Actually it has the Tsunami that works in DCC and DC. So no 8 or 9 pin decoder slot, it has an IC soldered right onto the PC board. Heres a pic http://mrr.trains.com/~/media/import/images/5/a/9/mrr-pr0910-11.ashx?mw=900

I use old atlas brass track, but it is smooth and clean, I have no gradients on my layout. My couplers are not grabbing/catching the ties. When I was running it now at the higher speeds it seemed to be better, but still doesn't like to start up nicely, it kinda jolts around almost like the flywheels aren't there. Thanks for the info.

I just bought the new athearn genesis gp15-1 with sound and hoping I would get something that runs good for the $. Nope (my bachmann gp7 runs smoother) I ran a break-in period of 20+ mins in each direction no cars, and then with cars (about 16). It is hard to get going, it should slowly go from stop to go,  looks like someones popping the clutch.  At higher speeds it kind of bobbles around like it has half square and half round wheels (fast, slow, fast, slow, fast, slow, type of speed pattern), however the wheels are round and not bent. Motor spins freely but I can hear it with the Tsunami. Other than that it looks very nice and sounds good. I am using DC (Troller 1001). Help greatly wanted/needed, should I return it?

Bachmann does have allot of schematic drawings in the "parts and service/product reference" section.
Its in there about 3/4 the way down

I found this little gem, only draw back is the 3v motor, but with 3v applied it has so much torque you can not stop it. and with grease on the gears the noise level is not to bad.

I've been wanting to build a small layout that's more then a circle but the grades always get me, I can add weight for traction but then the slow speed performance goes away, this just might be the cure.

What is that?, is that a Christmas tree ornament spinner? You must have some ornaments that weigh 25-50lbs

Yes gear ratios help allot! Does anyone remember those good old roundhouse box cabs? With mine I can crank up the ole troller and she top's out at about 15-20smph, but she sounds like she's got "pure dc sound".  That old technology of strait cut gears, wish I could get some helical's for it.

This is just for fun. Think of some sort of motor that has allot of torque but is smooth and slow, that can be applied into an HO gauge. Get your Imaginative juices flowing ! Go crazy, be extravagant, think elaborate!
I know 5 pole skewed motors are good but...

Ideas: Ball Bearings, 12 pole SKEWED, ?brushless?, etc

See what you can think of

pancake motors not allowed

Q: What are those marklin "sine" drives, are they some kinda stepper motor?

Hey Bachmann, When are the new gp7's coming out?
