As a train screeches to a halt at the Huntingdon, Pennsylvania, station, William Chittester’s eyes widen as he looks up at his grandfather beside him. In an instant, the once-quiet station comes to life as arriving passengers shuffle onto the platform and those departing hurriedly take their places aboard the locomotive.
The conductor emerges, bellows out a final call and gives the engineer a wave of approval before returning to his place aboard the train. With the shriek of a whistle, the engines gradually start to roll the train ahead until it’s eventually barreling toward its next destination.
For Chittester, a senior majoring in geography at Penn State, these moments from his childhood aren’t just fond memories spent with his grandfather, they’re also a precursor to his current role as president of the Penn State Model Railroad Club at University Park.
Operating since 1955, the club meets twice a week in the basement of Pinchot Hall (a residence hall on the northeastern side of campus) to maintain a layout of tracks taking up nearly an entire 1,200-square-foot room with well over 50 locomotives and approximately 1,000 train cars.
The expansive setup features several built-to-scale scenes, including a miniaturized rock quarry, Hershey’s chocolate factory, a bus depot and even a 3-D-printed Nittany Lion Shrine. But maintaining these lifelike miniatures isn’t an easy task — it requires finesse, ingenuity and the help of technology.
Using the systems Digital Command Control (DCC) and Java Model Railroad Interface (JMRI), club members have nearly unlimited control over every aspect of each locomotive, trackwork and signal. DCC works by sending packets of information from wired and wireless handheld devices to a centralized command station that communicates through the track to each train. “With our handheld controllers, we’ll send information to the command station, which then sends it over the tracks,” Chittester said. “Each locomotive on the layout has its own microprocessor that receives the information, and based on what the command station tells it to do, the train will perform that task.”
For example, as an engine picks up speed down a long stretch of track, Chittester wirelessly conducts the locomotive with a few button presses and knob turns on the handheld controller. While the train approaches a tunnel, Chittester turns on the lights, sounds the whistle and activates the familiar chugga-chugga noise of an accelerating train.
