    • Just a question on the RailPro systems, since I want to install the RailPro into an LGB #50 switcher and RailPro has no sounds for that engine, but Tsunami does can I get that sound reordered online, or can I go elsewhere to get it. I'm new to RailPro or Airwire control and I have not purchases a system yet for my G scale engines. I do have DCC in my Blackstone HOn3 engines on my layout, so I have a little idea what is going on, but not much, so I'm asking these questions. It looks like I can purchase a module to plug into my computer from RailPro which will allow me to down load sounds from other sources, but still sorta vague on just exactly how this works.  If you could point me in the right direction on this it would be very much appreciated.

    • I have just used the standard Kadee couplers and off the shelf servo and tie a jewelery chain between these.  The g Guage Kadee coupler can have a screw drilled into the knuckle to hold the chain.  This allows any Kadee off the shelf to be remote controlled, you do not need to stay with Kadees one type of uncoupler.

    • Hi Jim, I am not familiar with the Kadee servo control. However, RailPro does not offer servos start and stop settings.  It is a linear output to run small motors.

      I can tell you that you can use the Phoenix solenoid couplers without any driver board.  Just wire one brown wires to the output and the other brown to +5v. or +V. If +V is to much voltage the RailPro gives a output error. I use diodes to get down to 12-14v for a quick fix.

      After having successfully installed RailPro in Ric’s Evil Twins, I got the bug for converting one of my AirWire installs to RailPro. However, I’ve got Kadee RC couplers on all of my engines and I’m curious if there is a way to control the couplers with RailPro?

      I few years back I made a clone of the Kadee coupler and used a Sparkfun servo trigger https://www.sparkfun.com/products/13118 to actuate it with RailPro.   Ring Engineering helped me with the wiring.

    • I'm a little late to the party, but I've got Soundtraxx Tsunami decoders in both of my railcars. They're the 1-amp version which is plenty. Soundtraxx introduced the Tsunami2 decoders a few years ago, so you can usually find the older Tsunamis going pretty inexpensively, like for $50 or so. For the railtruck sounds, there's no advantage of the Tsu2 over the older Tsunamis.

    • Free free to contact me about how you want to customize the decoder, I have been doing Zimo decoders for over 10 years for Trainli.

    • I use the Zimo MX645 on my LGB rail truck, and I pull several cars.  Wire version is $85 (1.2 amps) and P22 version is $100 (1.8 amps).

      I added a Kadee coupler and 'chained' it to a servo and can do remote uncoupling.

      Remote volume control is also on these decoders.

      Specs are 3 watt audio, can operate 2 servos, can witstand 2.5 amp surge, more than 40 volt surge. 

      This is an HO decoder but has specs that exceed G scale standards.  (NMRA is 22 volts DCC and 27 volts DC, Zimo spec is 30 volts)

      There is a free software download for the sound (Oliver zoffi), and there is a 'lode Code' at $25 for the decoder to load the different galloping goose sounds from H. Dappen.

      I used the free sound and it runs through the gears  and has a motor startup sound and 'floating' valve sound.

      I even use the P22 version on the LGB stainz locos.

      My only issue is there is only 1 input sensor on this decoder, but I find the motor speed via Bemf works great.  THe newer but not yet available MS decoder should have 2 inputs.

    • I have a Bachmann Spectrum 1:20.3 Rail truck and i want to know what decoder others are using.  i would  like one that can power it as well as provide sound.  I am using the CVP products Easy DCC 10 amp system.  Since the rail truck will not be pulling anything but its self on level track, ( No Grades on layout) can i use a HO scale decoder?

    • thank you.  Where do I put the small caps you mention?

    • 7809 center pin (ground) goes to decoder ground, input pin to decoder +  (22 volts).

      So regulator has input pin and ground pin tied to decoder.

       

      Smoke unit has one wire to a function (F6) and the other wire to regulator plus output.

      If using the LGB smoke unit, 7809 needs for you to modify cv 137, 138, 139 for different smoke loads and cv 132 (if using F6) to 72 for steam or 80 for diesel.

      Just remember the higher the number the higher the voltage to the smoke unit. I like small smoke at standing, medium for running and lots for accelerating.

    • To verify: 

      pos wire goes from the decoder's +22v pin to the Pos lug of the 7809

      Neg lug of the 7809 goes to the Pos/white wire of the smoke stack.

      Gnd/black wire of smoke goes to the decoder F6 pin. 

      And I put one cap across the 7809 pos lug to grd lug, and one cap across the neg lug to gnd lug?

    • I use the LM7809, 1.5 amp.  I do add .01uf ceramic caps for noise reduction.  No other parts needed.  Just remember the center lead (ground/neg reference) is tied to the metal tab.

      Get the PDF by googling       LM7809 pdf

      THe LM units come in many voltages and in 100ma small transistor packages as well as t0220 at 1 or 1.5 amp.

      Voltages available are 5, 6, 8 ,9, 12, 15 (number is the voltage).  All are perfect for our train projects.  And to simulate 4 batteries like the bubble car (6.8 volts ) I add a silicon diode to the center leg of the LM7806 and get 6.7 volts.

    • How do I set up the LM7809 circuit?  Can I tie both the lamps and the smoke into this same circuit or will I need two?  

       

    • August 14, 2020 8:05 AM EDT
    • The 10 volt source is tied to the internel computer and a current surge can cause a problem.  You could try using the LM7809 tied to V+ for a voltage source for the smoke heater element.  I use the engine weight for a heat sink.

    • The smoke is programmed to the above parameters that you suggested.  They work fine. I can definitely see a difference in smoke volume, especially at idle vs acceleration.  It is more difficult to tell when the engine is going full speed as the wind is blowing it.  But it looks good.  I believe the values set are 75. 100 and 130 respectively.  

      I can see that possibly the smoke is causing a too high current draw with the 10v, though my other engines have no issues.  But I cant believe that one light bulb would cause such a fuss.

    • This may not be part of the problem, however it could change your issue.

      How did you program the smoke unit?

      I tell the function key to ignore voltage dropping on smoke and then control the heater with cv 137-139.  Also if using function 6 for smoke, I set cv114 to 128 to ignore voltage dropping on F6 plus i set CV 132 to 72 for steam smoke.  Now you get 3 different heats for the smoke unit.  Do remember to start with low values for cv 137-139 as no values would give 10 volts (read max volts from the wired power source).

      CV137 is idle smoke, no fan if using a fan driven unit

      CV138 is cruising smoke

      CV139 is heavy load accelerating smoke

    • OK, I got her back together and ran it.  Figured out that the problem only exists if I have the headlight/taillight and/or the smoke generator on.  If the lights and smoke are off, it stops as it is supposed to.  I know I have the wires wired correctly as they work in the correct direction with the lamp button on and the smoke works with F6 on.   So what would cause this?  The lamps are tied to the 10v using the CVs to drop the voltage.  

      thanks,
