Narrow-gauge railways in Denmark. Denmark made extensive use of narrow-gauge railways using a wide variety of gauges.

Industrial railways

Denmark had many industrial and agricultural narrow-gauge railways.

Tracks that display equipment from roe- and industrial tracks (brickworks, peatworks), and where conversion has often taken place for passenger transport.

About  of  gauge lines were constructed by ten companies, three on the island of Bornholm, Bornholm railways and Bornholms railway museum (Bornholms Jernbanemuseum), the rest in the peninsula of Jutland. Among these railway lines were the Skagen Line (converted to standard gauge in 1924), Amtsbanerne på Als, Apenrader Kreisbahn, Haderslebener Kreisbahn, Horsens-Tørring, Horsens-Bryrup and Kolding-Egtved and also Århus Tramways (Århus Sporveje) and Skjoldenæsholm Tram Museum, Ringsted  and .
 Voldbanen  this track gauge was used here and  and standard gauge  was also been used here on this military railway.

Great Belt Tunnel, used to transport the tunnel tubes during the construction of the Great Belt Tunnel. This narrow gauge was also used for major construction works, 900 mm.
 Cement factory Denmark, built in 1905. The cement factory was located at the current Eternit factory. Trace gauge 900 mm.

Iceland, Kingdom of Denmark, The Danish Commonwealth 1380-1944

The railway was operated by two steam locomotives built by the Arnold Jung Lokomotivfabrik of Germanycs.
Reykjavík Harbour Railway .
 Oil drums from the new quay at Örfisey (where Reykjavík's oil terminal still stands today) into the city centre;
 Meat for export from the Sláturfélag Suðurlands meat processing plant at Skúlagata to the harbour;
 Timber and aggregate for building construction in the city centre; and
 Coal from the harbour to local distributors.
The railway was again used for other purposes in 1926 during the construction of Landspítali when cement and aggregate was transported from the harbour and one of the quarries.
Mainline railways in the 1900s, First proposals:
The first official proposals for railways in Iceland were made in 1906. The route would have run from Reykjavík to Selfoss via Þingvallavatn. That route would allow extensions to Akranes/Borgarfjörður, Rangarvöllur. Surveys were made in the summer at the instigation of the Prime Minister, Hannes Hafstein. Over the next few years,  engineer Jón Þorláksson conducted more surveys in regard to snowfall, and developed cost estimates, including a comparison between the cost of oil- and coal-powered systems.
Proposals in the 1920s:
In 1921, Alþingi decided to look at the possibility of railways again. Subsequently, in 1922–1923, a Danish engineer made surveys of a route from Reykjavík to Selfoss via Þrengsli. It was the shortest and cheapest solution. The route was envisioned to carry both passengers and freight, which would have been cheaper than existing methods of transportation. In 1927, the city development plan of Reykjavík included a railway terminus with multiple platforms, just outside the Reykjavík city centre in Norðurmýri. Automobile traffic was rising and there was a need for better roads. Comparisons were made between a road and rail system in Iceland, and it was eventually determined that roads would take priority. In 1931, plans for railways in Iceland were abandoned.

Water Works Agency, This gauge was used by industrial railways around Denmark, as well as by the Water Works Agency along the west coast of Jutland.
 Nørresundby Portland cement factory, In 1906, ØK started Nørresundby Portland cement factory in No. Uttrup north of Stigsborgvej and tipper tracks were made from the factory and the 1.5 km down to the harbour. Fuel gypsum etc. one way and cement the other way to the port and shipping. Also track from factory to grave west of Hjørringvej. The factory closed in 1932 – the tenants were about to be emptied, and on the factory site the Bates paper sack factory was established in the old buildings. The two horizontal lines in the picture are Hjørringvej at the top and Sæbybanen at the bottom. The track to the chalk pit can be seen on the right side of the picture. The track to the chalk pit crossed Gl. Kongevej and Hjørringvej in tunnels. The gauge of the factory tracks was 785 mm, the same gauge as the Sulfuric acid factory. The factory was taken over by Aalborg Portland-Cement-Factory and closed in 1935. The last remains of the track between the chalk pit and the factory. The bridge at the crossing of Gl. Kongevej in the year 2002. The tunnel is full but the one railing is still there. The grave and part of the track were taken over by Nørresundby chalk work in 1935 and chalk was dug in the grave several years later. The chalk works closed after 1954.
 The sulfuric acid factory in Nørresundby: the factory was built by ØK 1913–14, but taken over by Danish Sulfuric acid before opening. Approx. 500 m lane for transporting potash from Nørresundby harbor to the factory. They had two steam locomotives and three motor tractors at their disposal. The gauge of the factory tracks was 785 mm, the same gauge as the cement factory. A large number of tipper trucks ran between the factory and the port. The harbor line was shared with the cement factory. During all the years at the factory, these small machines were used. They were built by Arnold Jung in 1914 and lasted until steam was phased out in 1975 at the factory. The two machines are preserved at Hedeland veteran railway. The factory also had standard-gauge industrial tracks as a side track from the Sæby Railway.
 Lindholm brickworks, Brickworks on Lufthavnsvej. Approx. 500 m track between factory and clay pit.
 Lundergaarde, Track from Gug lime factory, which was north of Sdr. Trandersvej down to Hadsundbanen. There was an automatic loading system so that lime could be poured directly into the railway carriages. It seems that the tipper line was closed around 1951, because at that time they sold approx. 2 km of rails and 1-2 engine locomotives. Remains of the impressive cargo facility can still be seen in the terrain. Today, no remains of the industrial railway between the chalk pit and the Hadsund Railway.

