Memorial Day weekend marks the start of the Mount Washington Cog Railway's daily trips to the summit of the highest peak in the Northeast.
The Cog Railway opened its 2014 season April 26, but operated weekends only until now.
This season marks the 145th year of operation of "the Cog."
The popular tourist attraction is also rolling out a new biodiesel engine during the holiday weekend. The new engine is named Metallak, in honor of the last surviving member of the local Abenaki tribe.
Each 3-hour round trip on the Cog includes an hour spent at the summit, where passengers get free admission to the new summit weather presentation created by the Mount Washington Observatory — titled Extreme Mount Washington.
