Dunedin Railways (formerly the Taieri Gorge Railway) is the trading name of Dunedin Railways Limited, an operator of a railway line and tourist trains based at Dunedin Railway Station in the South Island of New Zealand. The company is a council controlled trading organisation wholly owned by Dunedin City Council through its holding company Dunedin City Holdings Limited.

The Otago Excursion Train Trust was formed in 1978 to operate excursions on the Otago Central Railway line, running its first train in October 1979. The services grew in popularity and the Trust realised by the 1980s that it had great tourist potential. Dunedin City Council then stepped in, purchasing the line as far as Middlemarch and five locomotives, Dunedin City Holdings was a majority shareholder (72.03%) and the Trust held the balance of the shares (27.97%). The company operated as a Council controlled organisation (formerly known as a Local authority trading enterprise) under Part 5 of the Local Government Act 2002. This was due to the need to raise more capital to finance the expansion of the Trusts operation. Dunedin City Council then sold the railway line to the new company, and the Trust sold its locomotives, carriages and other assets to the new company.

The Taieri Gorge Limited is New Zealand's longest tourist railway and stretches along the former Otago Central Railway from the 4 km peg on the Taieri Branch, 18 km west of Dunedin, to Middlemarch, a distance of Between Dunedin and the start of the line, its trains operate on KiwiRail's Main South Line via a running rights agreement. The line travels along the banks of the Taieri River, through numerous tunnels and along the Taieri Gorge to the Strath Taieri. It crosses a dozen viaducts and passes through ten tunnels. At Wingatui railway station, the original building and signal box from 1914 have been restored. After the line passes through the long Salisbury Tunnel, the longest on the line, it crosses Mullocky Gully over the long Wingatui Viaduct, the largest wrought iron structure in New Zealand since it was built in 1887. The 47 m tall viaduct's riveted truss structure rests on seven concrete and masonry piers. Shortly after the Wingatui Viaduct, the route emerges from Mullocky Gully to join Taieri Gorge, and from then on follows that gorge above Taieri River to just east of Pukerangi. On the way the line passes former stations Parera, Mount Allen, Little Mount Allen, and Christmas Creek, crossing two curved viaducts at the latter two locations. Hindon, still operating as a crossing station, is typically one of the stopping points on the trip. Just before the station, the railway tracks share a combined road rail bridge with Hindon Road. Another stopping point for photo opportunities is the Deep Stream viaduct. Here the line slowly starts to climb higher and out of the gorge, passing over the Flat Stream viaduct, and "The Notches", a section of short bridges and cuttings through several rocky outcrops, on its way to Pukerangi. Between Pukerangi and Middlemarch, the railway only once more comes close to the Taieri River, where it crosses Sutton Creek over another combined road rail bridge. Dunedin Railways currently operates on a reduced schedule. The Inlander runs through the Taieri Gorge to Hindon, The Seasider runs up the coast through Waitati to Seacliff, and The Victorian is an all day trip to the North Otago town of Oamaru. Special services also run, including the Christmas Inlander in December and the addition of Quiz Trains in 2023.

Dunedin Railways also operates the Seasider tourist train along the coast to Waitati, north of Dunedin. Following the withdrawal of the Southerner by Tranz Scenic in 2002, it is the only passenger train on the Main South Line. In 2012, Dunedin Railways leased one of the Silver Fern class railcars from KiwiRail for use on the same route as the Seasider.

On 23 October 2014, the Taieri Gorge Railway announced that it would be changing its name to Dunedin Railways. For 35 years, the Taieri Gorge Railway and the Otago Excursion Train Trust had taken tourists on scenic rail excursions up the Taieri Gorge to Middlemarch and more recently up the coast, north of Dunedin on the Seasider. The reason for the change was so that tourists can link the train trips to Dunedin and it makes it much clearer what the railway is. AO 77 was the first carriage to be repainted into their new blue livery with their name on the sides in October 2014. This was followed by A 3022 and AG 239. In September 2015, AL 1695 was repainted into their yellow version of livery.

