The Broadmoor Manitou and Pikes Peak Cog Railway, Tourist train in Manitou Springs, Colorado, US

The Broadmoor Manitou and Pikes Peak Cog Railway is a standard-gauge rack railway from Manitou Springs (1,930 m) to the 4,302 m summit of Pikes Peak, climbing 14.3 km with an average grade of 12% and a maximum of 25%. It uses an Abt rack system, now Strub TN70, with wooden ties. Trains push wooden passenger cars uphill to prevent runaways.

Zalmon G. Simmons, founder of the Simmons Bedding Company, conceived the line in 1888 after a two-day mule trip to the summit. Construction began in 1889, built by Italian laborers with pickaxes and donkeys, and the first train reached the top on June 30, 1891. The older Mount Washington Cog Railway in New Hampshire predates it.

The railway was planned from the outset as a tourist attraction, and its trains push their cars uphill rather than pull them, so a car cannot run away on the 25% grades. Steam locomotives 1, 2, 4 and 5 survive as monuments; numbers 3 and 6 were scrapped.

The round trip takes approximately three and a half hours with trains departing daily from the restored Manitou Springs depot. It is wise to bring weather-appropriate clothing and layers since temperatures drop noticeably at higher elevations.

Passengers can observe ancient Bristlecone pine trees during the climb, some over 2,000 years old. These ancient trees grow in the higher zones and demonstrate the resilience of life in extreme conditions.
