The Sipping & Switching Society is a modular-railroading group associated with HO-scale railroading and our next guest has a lot of knowledge about the society and we decided he was the one to talk with. The Society is originally based in North Carolina but there also versions in the Ohio Valley and Cincinnati areas.

With a well-defined "module standard," distinguishing it from other modular approaches the are modules typically 30″ wide and often built in 2-foot length increments but this can vary. Construction uses a "waffle-style" framework to make modules lightweight but stiff enough for transport and repeated assembly. 

There's alignment pins/holes to ensure that the track ends match up exactly, typical track arrangement is two mainline tracks close to the "public" side plus an inside track for switching/yard operations. The result: very fast setup and teardown compared to less standardized modular systems. It's a very informative podcast and one we're sure you'll enjoy!!