Rømøbanen, Kongsmark – Lakolk (Rømø island). Horse	powers, Horsecar 1899-1939.

De Danske Sukkerfabrikker (The Danish Sugar Corporation)da used  gauge railways to transport juice from sugar beets from purpose-built "juice stations"da to the sugar factories in towns such as Nakskov, Lollandda and Maribo sugar factory, Maribo, Lollandda and Højbygaard sugar factory, Holeby, Lollandda and Stege sugar factory, Stegeda and Odense sugar factory, Odense, Funen and Sakskøbing sugar factory, Sakskøbing and Nykøbing Falster sugar factory, Nykøbing Falster, Falster and Assens sugar factory, Assens, Funenda. Around  of  sugar lines existed in 1941 and of which were closed in the 1960s. A few locomotives survived at Bloustrød-banen, and one locomotive was on static display at Assens park until the mid-1990s.da Several towns on the Danish islands have had sugar factories. There have been four factories in Lolland alone. In total, there have been 9 beet sugar factories in Denmark:
 Assens Sugar Factory (1884-2006).da
 Gørlev Sugar Factory (1912-2000).
 Højbygaard Sugar Factory (1873-1960).da
 Maribo Sugar Factory (1897-1962).
 Nakskov Sugar Factory (1882- ).da
 Nykøbing sugar factory (1884- ).
 Stege Sugar Factory (1884-1989).da
 Odense Sugar Factory (1873-1970).
 Sakskøbing Sugar Factory (1910-1991). 
The raw materials were often transported on narrow-gauge railways, so-called beet railways, from the field to the factory. In order to shorten the transport route, some of the sugar factories had associated so-called juice stations, i.e. processing plants that were closer to the cultivated fields. Here, the beet sap was pressed out and then taken in pipelines to the factories. The sugar factories in Stege and Nakskov thus at one time each had five juice stations attached, Assens Sugar Factory had four, and Maribo Sugar Factory had a single juice station located in Stokkemarke. The first Danish beet sugar factory was Højbygaard Sugar Factory in Holeby on Lolland, which was founded in 1872. The factory's last beet campaign was in 1960, after which the buildings were converted into a paper factory. In 2007, the old sugar factory was named one of Denmark's 25 industrial monuments by the Cultural Heritage Agency. Danish Virgin Islands, Danish West Indies sugar plantation and factory narrow railways. There has also been state-supported sugar production based on sugar cane in the Danish West Indies, where the plantations were staffed by slaves. Production today. In Denmark, there are currently approximately 750 farmers who are members of the Danish Sugar Beet Growers Association. They cultivate approximately 33,000 hectares of sugar beet, which results in a production of 2½ million tons of beet. From this, 400-450,000 tons of sugar can be produced annually. The beets are delivered to the two remaining Danish factories, Nykøbing Falster Sukkerfabrik and Nakskov Sukkerfabrik, which each produce around 200,000 tons per year, Both factories are operated by Nordic Sugars, and were fired with 100 MW of heat from coal and oil, which emitted 160-180 thousand tons of  per year. Danisco owned them until 2009, when the sugar division was purchased by German Nordzucker, who named this newly acquired company Nordic Sugars.. Nordic Sugar. The factories' residual waste (pulp and mash) is used to a lesser extent in biogasplants.
 Store Vildmose railway at Store Vildmose-Vildmosemuseet don't exist anymore, only a few materials and only one train remains for preservation on Hedeland veteran railway, (Hedelands Veteranjernbane). Store Vildmose and Lille Vildmose, now a nature reserve a part of Store Vildmose-Natura 2000-area near Vildmosegaard. The railroad was dismantled in 2012, but a 0,4 km museum railway has been established at the Lille Vildmose Museum Center ("Vildmosecenteret")-Vildmosemuseet, Lille Vildmosecentret.
 Kinnerup mergelleje, Hjallerup and the surrounding area's Mergelselskab built this track with support from Hedeselskabet. The locomotive was supplied by Hedeselskabet and was a converted Ford car used before and after at other marl deposits. The line was built in 1930 and closed in 1936. The line ran from Kinneruplejet up to Uggerhalne station, where the marl could be loaded into railcars on the Vodskov – Østervraa railway.
 The peat track around Tylstrup. In the years 1917–22 and 1940–48, the Aalborgense cement factories operated a peat railway with a 700 mm gauge from Tylstrup station to Store Vildmose.

