Frisco residents Phil and Geda Condit donated a mini custom-made steam locomotive to the Museum of the American Railroad, which recently put it on display.
A fundraising campaign will kick off soon to build mini tracks and buy three to six mini passenger cars. The plan is to run the locomotive in a loop around the nonprofit museum's rail yard to showcase its collection of full-size locomotives and passenger cars.
Think of the 16-foot-long, 5,000-pound locomotive as the baby brother to the museum's prized Union Pacific Big Boy No. 4018. That behemoth steam engine is 133 feet long and weighs 600 tons — 1.2 million pounds.
