In March 2005 the passenger division of BK Tåg went bankrupt. The services operated by them (the Krösatågen network centered around Nässjö and Linköping-Kalmar/Västervik) were suspended.

It was formed by the privatisation of British Rail in 1996 and it operates train mainline services from Marylebone station in London, to Aylesbury and Birmingham Snow Hill. Initially the line was franchised to a company formed by the British Rail managers of the route, but since 2003 has been a wholly owned subsidiary of Laing Rail, who owned a much smaller shareholding at privatisation. In 2002 a new 20 year franchise began which promises significant investment in the route. | http://www.chilternrailways.co.uk/ | |

| CMLR | | GB: United Kingdom | N: Narrow gauge railway | | Campbeltown and Macrihanish Light Railway | The Campbeltown and Macrihanish Light Railway was a 2' 3\" gauge line at the end of the Mull of Kintyre in Scotland. It had its origins as a coal carrier from the pits at Drumlemble to the quays at Campbeltown, but during the era of the Clyde steamers, Campbeltown became a very popular destination for day trippers and the railway capitalised on this by extending itself to Macrihanish offering access to the Atlantic Ocean and the local golf links! Its final length was about 6 miles. The line originally opened for coal traffic in 1877, and for passenger traffic through to Macrihanish in 1906. It then led a relatively prosperous life until after the first world war, but succumbed to the inevitable road transport, closure of the pits and changing holiday patterns in 1931. It was independent throughout its existence. The railway was interesting in that its coaches were enormous for such a small gauge, and that the early coal trains consisted of 2ft 3in gauge transporter wagons carrying 4 small colliery wagons known as "hutches", transversely. | | |

| DRS | | GB: United Kingdom | R: Railway | | Direct Rail Services | Direct Rail Services (DRS) is a freight operating company created by British Nuclear Fuels Limited. The company started rail operations in 1995 using heavily refurbished Class 20/3 diesel locomotives. Since then it has expanded greatly, and has acquired many more locomotives, most bought second-hand and subsequently refurbished. Ownership of DRS was transferred from BNFL to the Nuclear Decommissioning Authority when the NDA was created on 1 April 2005, under the terms of the Energy Act 2004. DRS remains unique in Britain, remaining a publicly-owned rail freight company. DRS now operates all nuclear-flask trains in the country. | http://www.directrailservices.com/ | |

| FFEST | | GB: United Kingdom | N: Narrow gauge railway | | Ffestiniog Railway | The Ffestiniog Railway is a 2ft (nom.) gauge railway in North Wales. It is probably the most famous and influential narrow gauge railway in the world! The railway was built to carry slate from the quarries in Blaenau Ffestiniog to the quays in Porthmadog. Without the railway it is doubtful that either of these places would have developed anywhere near to the extent they have today. At first a mixture of horse and gravity power was used, but horses were later replaced by steam power. The railway operated continuously from 1836 until it closed in 1946. It now operates as a preserved tourist line, reopening in stages from 1954 until 1982. | | |

| FL | | GB: United Kingdom | R: Railway | | Freightliner (GB) | Freightliner is a British freight operating company, founded in 1995. It is the second largest railfreight operator, after EWS. The origins of the Freightliner concept go back to the mid-1960's British Rail under Richard Beeching. As part of an overall modernisation and rationalisation programme, British Rail began moving freight using ISO containers on flat wagons between a series of dedicated inland terminals using gantry cranes for transhipment from road to rail. Although initially intended for domestic freight, this was soon overtaken by freight between deep sea ports, such as Southampton Maritime an and inland distribution terminals associated with centres of manufacturing or population such as Birmingham Landor Street. In 1995, Freightliner was privatised as a stand alone company, being bought out by its own management. | http://www.freightliner.co.uk/ | |

| GJPR | | GB: United Kingdom | N: Narrow gauge railway | | Gorseddau Junction and Portmadoc Railway | The GJ&PR was built in the wake of the successful Ffestiniog Railway and Croesor Tramway to bring slate and metal ores down from the remote Pennant Valley to the quays at Porthmadog, a distance of about 13 miles. It was an expansion of an earlier 3ft gauge line and involved reducing the gauge to 2ft (nom.) in line with its neighbours. It was expected to lead to the expansion of quarrying and mining at the head of the Pennant Valley, but unlike the Blaenau Ffestiniog region, little useful material was found and the quarries and therefore the railway were all spectacularly unsuccessful. The railway was active from 1875 to 1892, and due to the remote country through which it ran most of the trackbed is still intact. | | |

