In 1959 Magic Mountain opened in Colorado. It was a theme park styled after the stunningly successful new Disneyland. In keeping with Disneyland's design they constructed a narrow gauge train ride. To get narrow gauge rolling stock the park reached out to Bob Richardson who was in the process of moving equipment from the original Narrow Gauge Museum in Alamosa to the new Colorado Railroad Museum in Golden.
In a heartbreaking but financially prudent move to raise money for the fledgling museum’s new building, the museum sold two of its C&S cars, refrigerator 1116 and boxcar 8308, to Magic Mountain along with Rio Grande Southern engine 42, D&RGW high side gondola 1187, and RGS caboose 0409 for use on the tourist-hauling park train.
