Mt Washington Cog Railway


In hopes of creating more Lego Train sets, I designed a version of the Peppersass cog engine built by Sylvester Marsh in 1866. Included in the set is a design for the Peppersass and the Moosilauke steam engine. This set commemorates a significant engineering feet, and is a stylish train to include in any Lego train enthusiast's collection.
The Peppersass engine is set on a display stand, similar to how it can be viewed at the base site (grass underneath instead of cement since it is more colorful). There is a small plaque for the name of the set engine to be included.
I redesigned the Moosilauke engine to allow it to be used as a play set instead of the previous design which was more display set.

Quick History Notes about the Cog Railway:

Originally named "The Hero", the first cog engine was renamed "Peppersass" because of the boiler's design. Sylvester Marsh designed the engine to ascend Mt. Washington's summit, and it traveled close to the destination: 6,288 feet (1,917 m) above sea level. The engine uses cogs to climb up a rack rail design on the tracks, pushing one passenger car to the peak.
In 1976, the New Hampshire Cog Railway was designated as a National Historic Engineering Landmark.
The Moosilauke engine was later created (1883) to perform the trip. While not the first train with a horizontal boiler, it was used for many years until retiring to the village of Twin Mountains in 2013.

Request for Help:

Please help in supporting this project. If you like the design, please share this with your friends and family, so they can help make this set and others a reality. We need a lot of supporters. Thanks

Future Updates:

There are plans to update this set with sticker designs to feel more authenticate, so keep your eyes open for the updates. The stickers for the passenger train are currently the most difficult, as I try to balance authenticity with ease of building.
