About Mount Washington Cog Railway
Mount Washington Cog Railway climbs approximately three miles from Marshfield Base Station on the western side of Mount Washington to the 6,288-foot summit during the state park’s warm-season window. The narrated trip uses a center rack and custom locomotives on grades averaging 25 percent and nearing 38 percent. Regular biodiesel summit round trips take just under three hours, including roughly an hour at the top; specifically advertised steam trips climb more slowly. From late October through early May, the year-round railway normally changes to a shorter Waumbek Station trip below treeline. Exact destination, motive power, times, and summit access belong to the selected live ticket because severe mountain weather can shorten a trip.

The Trains
The railway’s primary fleet consists of seven custom biodiesel locomotives built onsite beginning with M1 in 2008 and continuing through M7 in 2019. The operator also maintains coal-fired steam locomotives MW2 Ammonoosuc, built in 1875, and MW9 Waumbek, built in 1908. The current home page advertises 2026 steam excursions at 9 a.m. and 2:45 p.m. on Thursdays through Sundays beginning July 10, superseding the separate 2025 delay notice. Steam remains a ticket-specific product, never an assumption. Enclosed coaches are also built for the steep grade; assigned locomotive and coach can change without notice.
History
New Hampshire granted Sylvester Marsh a charter to build the mountain railway.
The first locomotive, Hero—later known as Old Peppersass—arrived and demonstrated the rack system.
Passenger service reached Jacob’s Ladder before construction continued toward the summit.
The railway opened through to the summit on July 3 as the world’s first mountain-climbing cog railway.
M1 became the railway’s first operational biodiesel passenger locomotive.
M7 completed the seven-locomotive biodiesel fleet.
A modern onsite maintenance facility and heavier rail supported the expanded year-round operation.
See full history
After a dangerous 1857 Mount Washington hike, Sylvester Marsh pursued a mechanical route to the summit and received a New Hampshire charter in 1858. His first locomotive, Hero—later nicknamed Old Peppersass—arrived in 1866. Passenger service reached Jacob’s Ladder in 1868, and the completed railway opened to the summit on July 3, 1869 as the world’s first mountain-climbing cog railway. The line moved through railroad, institutional, and family ownership across the next century while continuing to operate. Biodiesel power entered service in 2008, and major track and shop investment in 2020–2021 supported the present year-round program.
Frequently Asked Questions
How long is the Mount Washington Cog Railway trip?
The regular biodiesel summit round trip is just under three hours: roughly 45 minutes up, about an hour at the summit, and the return. Steam climbs more slowly. The winter Waumbek round trip is about one hour.
Does the train run year-round?
Yes, but not always to the summit. The published 2026 summit window is May 2–October 25; from October 26 into early May 2027, the normal destination is Waumbek Station below treeline.
Is every train steam-powered?
No. Biodiesel locomotives provide the primary service. Steam is offered only on specifically advertised departures, currently listed at 9 a.m. and 2:45 p.m. Thursdays through Sundays beginning July 10, 2026.
How early should I arrive?
Arrive at least 45 minutes before departure. Boarding begins 15 minutes before the scheduled time, and trains cannot wait for late passengers.
Can a wheelchair go on the train?
The buildings are accessible, but the coaches have three steps, narrow aisles, and narrow doorways. Riders must transfer to a coach seat. Folding wheelchairs or walkers may be carried if space allows; motorized wheelchairs cannot be transported.
Are there restrooms onboard?
No. Use the facilities at Marshfield before boarding. Restrooms are also available at Waumbek and at the summit when the state visitor building is open.
Who operates the summit visitor center?
New Hampshire State Parks, not the railway. Its operating dates and services can differ from the Cog schedule.
Can I add a Mount Washington Observatory tour?
Yes when inventory and summit access allow, but reserve it separately. The Observatory instructs Cog passengers to select a train departing one hour before the tour.
Are the two remaining sunrise dates complete?
Yes for the official 2026 sunrise program checked August 13. The operator published three trips; July 24 has passed, leaving August 14 and September 12.
