The layout is HO in a folded dog bone pattern to allow a double tracked main line on two levels connected by the mother of all helix tracks. Strategically located crossovers allow flexibility. E.G. We have the layout configured as a single track line at present but plan to revert to two track main for the November Open Houses. It is DCC (Digitrax) with a voltage setting that allows scale speeds and is segmented into three power districts. 2005 witnessed the introduction of some radio controlled throttles. The main line crossovers are automated under stationary decoders as well as local controls located on the fascia. Operations tend toward the mix of both diesel and steam power with many locomotives equipped with realistic sound decoders. Hagerstown yard is the focus of operations with a large classification yard, local business sidings, passenger station and a complete engine and car service area with a 120' operating turntable. Conowingo has a small classification yard and several industrial sidings. Rising Sun features a line down the center of the main street and an active industrial area with an almost operating coal dump for the power plant. There is a balloon track around the industrial section to facilitate switching operations. The Strasburg branch has an interchange yard with an extension of the yard lead leading to staging tracks, a large coal mine and breaker, engine service tracks, passenger and freight depot and a wye to turn engines and the Doodlebug. The flyover behind the depot is the most severe grade on the entire railroad. Extreme degrees of curvature here result in the flyover restriction to four axle units for switching moves. There are three sidings at the top of the flyover; two that serve a mountain logging industry - both pulpwood and logs, and one siding for dumping mine-run slate and spoils from the coal breaker. The solid fill section of the flyover ends at a rustic wooden trestle. Many other layout areas are sceniced but there is always more to add. The City and Port of Wilmington is an example of a large and active urban area. The city is has a new operating downtown trolley route. Freight is interchanged across the Delaware river on a car ferry from the port. The layout is partially signaled to give engineers and operating crews an idea of what is occurring at/on out-of-sight sections.
