Chris,

I am not familiar with the controller you are referring to, however it can be determined with a simple volt meter. Read the voltage across the output on the controller. If it ramps up with the increase in the controller knob, then it is not a PWM. If the meter immediately goes to full voltage (probably somewhere in the neighborhood of 19V) then it is a PWM.

Gary,

All scales measure track to the centerline of the track. The difference between smaller scales and large scale is large scale refers to circle diameter instead of radius. Can sometimes be confusing.

Gary,

I can't tell you the dimensions of the oval as I have never owned a complete set. I CAN tell you that the curves are 2 foot radius on the centerline of the track. So add the length of the ties and that will give you outside dimensions. As for the straights, I am almost positive they are 1 foot each. Again the math should be fairly easy.

Happy Railroading.

Morris,

I believe all the Big Hauler ten wheelers are furnished with motors in the 19-24 volt range. That said, Bachmann has a habit of gearing their locos a bit to fast for most folk's taste. As Kevin has stated, most narrow gauge (and the ten wheeler was patterned after the East Tennessee and Western North Carolina narrow gauge) never ran much over 25 - 30.  I believe the Huckleberry Railroad in Michigan, owner of the D&RGW K27 #464, has a placard on the backhead that reads 'Do not exceed 30 miles per hour.

That said, I agree with Kevin that a 14.8v Lithium battery pack would be a perfect fit for the Big Hauler locomotives. Limiting the top speed of the engine to something in the less than light speed of factory gearing.

Morris,

Although a bit dated, George Schreyer has a very good web site with tons of Bachmann, and in particular Big Hauler information. Here is a link to his Big Hauler pages. http://www.girr.org/girr/tips/tips1/big_hauler_tips.html#rc

Although not particularly 'in your backyard', I would highly recommend RLD Hobbies. He has done fine work  by me on a Bachmann K27.

Dan,
I have used an LM317 or LM350 with great success in limiting voltage. I have an LM350 limiting the voltage to my Airwire controlled K27 to 16.5 volts and an LM315 dropping to 5 volts for the circulation fan for the electronics in the tender.

Both are from this web site http://www.learningaboutelectronics.com/Articles/LM317-resistor-and-voltage-calculator.php.

Happy Rails.....

Tony,

There is a horizontal seam on the back of the headlamp assembly. CAREFULLY separate the top and bottom half of the light assembly with a thin straight edge. I used an old Exacto chisel blade (I forget the number).

For additional protection for your LED headlight, add an additional 1N4001 diode in the circuit, attaching the Anode of the 1N4001 to the Cathode of the LED, and the Cathode of the 1N4001 to the Anode of the LED. The purpose of  this is to proved a simpler path for the reversed polarity to travel when the loco is backing up. Keep the resistor in the common  wire, positive or negative, either will work.

Steve,

Let me poke around in my junk box (the one I just acquired), I probably have a pilot for a ten wheeler you can have for the cost of shipping. It WILL most likely need a paint job as I don't believe I have any Bumble Bee junkers.

Turn the tender up side down, and remove the four screws located on the outer edges near the bolsters, fore and aft. They are in deep pockets, so they are not evident at a quick glance. Be careful when removing and re-installing them not to strip the posts on the shell.
11  Discussion Boards / Large / Re: pulling Power on: June 11, 2018, 08:07:25 PM
Not really. Depends on the cars you are pulling. My previous post is based on AMS and Bachmann Spectrum cars weighing in at the 3-4 pound per car level. My K27 is modified to add additional weight and additional gear reduction from Bachmann stock. When I first purchased the loco stock out of the box, I was able to pull in the neighborhood of 35 (can't remember the exact number) of mixed LGB/Big Hauler/USAT/Aristo cars. Models will almost always out perform their prototypical counter parts.

I have started a thread on the Narrow Gauge Discussion Forum requesting Tonnage charts for the K series of locos. You can follow along here:
http://ngdiscussion.net/phorum/read.php?1,350928
as I am also interested in the proto info.
12  Discussion Boards / Large / Re: pulling Power on: June 09, 2018, 11:57:24 PM
Are we discussing prototype or model? Generally speaking the model will pull far more than the prototype will. I have both a C-19 and a K27. The K27 is AirWire R/C, battery, with an additional gear reduction and additional weight in the smokebox. On flat level track I can pull 11 AMS/Bachman Spectrum cars, or 17 Bachman Big Hauler cars. Both are above what a prototype K27 can handle.

The C-19 will handle the same on flat level track. These numbers exceed the prototype worse than the K27 as the C-19 is a smaller loco.

Not sure on the C-19, but you can search the Narrow Gauge Discussion Forum and find prototype info on the K27.

Hope this helps.

Please don't interpret this as being curt or rude, but I suggest reading this thread completely.

http://www.bachmanntrains.com/home-usa/board/index.php/topic,27794.msg208481.html#msg208481

I am currently at the National Garden Railway Convention, and conversations with the Bachman folks pretty much echo the content of that thread. I own a K and would love to get another, but have no intentions of paying near the new price I paid for a second hand unit that I have no idea of the real condition.

Best wishes,

Bob
14  Discussion Boards / Large / Re: Will Bachmann Big Haulers or Spectrum run on Peco code 200 track on: May 28, 2018, 12:11:57 AM
Hunt,

My comments are relative to mathematics. If the 'pizza cutter' flanges on the Bachmann LS wheel sets have issues on a code 250 rail that is .250 inches high, then I would assume that the same wheel stets would have difficulties on a smaller code 200 rail that is .050 (near 1/16") smaller. Now if Peco is 'calling' it's track code 200 and in reality it is something different, that is a different discussion. Another item that will make a difference as well is the size of the 'spikes' that are molded into the tie strip of the track. Some manufacturers are thicker (taller) than others.

As for running Bachmann LS wheel sets on code 332, no I don't have any issues at all. In fact the Bachmann 31mm wheel sets are my default when replacing plastic wheel sets on all but Lionel rolling stock. Lionel I replace the truck with a USA Trains truck frame and Bachmann wheel sets.

Material of rail does not make any difference relative to the code of the rial. Code 250 is code 250 ....  .250 inches tall. The cross section will likely differ slightly dependent on the manufacturer, or why rail joiners will not necessarily play well with all track.

As for do I know folks personally? No, I do not. However over my 10 or so years in LS and reading every forum that is dedicated to LS, there have been numerous threads discussing the smaller code rail with the over size flanges on most manufacturers factory rolling stock, especially Bachmann. I can personally speak to some code 215 brass rail that I acquired probably 40 years ago that averages between .210 and .220 high, and even with hand laid spikes Bachmann wheel sets will bump on some spikes depending on the thickness of the spike head. The rail had been purchased for an 0 gauge mainline layout that never developed and the rail has been collecting dust since. I am considering doing a mining branch that will use the rail with 0 gauge wheel sets on mining cars. A big heavy but the rail is free.

I am not interested in a debate, only offering a caveat to test before committing to a large dollar purchase of track. If it works for you then that is a wonderful thing. However I tire of folks jumping with out testing and then complaining that things don't work.

Hunt, I gotta ask the question.....is that from personal experience? I know folks that have experienced issues running on code 215 aluminum. I am not sure that a blanket statement that because it says Gauge 1 on the track all products will perform on that track.

My recommendation is to confer with Peco.
