If you' ve been a modeler/railfan for a decade or two, your mental image of the typical coal gon is probably Thrall's 4,000-cubic-foot "High Side" gon as offered by MDC. Similar gons were built by Pullman, Ortner, Darby, Evans and others. Heavy side posts and a /lat /loor make for a simple, rugged, easy to-build and easy-to-maintain gon. But that style of gon hasn't been popular in nearly 15 years, and while most are still in service, some are now fi nding their way into scrap metal service (remember, PAGE 4 RAILMODEL JOURNAL - DECEMBER 1995 lime jockeying the cars back and forth, because it isn't easy to spot a 132-ton gondola on a dime using a diesel loco motive with air brakes. Some utilities use an automatic car spotter that grabs hold of the couplers of a couple of cars at a ti me and drags the whole train through the dumper; it's still not fast, and you still have to maintain a big dumper. So why bother? It's a matter of economics. Rapid discharge hoppers cost more to buy, cost more to maintain with their complicated pneumatically controlled gates, and cost more to run because you're hauling around that extra hardware rather than the equivalent weight in coal.
