Hi Guys. I am new to this site, but have been a serious model railroader since 12/1968 when I got my first N Scale Aurora Postage Stamp Train Set for Christmas. By the way, I was a Senior in High School at the time. I had Lionel in the basement, but went nuts over N. Over the years I collected and then when I grew up(?) and had children of my own, I wanted something BIG under the tree, more than O/O27. Turned to G and since have a nice collection. This Christmas, I got a USA Trains SD70 MAC in the newest BNSF "Swoosh" scheme. WOW, no DOUBLE WOW. Anyway, this year decided to put the G-Scale outside after not running them for at least 2 or 3 years. (I live in FL, so it works out) I have a B-Mann Connie 2-8-0 in WP&YR. My wife bought this for me after a cruise to Alaska and a ride on the above railroad. As I said, have not run any of my G for quite sometime, so when I put the Connie on the track and hit the power, all I heard was the motor whining and there was absolutely no movement. I suspect the gears as described above. Thanks to Eric for taking the bull-by-the-horns to get the instructions to dismantle the loco and fix the problem. Since I work on my N, should not be an issue to work on something this BIG. I will let you know how I make out. Roger McCoy
