History

NIR was formed in 1968 when it took over from the Ulster Transport Authority

The Ulster Transport Authority ran rail and bus transport in Northern Ireland from 1948 until 1966.The UTA was formed by the 1948 Transport Act , which merged the Northern Ireland Road Transport Board and the Belfast and County Down Railway ....
 (UTA), which had operated the province's railways since 1948. Much of the railway network closed during the 1950s and 1960s, declining from 900 miles (1,500 km) to 206.61  miles (330.58 km) at present.

Suffering frequent disruption and damage to infrastructure caused by the Troubles, and starved of investment by successive political administrations, the NIR network had become badly run down by the 1960s, with old rolling stock and poorly maintained track. NIR's last steam locomotives were withdrawn in 1970.

In 1970, NIR started using new rolling stock to re-launch the once popular Enterprise

As older trains became obsolete in the 1970s, a new type of diesel-electric multiple unit was introduced to the network, called the Class 80

By the early 1970?s the MED?s and units inherited from the Great Northern Railway had been in service for 20 years, and the MPD?s for 10 years. With reliability becoming a problem the new Class 80 diesel electric multiple units were ordered from British Rail Engineering Limited....

Rolling stock


Current fleet

Since the 1950s, services in Northern Ireland have been mainly operated by diesel-electric multiple units rather than locomotive hauled stock. Today, NIR operates three distinct types of DEMU. These are supplemented by a single rake of locomotive hauled stock, which is pulled by one of NIR's three diesel locomotives.

In 2007, NIR announced plans to purchase up to 20 new trains under its "New Trains 2010" proposal following the confirmation of its expected budget. It is planned that this fleet will replace the remaining 80 Class and 450 Class trains from 2011. Renamed as "New Trains Two", this project went out to tender in late 2007, with the company due to be appointed in early 2009. Work on the new trains would begin shortly thereafter with the units entering service from 2011 onwards.

 requested additional funding to cover the costs of rising fuel bills and maintenance, in part due to the global financial downturn. In the event of additional funding being unavailable, NIR made a number of suggestions to absorb the rising costs, which included the end of Sunday train services, or stopping services after 2200 on weekdays.

New Timetable


As of 14th December 2008, a new timetable will come into effect. This will be rather similar to the old timetable with the odd service being shifted by up to 2 minutes. On the Londonderry line, the early morning and late night service will start and end at Coleraine, possibly due to lack of demand for this service. However the latest service still leaves Belfast Central at 21.25, meaning passengers travelling to Ballymena and Antrim are restricted from travelling later at night.

Future

The development of the railways in Northern Ireland has been linked to the future economic growth of the region. One of the major challenges which NI Railways has faced is the limited number of trains available for service at peak times. The limited fleet size has led to services being cancelled due to failures or delays. This can lead to widespread disruption across the network and potentially a huge loss in revenue to Translink. Upon its establishment in 1998, the Northern Ireland Assembly

 put in place an investment programme costing £100 million to bring about major improvements to the railways. This programme saw various projects including the purchase of the new 3000 Class trains, the complete relaying of track on the Belfast-Larne line

 and the construction of a new maintenance depot. Following the completion of this, Translink, as part of its long-term investment programme for NIR, conducted what it termed the "Strategic Rail Review" in 2004, an independent review of rail services to determine its funding request under the Comprehensive Spending Review. This report determined that so-called "lesser used lines" were an important and economically viable part of the total network, and that investment should be consistent rather than in the "stop-go" manner of previous years.

Further proposals from external pressure groups have advocated the protection of former routes, where the track has been lifted but the trackbed remains intact, to enable these routes to be reinstated in the future in the event of the growth of commuter traffic as an alternative to increased road building.

The reopening of the Lisburn-Antrim line is seen not simply in terms of provision of a link to the airport however - it would also allow for the further economic development of the area, which has seen increases in population as people use the towns in South Antrim as dormitary settlements for Belfast. Additionally, the Belfast Metropolitan Area Plan 2015 identifies the need to improve transport links to Belfast City Airport from the city centre. The BMAP proposed a light rail

 retail development. However, in April 2008, the decision was taken not to proceed with the light rail project, with the DRD instead choosing to implement a new bus based network.

Instead they propose that, instead of the Tillysburn station, which will still be some distance from the airport terminal, providing rail links to the airport, a dedicated airport station, similar to Prestiwck Airport, should be connected directly to the terminal, with Tillysburn located half a mile away serving Holywood Exchange.

This will involve the refurbishment of up to three 4-car Class 80 units, and the conversion of the locomotives and coaches to push-pull operation with the addition of the DBSO obtained from 'one'.

One of the major projects instigated by Translink is what it calls "New Trains Two" (formerly "New Trains 2010"), which will see the purchase of a new batch of rolling stock. At minimum, this was to be a like for like replacement of the Class 450

The specification given by the DRD also states that the new trains are to be used to provide both inner and outer suburban commuter services and express services between Belfast and Dublin. The new rolling stock is estimated to enter service by 2011. According to latest developments, it is expected that the new trains will be four carriages in length to allow for extra passengers as two 3-carriage trains can prove somewhat unsatisfactory in that there is no gangway between the trains.
