RPM update

As we turn the corner into the last few months of 2022, the RPM calendar has several events scheduled through October. Check the calendar for an RPM near you and make plans to attend.

The joint convention of the L&N and Southern historical groups was recently added. Several RPM presentations and a model display area are part of the Chattanooga event. The convention will be held at the Tennessee Valley Railroad Museum, which will also host a couple events.

A few 2023 events have been announced, too. For your long term planning, save the October 27 & 28 dates for the Naperville RPM! It will be held in the Northern Illinois University conference center just mile or so from previous locations of this long running Chicago event. More details will be shared coming in early 2023.

We were in the Grand Ballroom of the Forest Hill Civic Center, with clinics in room 202 and a nearby break room. The room was pretty large. They had free water and soft drinks in the kitchen, which were paid for by the $20 entrance fee.

Uncoupling levers are found on all freight cars on North American rails. In my 1926 focus, these levers would pull a pin from the top of the coupler to allow the knuckle to open. One version that was common on many early freight cars were the Carmer uncoupling levers, as seen in the DL&W box car in the lead image. These were a two-part design with many variations. Let’s review some basics and installation of these details on a few HO scale box cars.