| GW | GWR | GB: United Kingdom | R: Railway | | Great Western Railway | The Great Western Railway (GWR) was a British railway company and a marvel of civil engineering, linking South West England, the West Country and South Wales with London. It was founded in 1833, kept its identity through the 1923 grouping, and became part of British Railways at nationalisation in 1948. Known admiringly to some as "God's Wonderful Railway", jocularly to others as the "Great Way Round" (some of its earliest routes were not the most direct), and by some as the "Goes When Ready" due to the casual way in which some of its branch lines were run, it gained great fame as the "Holiday Railway", taking huge numbers of people to resorts in the southwest. | http://en.wikipedia.org/wiki/Great_Western_Railway | |

| LMVLR | | GB: United Kingdom | N: Narrow gauge railway | | Leek and Manifold Valley Light Railway | The L&MVLR was a 2' 6\" gauge line in Derbyshire, England. It ran through picturesque but rural country, with a very sparse population to sustain it, from Waterhouses (at the end of the North Staffordshire Railway's branch from Leek) to Hulme End, a distance of just over 8 miles. The line opened in 1904 and was operated by the NSR, until both were absorbed into the London, Midland and Scottish Railway in 1923. The LMS continued to operate it at an ever increasing loss due to competition from road transport until finally, in 1934, the dairy that was its main source of traffic closed, and the railway itself soon succumbed. All was not lost, however, because the local council ensured that most of the track-bed was retained as a cycle-way and footpath, and thus can still be enjoyed today. | | |

It was conceived as both a mineral carrier and to catch the local day-trip trade, although for nearly all its life it has existed only as a tourist railway. It opened in 1902 as an independent company but with strong interest from the Cambrian Railways, it became part of the Great Western Railway in 1923, and then British Railways. It holds the distinctions of being the last part of BR to use steam, and was the first part to be privatised. | | |

| SP | | USA: United States | R: Railway | | Southern Pacific | Southern (New Southern Railway Ltd.) is the latest name of the train operating company that took over from Connex South Central on the routes to South London, Surrey, and Sussex from Victoria and London Bridge. The company was originally known as South Central, but on 30 May 2004, the franchise was rebranded as Southern, in a deliberate recollection of pre-nationalisation Southern Railway. Southern also operates the cross-London Watford Junction to Gatwick Airport / Brighton route via Kensington (Olympia) and Clapham Junction (the West London Line). The franchise is owned by Govia, a joint venture between transport groups Go-Ahead Group and Keolis. | http://www.southernrailway.com/ | |

| VIR | VT | GB: United Kingdom | R: Railway | | Virgin Trains Ltd. | 1999: 3733km standard gauge, electrified at 25kV 50Hz Virgin Trains is a train operating company in the United Kingdom. It is generally considered part of the Virgin Group, although the shareholding is actually split 51:49 between Virgin Group and Stagecoach Group. The company was formed to take advantage of the privatisation of British Rail in the mid 1990s. Virgin Trains were successful in the bids for two franchises, the first being to run express train services on the West Coast Main Line (WCML). This part of the company is called Virgin West Coast (VWC) and provides services from London Euston to the West Midlands, the North West and Scotland. The other franchise Virgin Trains obtained is called Virgin Cross-Country (VXC - see also Cross Country Route) and runs long distance services which by-pass London and link the south and south-west of England with the north of England and Scotland via Birmingham. Unlike most other train operating companies, Virgin operates the two franchises as a single brand, although legally and operationally, they are separate companies. | http://www.virgintrains.co.uk/ | |

| WLL | | GB: United Kingdom | N: Narrow gauge railway | | Welshpool and Llanfair Light Railway | The Welshpool and Llanfair Light Railway is a 2' 6\" gauge line in rural Wales. It was conceived as a general carrier and passenger railway, but mainly carried agricultural produce from the local farms along the route from Llanfair Caereinion down to the mainline and canal at Welshpool, a distance of about 9 miles. The line opened in 1903, and was operated from the outset by the Cambrian Railways. It came into the GWR fold at the 1923 grouping. The passenger service was suspended in 1931 and the coaches later scrapped. The GWR rebuilt ("Swindonised") the locos as was their habit and supplied some more goods stock and the railway settled down into a bucolic existence serving the local farming community. It became part of British Railways and was finally closed in 1956. The railway was then taken over by a preservation society and since 1960 has progressively reopened from Llanfair. In the early 1980s, the railway once more reached the outskirts of Welshpool at Raven Square. | | |