During the First and Second World Wars, narrow-gauge peat tracks were laid out into the wild bog from Tylstrup station. The peats were reloaded at Tylstrup station onto the railway wagons and transported by rail from here to gas plants and electricity plants in Aalborg-Nørresundby. During both wars, the railway facilities had their starting point in Vildmosen and their end point on the east side of Tylstrup station, and both were led under the tracks of the state railway in the same place south of Tylstrup.
Portland Cement A/S acquired in the years 1907–29 10 Krauss steam locomotives, all 785mm gauge; and it must be assumed that some of these locomotives have been used here, although the gauge does not match. The track course was largely the same except that the 1917 version aimed north-west towards the north of Toften and the 1940 version more directly east towards the Damfennerne. There was considerable track construction in the bog; a large part of the collecting tracks were transportable tracks and were used as movable marl tracks after the end of the First War. At both facilities there was a track connection to the engine house in Toughton, where there were workshop, repair and depot facilities. A crossing station was built south of Gammel Vrå, where a permanent track guard changed tracks and set a signal so that inbound and outbound trains could pass each other here. In the summer of 1917 there were approx. 50 men employed on an area as large as 100 td. country, and already at the end of July the first load of peat could be driven to a storage area west of the station in Tylstrup. In the autumn of 1917, DSB gave permission to make an underpass under the track in wood and the peat could now be driven directly to the loading track. After the track to the loading road was established, it was possible to load directly into railway wagons, which made the work more efficient, but since there were 12 mill. peat in the bog and there was great demand and therefore a bypass track for the peat track and a 60 m long loading ramp, 2 m wide and 1 m high were quickly made. The tipping wagons could now tip peat directly into railway wagons, which increased capacity significantly. From the opening of the line in 1917 to the end of May 1920, up to 1,000 railway wagons were loaded, but in 1920 coal prices had fallen so much that the peat digging was no longer economical, and it stopped.
Immediately after the peat track was led to the ramp, the transports picked up speed, and it was not long before the ramp had to be expanded to 2 tip tracks and a loading track on its other side had to be constructed. The loading capacity was thereby doubled and in the period from 1 August 1940 to 31 December 1941, 4338 railway wagons were loaded with peat at the station and Peat unloading at Tylstrup station during the Second World War. Apparently the peats were unloaded next to the DSB wagons and from there loaded into the goods wagons. Despite the large number of loaded wagons, the marshalling was done with the help of horses. The track's traction and stock were small steam locomotives with prairie chimneys with spark arrestors. In 1948 it was over: in 1949-50, the tracks were taken up and the facilities looped. The viaduct under the track was still there until new tracks were added on the Vensysselbanen around 2010. During this renovation, the bridge was removed. Tylstrup station has been demolished, together with the sidings there, and along the east side of the track there is a long strip of peace forest where the track was, and there is no trace of where the track may have gone into the bog. MR trains run over the bridge here in 2005. In connection with the track renewal on the section in 2012, the underpass is filled up and can no longer be seen in the landscape.

Hvorupgaard brickworks (Hvorupgaard teglværk). Built before 1908, on the west side of the DSB line between Nørresundby and Brønderslev. In 1925, a track was laid in a tunnel under the DSB to a clay pit east of the track. The plant closed in the 60s. 600 mm track gauge.
 Nr. Uttrup brickworks at Nørre Uttrup, Approx.  track from clay pit east of the factory to brickworks. Track closed around 1969 due to the construction of a motorway between the factory and the clay pit. Replaced by bridge over motorway.  600 mm track gauge.  
 Aalborg Municipality's renovation works, Aalborg Municipality. Dano incineration plant built in 1952 and closed in connection with the closure of the factory in the early 70s and construction of Reno Nord. The line ran between the renovation works and the current Østeraadal, via a bridge over the Østeraa. In the northern part of Østeraadalen, the forest is planted on incineration waste from the waste disposal factory and brought out via the narrow-gauge railway. Locomotives from Pedershåb. 600 mm track gauge.
 Ringsted brickworks (Ringsted teglværk). 600 mm track gauge.

