I figured that had to be the case since it came with a DC train set.  We actually have 3 of the speed controllers but only one of the odd cables that connect them to the track. They have a 3.5mm plug on one end and some sort of track clip on the other.  Does Bachmann sell a replacement cable?  If not is there another place to at least buy a cable with the 3.5mm plug.  Not even sure what type of plug it is.  (stereo?,Mono?, other?)

Thanks Loco Bill.  The locomotive is an Aristocraft FA with 2 motors.  We had a MRC Trainpower 6200 but it just started to act up so I need to find something to use for a train show this weekend.  I will bring the Bachmann 1 amp along as a backup.
I was just looking at the power pack that comes with it (AC1601000).  It lists the output as 16v AC.  I was expecting DC.  So is there a rectifier in the speed controller that converts the voltage to DC ?

We have a 16 volt, 1 amp transformer and speed controller that came with a Bachmann Big Hauler set.  Would this be capable of running an Aristocraft Engine with a pair of Aristocraft passenger cars for 6 hours?

RRConcepts sells 3 models that will do reversing operations.  The Station Master, The Station Master Reverser, and the YardMaster.   I am using the Station Master Reverser and it really works great.  It has two distinct modes of operation.  Sensor mode uses sensors and train magnets to gradually slow the train down and stop.  Reversing mode uses timing to slow the train down and diode bridged gaps in the rail for the stopping points. You can set the acceleration and deceleration rates and dwell time. You can do a LOT more tricks with the other models but the StationMaster Reverser is the best choice if you only plan on a back and forth operation. They just added a new feature that in addition to the gradual startup and slow down the train can creep in and out of the station.   Here is a link to the web page.  Note:  Study the instructions very carefully.

 It's a cylinder that contains the piston and spring.  The cylinder has "extensions"  on either side that have the holes for mounting.
I had contacted the parts department and just received a reply that they do not carry that part.  Have to buy the entire motor block.  -ouch!

Not sure how to post a photo.  Trying to attach this pdf again and it says the upload folder is full.

 Thanks again for trying to help me with this.  I am not sure if I am describing the assembly correctly.  It consists of the piston and a spring that I cannot see that is contained in an odd shaped plastic housing.  The housing has a sheet metal gasket that screws onto the back.  That is where the wire is soldered to.  The housing is held to the inside of the mudguard with two tiny screws.  It looks like the entire housing was meant to be replaced.  I have never seen that style on any other car.  But of course I am new to all of this.
  And yes the other piston assembly on the same side also failed.  -

Thanks Loco Bill for the tips
 I have the piston assembly off but I am not sure how to get the piston and spring out of it.  Do I just yank it out with brute force?  Seems there is a hard stop keeping it in.  And if I wanted to replace the piston and spring are they the same size as the ones that Bachmann uses in the truck frame of some of their other rolling stock?

 Thanks for the reply.  The spring is kind of weak but it still contacts the wheel.  I electrically tested the piston assembly by clamping a lead to the exposed piston. No current is reaching to the wire in back of the assembly.    Can you recommend a conductive lube that is really conductive?  That seems to be my only option right now.

We have this old Bachmann G scale United Traction trolley that suddenly quit working.   Traced the issue to a pair of electrical pickups both on the same side.  These are a kind of spring loaded piston assembly that contacts the inside of the wheels.  They are mounted in the mudguard frame.
Questions:  What would cause these to quit conducting electric current?  And is there any place to buy replacements?

11  Discussion Boards / Large / United Traction Trolley Lights on: February 20, 2019, 09:35:43 PM
We were given a Bachmann United Traction Trolley. It runs very well but the light do not work.  I took apart the motor block and clipped power directly into the wires and still no lights. I am assuming that they are burned out.  (both the headlights and the ceiling lights).
 Are there replacement bulbs available for the trolley.  If so is there a way to replace them without destroying the trolley?  Nothing wants to come apart.

 I also used the Labelle 106 grease that you recommended on an old Aristocraft locomotive that was having a lot of problems.  It runs like new now.  -That's great stuff.  Thanks again for the tip about that.

Have you taken the motor block apart (4 screws on top and two on the bottom)  to see where the wires go?
Also,  I was looking at the photos of the Bachmann motor block and see that they are not using the same kind of connector.   How did you resolve that issue?

I ran them both on a back and forth track for about an hour each.  The V3 Locomotive would continually chuff about every third or forth stop but the V5 locomotive did not do it at all.  The volume control was a nice addition to the V5.

15  Discussion Boards / Large / Continuous Chuff on the Big Hauler V3 on: February 13, 2019, 12:31:11 PM
We had two Big Hauler locomotives donated.  One has a V3 and the other a V5 chassis.  The V3 has a continuous chuff randomly when it stops. The V5 Big Hauler does not have that feature.  That leads me to a few questions.
Was that an intentional feature that simulates the sound of steam being released ?   Or was it an error that Bachmann corrected in the later versions? And how did they change it?   Seemed like a nice feature to me.
