center posts between the front and rear windows are about the same width; the right-side windows are toward the forward part of the cab with the left-side windows are toward the rear. Is that consistent with your understanding?

Being a short line, the RW&A typically doesn't use MU lashups; however, their RS-1s, being hand-me-downs, were all supplied with the external triple valve already installed.

What's the U-bend pipe for?

Also, in a railroad fan forum somebody wrote that the tank directly beneath the cab floor is for fuel and the oval one under the frame is for water. Tell me that's nonsense and it's the other way around!

[CMRR401]

I'm posting this from school and thus cannot give specifics currently, I'm not aware of the specifics of the window layouts off the top of my head, nor the use of the U-bend pipe, I believe it had to do with the poppet valve... I know from your pictures that the windows over the long and short hood are correct, but need to be reversed. Also the "fireman's" side of the cab, so to speak, has a three-section sliding window, Instead of the two seperate panes on the drivers side.

And to allow you to relax, -BOTH- tanks are fuel tanks. Reasoning for this being that the S series design already had the fuel tank under the cab floor, which carried over to the RS-1. However, due to the extended frame and entirely different purpose of the RS-1, space under the frame was used for a second fuel tank as well as the battery box, whereas on the S series there was only room for the battery box, basically doubling the fuel capacity and range of the locomotive.

P.S. I'll get back to you about the pipes later this afternoon.......interested in what horn(s) you're planning on using....

[BNSFdude]

Boy, I hope it's an A-200. BWOOOOOOOOOOOOOOOOOOOOOOOOOOOOOONK.

[ricksan]

I have nothing to do with the audio. More on that later.

[BNSFdude]

I spoke with the LSRM again, they said they may be able to run the 101 but not through the full throttle range, I should be able to work with that I can get too.

I was shocked to read a few weeks ago that they did indeed put the fuel under the crew, and the water for steam generators under the center frame.
They moved it for the same reason they eventually removed fuel tanks from pickup cabs.
I think that was only on versions of the RS-1.

Looking Forward to this and the Route! I need a nice line to run the Little 844 on!
