CMX User Converts HO CMX to On3

CMX User Converts HO CMX to On3

Posted by on Jan 2, 2015 in Miscellaneous, Tony's Tips |

I’m sharing with you my version of a modification to your track cleaning car for use on ON3. We recently had the opportunity to use this car to keep our track clean at the O Scale West Convention where we set up and operated our Nitty Gritty Narrow Gaugers modular Layout.


Everything worked as intended using Isopropyl Alcohol as a cleaning medium. The original drag supplied on your as-delivered car accommodates the 0.750″ ON3 track gauge just fine. Don Fiehmann was kind enough to photograph and annotate my ON3 modification of your track cleaning car. This annotated photograph is attached as a JPG file.

Below is an Auto Cad illustration depicting the design of the replacement/new parts for the ON3 conversion. This design is based upon the use of standard ON3 trucks and #503 Kadee couplers.
