What's up with n scale atlas code 55.....HELP!

[Anonymous]

I recentley finished the trackwork on my coal river subdivision in n scale. I used the new code 55 atlas. Well I tried to run some test trains to see what needed tweeking. My kato locos glided along smooth as silk ( as usual), but when I ran a train being led by a couple of new atlas sd-50s bam, they get hung in the frogs of the turnouts. I don't understand it, the flanges on the atlas locos are the same as on the katos, so what's up with these things. Does anyone have the same problem , and how do you fix it. 50% of my locos are atlas, with Chessie and Seaboard road names, they were hard to come by, I don't want to sell them. HELP![:(!]

Get out your NMRA gauge and make sure those locomotives wheels are in gauge.

I checked the gauge of the wheels , they are where they're supposed to be.
It looks like the flanges on the atlas locos are wider than the ones on the katos, the ones on the atlas taper alot more than the kato.
I don't understand why atlas would make them where they don't even work on their own track. [:(!]

Older locos and rolling stock used to have deeper flanges,whether Atlas,Kato or else.However,Atlas code 55 is a rather new product and I'd be surprised that the newer Atlas locos would have problems with it..

I had no idea I could adjust the gauge on these n scale locos. Well that fixed that problem. [:)]