On 20 April 2020, the company announced that due to the COVID 19 pandemic in New Zealand, it mothballed its track and equipment. The company said up to 80% of its revenue came from international tourists. The mothballing could affect up to 51 jobs.

Following the decision to mothball Dunedin Railways, the Otago Excursion Train Trust sold its shares in the company to the council in April 2020. In May 2021, Dunedin City Council agreed to keep the Taieri Gorge line as far as Hindon in operation, as well as services on KiwiRail's railway lines. In November 2021, the council agreed to extend support through to 2024. In 2023, the council decided to reactivate the Hindon Middlemarch section as well.

In the financial year to June 2017, Dunedin Railways had revenues of NZ$6.578m and expenses of NZ$6.387m, and turned a profit of NZ$137,000. Following the COVID 19 pandemic of 2021, Dunedin Railways was losing NZ$1.5 million per annum. This locomotive was acquired from Otago Polytechnic (who had acquired it from New Zealand Railways Corporation) in the early 1990s and is not mainline certified, instead of being based at the TGR works depot at the 4 km peg. It previously carried a modified International Orange scheme but was repainted in 2006 to its original livery of Carnation Red with the addition of "wasp stripes" on the headstocks as it would have carried in the 1970s. In 2013, Dunedin Railways leased Silver Fern railcar RM24 from KiwiRail and operated this on trips between Dunedin and Waitati. The railcar was returned to KiwiRail in 2019. Dunedin Railways formerly operated a shunting locomotive, TR 111 at their Dunedin depot as their resident shunting locomotive. This locomotive was obtained by the Otago Excursion Train Trust in 2009 from enthusiast Reid McNaught, who had leased the locomotive to Dunedin Railways since 2006. It was sold to the Canterbury Railway Society in July 2015.

All trains as of 2017 include some of Dunedin Railways five former New Zealand Railways 47" 6' foot wooden clad carriages. These cars are known as "Scarrett'" heritage carriages and were built between 1912 and 1923 with open platform ends, gangways and 37 seats. Dunedin Railways has started retiring these carriages largely to provide bogies for their 56 foot carriage stock, which did not have their own bogies when they were purchased. Two of the 47 foot cars have been sold, while two were scrapped circa 1978. One carriage, A 1254, is owned by the Ocean Beach Railway (OBR) and is leased to Dunedin Railways. This carriage will be returned to the OBR at the conclusion of its lease.

Dunedin Railways has currently three steel clad and one wood clad NZR 50 foot carriages, formerly used on Dunedin suburban trains and express passenger trains. The steel clads have 30 37 seats, enclosed vestibules and covered gangways and were built by New Zealand Railways Department in 1931–40. The upgrade included new seating, carpets, toilets and external paint. The railway intends to refurbish three carriages each year. As of December 2015, only five out of the twelve carriages have been restored. Two of these carriages have since been disposed of. In 2012, panoramic window car AO 77 was leased from KiwiRail. It has since been repainted in Dunedin Railways' blue livery and is now under their ownership. Privately owned A 3022 is leased from its owners since 2013. In 2018, Dunedin Railways purchased six big window AO/ASO class carriages from KiwiRail. Two of these have since been converted to all steel framing and reclassified as ADR.

In the early 2000s, the TGR investigated the possibility of introducing log haulage between Mount Allan and Port Chalmers at the end of the Port Chalmers Branch. However, on 12 June 2007, it was announced that a cost difference of NZ$5 million existed between road and rail haulage in favour of road, and potential government subsidies were insufficient to close the gap. The announcement was met with disappointment by the Dunedin City Council, which favourably viewed the rail option as it was more environmentally friendly and would have reduced traffic congestion. It has since been worked out that with extra damage caused by the logging trucks on the Mosgiel to Port Chalmers road that it would have been cheaper to perform the operation by rail, but despite pleas by the local council, Wenita, the relevant company, said it had invested too much in the road option to change its plans. The route's loading gauge restricts the maximum size of rolling stock that can operate on the railway; some freight wagons cannot use the line.
