Denver, South Park and Pacific Railroad: The Denver, South Park, and Pacific Railroad (later called the Denver, Leadville and Gunnison Railway) was a historic narrow gauge railroad that operated in Colorado in the western United States in the late 19th century.  The railroad opened up the first rail routes to a large section of the central Colorado mining district in the decades of the mineral boom.  The railroad took its name from the fact that its main line from Denver ascended the Platte Canyon and traversed South Park.  Founded in 1872 by Colorado Governor John Evans, the company was purchased by the Union Pacific Railway in 1880, though it continued to be operated independently.  The line went bankrupt in 1889 and was reorganized under the new moniker the Denver, Leadville and Gunnison Railway.  When the Union Pacific went bankrupt in 1893, the DL&G lines went into receivership and were eventually sold to the Colorado and Southern Railway.  In the first half of the 20th century, nearly all the company's original lines were dismantled or converted into .  The last train to run the old DSP&P tracks was from Como, Colorado on April 11, 1937.  A section of the standard gauge line between Leadville and Climax is still operated as a passenger excursion railroad called the Leadville, Colorado and Southern Railroad.  At its peak the Denver, South Park and Pacific Railroad had 335 mi of narrow gauge line, making it the largest narrow gauge railroad in the state of Colorado.

Standard gauge: The standard gauge (also Stephenson gauge named after George Stephenson, International gauge, or normal gauge) is a widely used railway track gauge.  Approximately 55% of the lines in the world use this gauge.  All high-speed rail lines, except those in Russia, Uzbekistan, Finland and Australia, utilize standard gauge.  The distance between the inside edges of the rails is defined to be 1435 mm except in the United States, where it is still defined in Imperial and US customary units as approximately 4 ft 8½ in.  It is also called the UIC gauge or UIC track gauge, the European gauge in the EU and Russia, or uniform gauge in Queensland, Australia. u

Rapid City, South Dakota: Rapid City (Lakota: "Mni Lúzahaŋ Otȟúŋwahe" ; "Swift Water City") is the second-largest city in South Dakota (after Sioux Falls) and the county seat of Pennington County.  Named after Rapid Creek, on which the city is established, it is set against the eastern slope of the Black Hills mountain range.  The population was 67,956 as of the 2010 Census.  Known as the "Gateway to the Black Hills" and the "City of Presidents", it is split by a low mountain ridge that divides the western and eastern parts of the city.  Ellsworth Air Force Base is located on the outskirts of the city.  Camp Rapid, a part of the South Dakota Army National Guard, is located in the western part of the city.  The historic "Old West" town of Deadwood is nearby.  In the neighboring Black Hills are the popular tourist attractions of Mount Rushmore, the Crazy Horse Memorial, Custer State Park, and Wind Cave National Park.

Silver Star (NZR train): The Silver Star was a luxury passenger train that ran overnight between Auckland and Wellington on the North Island Main Trunk railway of New Zealand.  The train ran from Monday, 6 September 1971 until Sunday, 8 June 1979.  It replaced the "Night Limited" express passenger trains, which provided a faster service than the "Ordinary" Expresses by stopping at only six intermediate stations en route and not dragging postal or parcels vans at the rear.  Designed as a "hotel on wheels", its carriages were distinctive in New Zealand; rather than being painted in the traditional red, the "Silver Star"' s carriages were made of stainless steel, and silver in appearance.  Original planning of the train envisaged the sleeping cars being the basis of new standard NZR passenger stock with future passenger trains of 6 carriages and van, 7 stainless steel units of 30 tons each (210) tons pulled by a 1425 hp DA.  However planning for the Limited replacement became more ambitious in the early 1960s, moving away from 25 ton, 55 ft stainless carriages of the type used on the 3 ft 6inch, QR Sunlander to sleeping cars of standard gauge 9 ft 9inch, standard gauge loading gauge.  As a result the usual Silver star consist of 35 ton carriages would weigh 410 tons and lead to the order for superpower DX locomotive of 2750 hp from General Electric to pull them and express freight on the NIMT and result in a large trackside work on the NIMT and the Silver stars alternative route via Marton- Wanganu-Stratford - Taurmaranui, to accommodate standard gauge width carriages running on 3 ft 6 inch.

Rail transport in Victoria: Rail transport in Victoria, Australia, is provided by a number of railway operators who operate over the government-owned railway lines.  Victorian lines use broad gauge, with the exception of a number of standard gauge freight and interstate lines, a few experimental narrow gauge lines, and various private logging, mining and industrial railways.

Nevada Short Line Railway: The Nevada Short Line Railway ("Silver Belt Railroad") was a 12.6 mi , narrow gauge railroad that ran east from Oreana (also known as Nenzel) to the silver mining area of Rochester, Nevada.  The railway terminated near, but did not connect with, the Southern Pacific Railroad (SP) in Oreana due to the Nevada Short Line being gauge and the SP being a standard gauge mainline.  The railway intended to eventually transition to standard gauge, but this never happened.

Black Hills and Fort Pierre Railroad: The Black Hills and Fort Pierre Railroad (BH&FP) was a narrow gauge railroad in the Black Hills of the U.S. state of South Dakota.

Black Hills gold jewelry: Black Hills gold jewelry is a type of jewelry manufactured in the Black Hills of South Dakota.  It was first created in the 1870s during the Black Hills Gold Rush by a French goldsmith named Henri LeBeau, who is said to have dreamed about the design after passing out from thirst and starvation.  Black Hills gold jewelry depicts leaves, grape clusters and vines, and is made with alloys of gold with standard yellow gold as well as green and pink gold.  In 1980, the 8th Circuit affirmed an injunction ruling that if a manufacturer was to call its jewelry Black Hills Gold, then it must be made in the Black Hills.  The state of South Dakota designated Black Hills gold as the official state jewelry in 1988.
