Gift to the Frisco Heritage Center

"Based on an 1880s design, it was essentially hand-built by the Mammoth Locomotive Works of Palisade, Colorado. It is designed to pull open-air passenger cars as a ride at amusement parks and other attractions...

“We can’t think of a more fitting place to display and operate the train. We are thrilled to share this gift with residents and visitors to Frisco, North Texas and the entire Country,” said Phil Condit, retired Boeing CEO and Chairman. He explained that he and wife, Geda, worked closely with Geda’s brother, former Frisco mayor, Maher Maso, in envisioning the project. The exquisitely crafted and detailed locomotive represents thousands of hours of work by a small cadre of skilled people. Almost a lost art, the engine is made up of hundreds of miniature machined parts, castings, and fabricated pieces that produce and function on steam. It can pull up to four matching one-fourth scaled cars that carry riders on a 15-inch gauge miniature railroad.

The beautiful 15" gauge, 3" scale locomotive featured in our header was donated to the Frisco Heritage Center by Phil and Geda Condit.
