I've decided to tackle a project that has been on my to-do list for ages: adding new weighted floors to the ConCor autoracks. Labor Day Weekend is coming up and I think this will be a good time to make some progress on this task.

When the ConCor autoracks came out, I was heavily into the modular N-trak scene, and there was nothing better than seeing a nice, long train of racks making its way along the layout. The stock models looked great and ran fine on the modular layout, once we retrofitted them with KD trucks, wheels, and couplers.

On the mighty MKT, the autoracks are "okay", but tend to be a bit light, and also have a top-heavy "wobble" that bugs me. Many years ago, I purchased 20 of the Alan Curtis autorack upgrade kits, which replaces the plastic floor of the model with a heavier metal casting. The result is a much better tracking car, with none of the "wobble". You can still buy the upgrade kits at N Scale Kits.

I have 18 castings, and that will just about meet my needs. You drill holes in the corners of the floor and, using a coping saw or jewelers saw, cut out the floor. The metal casting is then glued in place, and new trucks and couplers added.

I post some photos of the upgraded cars when I have completed them.

Happy Labor Day, everybody!
