n. 1. One of a series of teeth, as on the rim of a wheel or gear, whose engagement transmits successive motive force to a corresponding wheel or gear.
A deep-rooted history of invention and fabrication has always been one of the Mount Washington Cog Railway's most intriguing attributes. The Cog has managed to stay in private ownership and in operation consistently for over 144 years. It has adapted to and overcome adverse opinion, the Great Depression, the Hurricane of '38, and the challenge of technology to become one of New Hampshire's most successful historical attractions.
Designated as a National Historic Engineering Landmark in 1976, The Cog was referred to as "One of the greatest wonders of all time" by the Boston Transcript at its inauguration in 1868. It can certainly be argued that this is still true to this day.
The advent of biodiesel continues that tradition of innovation and improvement that has characterized the Cog Railway since 1869. From being the first mountain climbing cog railway in the world to the solar-powered track switches to the advanced Parker IQAN on-board computer package, The Cog continues to be a leader in cutting edge technology.
In Tech News, The Cog has recently been featured on Motorweek Clean Cities!
