      Andy "How many " engines do you have??

      Sean,

      I think you just wanted to see if an old man can still count that high...  :)

      I have 37 that can be used for Operations..   Of that 37, 3 are RDC-3's, 3 are RDC-1's, one Shay, and One 4-6-0 with a BBT drive..

      The rest are all Diesels..  I wanted to have enough engines available for folks to run during Ops sessions, if they did not have their own engines..

      I still have a few that have not been set up for battery yet..

      The other break down is the Santa Fe 50' box car with a serious truck issue

      and do you have a set of GW leaseable locos for breakdowns? Nice set Andy. I'd have used pair, but with this crowd.

      Breakdowns??   What are those???   hehehe

       

       

      Something your son had when you spent his college fund on YOUR  RR

      There's a good majority of leased locos during Ops sessions, but no GW...

    • This past weekend I added a new set of EVWR locos to the stable..

       These units will run the unit coal train..    The units modeled were ex-UP SD-40-2's, that were rebuilt and painted for Evansville Western RR for use on their coal trains..

       

       

       

       

       

      Shortly, they will be completed for service with batteries and Revo controls..  Hope to make the inaugural run during the May 2018 Ops session...

    • I'd check with RCS of New England  Don Sweet:  https://www.rcsofne.com/

       

      Many battery power conversions are made by ripping out everything they don't want, and smoke is rarely used in battery since it can consume as much as the motive power needs.

    • I will keep an eye out for one of those.

    • So you have the stock smoke unit, the old style with the crummy motor:

       

       

      You might want to just put a better unit in it, the more modern Aristo unit:

    • I have decided to abandon the smoke plan for now.  It turns out that my fan motor is very noisy.  So I've buttoned the engine up.  

       

      Here's the final interior arrangment:

       

      And a custom switch plate and charging jack under the stock switch cover.  The switches are power for the decoder, power for sound and accessories, and the P8 Volume control.

    • That will be a fun locomotive to operate , great job .

    • Some more progress on the RS-3.  I've installed LEDs for the headlights and number boards, and a battery under the short hood.  

       

      This is a rack that I 3D printed to hold the AirWire G3, Phoenix P8, and a 60x40 protoboard.  The protoboard will have an Arduino Pro Mini on it to control the couplers, lighting, and smoke - connected to the G3's DCC output.

      I wonder if the first gear envisioned for the driveshaft was to be metal, so it could handle a setscrew?

      I'll have to ask when I take it back - don't think I ever saw the original gear.  The new one is easily large enough to take a pin - maybe drill across the flat from one side of the gear to the other, and cut the pin short enough to not interfere.

    • AirWire has BEMF sensing (I assume) for their cruise control, but it is not externally available.   Since I plan to use this as a switcher with short trains, most discrepancy between commanded an actual speed will be the result of the momentum setting, which is predictable. So I think I can cobble something realistic together using DCC.  I’ll see what I can come up with.

    • If you don't have BEMF sensing, you could sense the speed of the motor with a tach, and then use the difference between the commanded speed and the actual speed to figure out load.

    • Eric,

       

      the real thing only really smokes until the turbo kicks in. but of course no one has come up with the magic black smoke that is repeatable yet.

       

      years ago in model railroader there was a fiction piece on real black smoke for our models.

    • Thanks.  That's exactly what I needed to know.  So actually modulate the fan speed, as opposed to a binary on/off.  I was going to just use the DCC speed packets for control, but BEMF is another option.  

    • February 12, 2018 4:53 PM EST
    • Not modulating the heater and having slow speed will equal melted plastic.

       

      The right operation is to sense load and motor speed, and kick up the fan speed and heater both under higher speed and load. Note I mean the motor speed the prototype would be using, and so you want to incorporate the idea of "notches" in your electronics. I'd use BEMF to sense load, and motor rpm.

      p.s. figure out black smoke like a real AlCO and you will have permanent hero status!
