Atlas O 2-rail GP9 wheels

vonhammer87OGR Forum Member

I got a an atlas O gold series 2-rail GP9, and was wondering if anyone had ideas on what the composition of the wheels are. From what I've heard they're plated brass.

I've had the locomotive about 2 1/2 years now, and i only run it at the club I belong into (Detroit Model Railroad Club in Holly, MI) and we hand lay all of our track (5,000+ft) using steel rail. In my opinion, i think this caused the plating wear off, and what little there is tends to pick up dirt and cause problems.

I am thinking of replacing the wheels with all-steel ones,just not sure where to find them.

thanks

Alex;

NorthWest Shortline www.NWSL.com lists upgraded geared steel wheelsets for the Atlas GP 9. Should be your best bet.

Alex,

NWSL shows this in their catalogue;

ATLAS GP9, GP38 upgrade geared wheelsets, (4) $44.95

2667-6 O 40"/172 wheels, Flush 1/8" x 1.455" axle

2668-6 O 40"/145 wheels, Flush 1/8" x 1.425" axle

2669-6 O 40"/115 wheels, Flush 1/8" x 1.405" axle

2670-6 P:48 40"/115 wheels, Flush 1/8" x 1.335" axle

2267-6 Side Gear (1) - 40DP x 22T SGd x .125" face x 1/8" bore, ($9.95)

These are listed separately from the old style Atlas/Roco wheels, but I would call NWSL to make sure.

NWSL wheels are steel, but the tread is not finished well and will lead to electrical pick up issues. Check out this link for some ideas on dealing with this. <http://www.aorailroad.com/phpBB3/viewtopic.php?f=3&t=141&start=30>