Greenland, Kingdom of Denmark and The Danish Commonwealth

 The Qoornoq X-press in the village of Qoornoq in the Nuuk fjord was used for transporting fish from the harbour to scaffolds for drying. The railway cars were only. flatbed wagon cars with no locomotives to move them. Hand-worked flatbed wagon cars were used. Built in 1955, the railway was abandoned shortly before the village, around 1971. .

Iceland, Kingdom of Denmark, The Danish Commonwealth 1380-1944

 Korpúlfsstaðir farm railway, Korpúlfsstaðir was one of the first industrial farms in Iceland. Built in 1930 by Icelandic industrialist Thor Jensen, it was located on the outskirts of Reykjavík, on the Þingvellir road. The farm was equipped with a  narrow-gauge railway network, allowing the transportation of goods and materials around the farm site. The rolling stock consisted chiefly of four-wheel skip wagons. There were no operational locomotives during either documented visit to the railway (in 1984 and 1993), and trains were shunted by hand, by the farm's staff. It is not known whether the railway was originally equipped with locomotives. Korpúlfsstaðir Farm has now closed and the site has been developed as a golf course and an elementary school, incorporating most of the original farm buildings. There is no surviving part of this railway network.

Rørdal cement factory, Aalborg Portland – Cement – Factory A/S – Cement-factory in Rørdal The cement factory Rørdal, Second narrowest used on Danish industrial tracks, i.a. at the cement factory Rørdal in Aalborg. Already from the opening in 1891, there were tracks on the factory premises, and they seem to have been tracks of 500 mm gauge. This gauge also existed in 1969. Originally 500 mm tracks with horses, from 1907 several electric lines to pits. From the 20s also 785 mm tracks, just as the track for the chalk pit was rebuilt to 785 mm with 500 V direct current. Until 1945, the track network grew, after which it fell to approx. 30 km in 1965 and approx. 20 km in 1970. The area was also traversed to an equally infiltrating degree by 785 mm gauge tracks. This track system once went all the way to the filling station in the east, but ended in 1970 at the sewage works approx. 800 m east of the factory itself. In the vicinity there were countless track cuts and other track curiosities. There were dual gauge tracks (785/500 and 785/1435 mm), but not all three gauges combined under one. During the Second World War, a more extensive 785 mm track network existed, as a larger track network was laid for the huge peat storage areas. The standard gauge harbor track to Rørdal airfield also branched off from the track in the Rørdal area and continued as a defense track towards the island-lake. :During the years 1907-29 Portland Cement A/S acquired at least 10 Krauss steam locomotives with gauge 785 mm. More have been used at the factory in Rørdal. All these machines were of the  wheel arrangement and Electric locomotive in the chalk pit in the 1920s. In 1970, the  gauge tracks were removed. The  gauge tracks are preserved as a point-to-point track until the mid-70s. The rails for this come from the Sæbyrailway, whose stock of rails etc. was bought by Rørdal. It was a considerable track area the factory had in 1965, it was approx. 30 km and in August 1969 approx. 20 km. At the same time, 33 locomotives were ready for operation.
 Danish Cooperative cement factory, The factory was located on the site of the current Siemens quay in Nørresundby. Docks and a single silo can still be seen. DAC's harbor in Nørresundby 1931. Coal is unloaded at the quay on the right, an accumulator locomotive used on the 500 mm track. The barrels on the left are presumably cement barrels. 3 separate track systems in clay pit, chalk pit and factory with port. Graves and factory were connected by conveyor belts. DAC has not been associated with dump trucks for graves. There were dump trucks in the chalk pit and the first clay pit, but not to the factory. Air bridge for chalk and a channel with natural run for clay. Later replaced by ribbons for chalk and trucks for clay. 3 separate track systems in clay pit, chalk pit and factory with port. The factory also had normal gauge sidings from Nørresundby station.

Faxe Jernbane, gauge unclear
The Faxe Jernbane,  long, was built in 1864 for the transportation of limestone. There is confusion about the track gauge used as various sources mention a track gauge of , but some Krauss steam locomotives delivered in 1927 had the gauge of . Two Schöma locomotives delivered in 1970 had the gauge of  and standard gauge . The railway is now closed.
