They are KATO locomotives.Nuff said?
Thanks for the input, Max. I'm a little confused by the Atlas string... you ended up with a loco with GP50 trucks and an original F3 motor? The GP50 trucks I can order but considering finding a suitable F3 donor is slim, any after market products that could work? Or I do have three Atlas B40-8s and 2 SD35 with no purpose in life right now.... I have a handful of GP30 as well. And would newer Kato F motors work, or are they not as worthy?
If you are going to spend money on all those parts, it'd be easier to buy an current Atlas RS3 or RS1 chassis. Both fit with no modification needed. I've been able to make these older Kato made chassis run smooth as silk. The trick is ensuring conductivity from the rails to the motor. Sounds obvious, but without flywheels you can get the jerky performance. You'll need to disassemble the entire chassis, but it is worth it. Burnish the surfaces where the motor contacts touch the frame. Burnish the areas on the bottom of the frames where the trucks make contact. I use and anti-oxidizing oil here. The trucks are where the most impact is made. Take them apart and ditch the little metal wipers. They aren't needed and I find the locos run smoother without them. If you look a the the two metal pieces that hold the axles, you'll see the "U" shaped notches where the axles fit. Close inspection will reveal flashing right where the axles sit. Can't see it, run a small round file across them. The flash will jump right out at you. I file all the flash smooth. Clean the axles well and put some of the anti-oxidizing fluid on them. Burnish the areas where the metal parts of the trucks touch the frame. I agree with others to swap out the traction tire wheels. Put the trucks back together and the chassis. I oil the worm gears and truck gears lightly. Clean the wheels and take her for a spin.The big thing about these chassis is that they need to be run regularly. I have had great success with these methods.CG
