Mt Washington Cog, 150 year old steam engine

I've taken the ride.

If you go, pay attention to the schedule. They still run one steam loco per day, so two round trips, but most runs up and down the mountain are powered by the biodiesel fleet. The cog railroad dieselized to reduce operational & maintenance costs, and to reduce emissions. Parts for the steamers were getting hard to source, and while the coal smoke coming out of the steam locomotive makes for good photos, it’s not always the best image, if you know what I mean.
