The Cog is a really fun way to see Mt Washington and to experience living history. The conductors are all extremely knowledgeable about the history and the equipment and you will come away from the experience much more knowledgeable about both. As of my last visit, a coal-fired steam engine ran the first run of the day, all other runs were operated by diesel powered engines. If you are a true train buff you may want to secure a ride on the steam engine, but either way it will be an exciting and enjoyable experience.
You may hesitate a bit at the cost to ride, but there is a lot of cost associated with operating this line so it all goes to a good cause. Keep in mind hiking the beautiful mountain as well if you have the time and energy as there are many spectacular trails to explore.
The alpine zone at the summit is very special for the area, so please respect the trails so the fragile plants don't get damaged.
