Marx fans often complain Marx didn’t make quite enough variety in its 3/16 scale line. Fortunately, it’s pretty easy to get a bit more variety out of it by making a 3/16 scale Marx ore car. And you can do it all with original Marx parts.
I did not invent this technique. Last week Al Osterud, a veteran Marx collector of many decades, shared a technique for removing and installing Marx coupler springs without the skills and steady hand of a microsurgeon.
All you need is a piece of 1/8-inch K&S square tube, which resembles the tool Marx used to install them at the factory, and a toothpick or a straightened paper clip. Marx wouldn’t make anything that wasn’t easy to put together, which made its couplers so maddening to work on. Why was it easy in the factory and nearly impossible at home? With the right tools, it is indeed easy.
I had a Marx 999 that didn’t run well when I pulled it out of storage. When pushing it along the track a few times didn’t yield any measurable improvement, I decided I’d better take it apart and give it a thorough cleaning.
In this case, I worked on a Marx 999, but everything I did applies to any other O gauge train Marx made except for the very late 490 locomotives, whose motors don’t seem to have been designed to let you do any more than replace the brushes.
