The Broadmoor Pikes Peak Cog Railway, Colorado, United States

The Broadmoor Pikes Peak Cog Railway (also known as the Pikes Peak Cog Railway) is an Abt rack systemcog railway with 4 ft 8 1⁄2 in (1,435 mm) standard gauge track in Colorado, United States, climbing the well-known mountain Pikes Peak. The base station is in Manitou Springs, Colorado, near Colorado Springs. The railway is the highest in North America by a considerable margin. It was built and operated for the tourist trade following its use by people who lived above the town below. As of February 2019, the railway will remain closed until 2021, when it will be reopened with new equipment.

The Abt rack system will be replaced with the Strub rack system. The railway was started by Zalmon G. Simmons, inventor and founder of the Simmons Beautyrest Mattress Company. The company was founded in 1889 and limited service to the Halfway House Hotel was started in 1890. On June 30, 1891, the first train reached the summit.

 

A number of steam locomotives were built for the line by the Baldwin Locomotive Works, all rack-only locomotives with steeply inclined boilers to keep them level on the average 16% grades. Operating steam locomotives on such a line was back-breaking work and expensive, so when more modern forms of traction became available, the railway was eager to modernize.

A gasoline-powered railcar #7 was constructed in 1938. It was designed to be a cheaper alternative to the steam locomotives enabling economic service during quieter times of the year. Proving a huge success, the railway soon bought more internal combustion engined trains. This car is still on property having been re-engined with a more modern Cummins diesel.

The next were five 'streamlined' diesel locomotives from General Electric, which were equipped with matching passenger cars, acquired from 1939 onward. These slowly supplanted the steam locomotives, though some steam operations persisted until the 1960s as backup power and to operate the snow-clearing train (where their greater weight meant they were less likely to derail). A number of the steam locomotives are now on static display, in Manitou and elsewhere, and the Railway still has an operational steam locomotive (#4) and an original coach. The steam locomotive was put out of service for many years before being retrieved from a museum and brought back to service in 1980.

In 1964 the railway needed more equipment, but General Electric was not interested in the business.The railway went abroad, to Switzerland, home of most of the world's cog railways. In 1964, the Swiss Locomotive and Machine Works in Winterthur provided two bright red railcars, very similar to equipment used on many Swiss railways. Unit 14 was delivered in 1964 with a pair of air-cooled, 8-cylinder diesel engines that proved to be less than satisfactory on the railroad above treeline. Unit 14 was returned to Switzerland and redesigned to have facilities for water cooling. Unit 14's twin, Unit 15, was also rebuilt to house a pair of water-cooled Cummins 724's. Two more (Units 16 and 17) were built in 1968 to increase the railroads capacity. All four of these units eventually received new Cummins 855 diesels. As of 2017 all four original Swiss trains are still in operation at the Manitou and Pikes Peak Cog Railway.

As tourism increased in the 1970s the railway needed more capacity. In 1976 M&PPRy took delivery of two larger two-car articulated railcars from the Swiss Locomotive and Machine Works of Winterthur, designated Train 18 and Train 19. Passing sidings were built in several places at about the same time, allowing trains to pass at various points on the mountainside. Trains could previously pass only at the Mountain View siding, permitting only three trains a day up the mountain. Eight trains per day became possible with the new equipment and sidings (two additional larger railcars were delivered from SLM; Unit 24 in 1984 and the last, Unit 25, in 1989).

Rolling stock on the M&PPRy consists of four 214-passenger articulated Swiss-built railcars, four 78-passenger Swiss-built railcars, four GE built locomotives (one being rebuilt in 2017 to modern specifications), one snowplow (#22 - built upon the frame of a GE locomotive), one 23-passenger diesel railcar (#7), one steam locomotive (#4 - built by Baldwin), a Winter-Weiss "streamliner" coach, and an original Wasson wooden coach (#104). Only the Swiss-built railcars carry regular passengers. The steam locomotive and passenger coaches are used on rare special occasions, but can no longer make it to the summit due to the demolition of most water towers on the line.

As of 2017 the railway owns enough equipment (railcars and snow plows) to run six to eight trains per day from mid-May through mid-September. During "off-peak" months (mid-September through mid-December and mid-March through mid-May), from one to five trains are run per day, with additional trains added if there is sufficient demand.The railway was usually closed from mid-December through mid-March unless the snow plows were able to clear the line, but in 2006 the railway began year-round service. The winter service varies according to demand: in January, for example, trains run once a day on weekends and holidays. These Winter operations were suspended on October 29, 2017, for maintenance to the railway. In March 2018 it was announced that the railway would remain closed indefinitely while feasibility studies are completed.

On June 13, 2018, the Manitou Springs City Council approved a pair of tax incentives to fund repairs of the railway. On November 29, 2018, it was announced that the tax incentives had been approved, and that reconstruction would begin in Spring 2019 for a projected 2021 reopening; the project will see all track replaced, the Manitou Springs depot remodeled, and Cars 14, 16, and 17 retired (Car 15 will be retained for maintenance-of-way duties) in favor of three trainsets manufactured by Stadler Rail; the Stadler order consists of three locomotives and nine passenger cars, marking a return to locomotive-hauled trains; Cars 18-19 and 24-25 will be refurbished and remain in service.

On November 19, 2020, it was reported that the new Stadler rolling stock is ready for commissioning.
