Here's another look at Baldwin 60000, an unsung hero of steam loco development.
To my knowledge no one has made an accurate O scale model of this unique loco. It would be a natural for MTH because reportedly the prototype was delivered in PURPLE paint! As a demonstrator it ran on many RRs and was fueled by both oil and coal during its demo run. And the best part... it still exists in nearly perfect condition, buried in the basement of Philadelphia's Franklin Institute for over 70 years!
