I am currently getting more involved into the O-scale world and might have some newcomer questions. I am starting to build up a little roster of brass locomotives and just found out that the Sunset models all have a belt drive. These are not too expensive and after all I read about it one would better replace the mechanism with NWSL parts for better running qualities.
Do you guys use the original belt drive when running these or is the replacement of the mechanism common practice? I also wonder where to get a spare belt in case of breakage. My first project is a Samhongsa USRA 2-10-2 with the saied mechanism that I am going to convert into a more or less convincing C&S 900 class. I just hope that NWSL will stay in business for a long time :-)
