You'll need to buy a big rattle can of flat black to properly weather it to show where the black smoke belches from the turbocharger, and of course a proper coat of grime (Hays Watkins notoriously declared that dirty locomotives pull the same amount of freight that clean ones do as he shut down wash racks all over the system...) then you'll have to go out and purchase a couple of Western Maryland GP9s, since even at twice the age of the Uboat, they ran more reliably and will come in handy to tow it's dead rear end around your layout.And don't forget to file a wheel or two flat so you get the proper sound effects.Lee
As noted, early in this thread, the first HO scale locomotive that I bought for the Seaboard Central 3.0 was this Athearn Genesis GP40-2:However, out of the box, it didn't run as smoothly in reverse as it did running forward. There was slight surging. It also developed a growling/squealing in the driveline, again when running in reverse. Running only forward isn't practical for a Geep , so I finally got around to contacting Athearn this week, who agreed to accept it for warranty repair. I shipped it today. Keep your fingers crossed.DFF
I suspect dry bearings...Athearn RTR/Blue Box and Genesis four axle (but not Genesis six axle units) all use the same drivetrain components. The worms sit under clips on top of the trucks and tend to growl/squeal when they torque to one end or the other.I've actually seen them fixed with small washers holding the worm centered.A bit too late to try it, but then I almost never have anything under warranty so I don't usually consider that an option
A lack of lubrication is what I thought, too. But, I was curious as to why the noise was only in one direction. You may have answered that one. If if comes back and is not corrected (or occurs again), I'll know what to try to fix it.If it was an Atlas N scale locomotive, I would have just torn it down and lubed it. But, these HO scale locomotives look a lot more complicated under the hood. So, instead of voiding the warranty, I chose to take advantage of it.Thanks,DFF
Send me an email whenever -- [username]@gmail.com. More than happy to discuss anything and everything regarding technical info on HO or N locos. I have at least 2 or 3 apart pretty much all the time.
FYI, the Athearn units will eventually burn out the 1.5 bulbs they use in the headlights/beacons/Gyralights. Let me know when that happens and I'll walk you through swapping some LEDs in there.
