LRC (train)

LRC is a bilingual acronym for Light, Rapid, Comfortable or Léger, Rapide, et Confortable, the name of a series of lightweight diesel-powered passenger trains that are currently used on short- to medium-distance inter-city service in the Canadian Provinces of Ontario and Quebec. The LRC family includes both locomotives and passenger carriages designed to work together, though the two can be, and now are, used separately.

The trains were intended to increase the speed of passenger train service over conventional non-high-speed railway tracks. They do this using active-tilt technology to reduce the forces acting on passengers when a train travels at higher speeds around a curve in the railway tracks, and thus increase passenger comfort without the need to build new, straighter tracks as is required for high-speed trains such as France's TGV and Germany's ICE. The LRC is the oldest tilting train still in service.

Initially, the LRCs were plagued with problems. One common problem was that the cars would ‘lock’ in the tilted positioned even after the track had straightened out from a curve. The locomotives were never designed to tilt.

LRCs have reached speeds as high as 208 km/h (130 mph) on test runs, but signalling limitations generally restricted them to more conventional speeds in practical operation. The fastest operating speed today, in the Quebec City-Windsor Corridor is about 160 km/h (100 mph), making them the fastest trains in Canada. Many sections of the corridor are signed for a special, higher speed when the LRC's tilting system is activated.

Developed initially by Montreal Locomotive Works and Alcan with the assistance of the Government of Canada and the Canadian National Railway, they were commercialised in the 1980s after Bombardier acquired Montreal Locomotive Works.

LRC trains have been operated by the continent's two major present-day passenger railways, VIA Rail in Canada and Amtrak in the United States. Amtrak returned their leased trains after extensive testing and experimental service between Boston and New York, but VIA Rail put the trains into service, persisting through their initial teething pains and coming to depend on the LRC for the majority of VIA’s intercity service in the Quebec City-Windsor Corridor. The original LRC locomotives were gradually retired after ten to fifteen years of service (although #6905 was used during test runs of the Nightstar ‘Renaissance’ carriages between Glen Robertson and Ottawa in 2000).

LRC Carriages

Most of the carriages remained in service after the withdrawal of the LRC locomotives, though pulled by newer locomotives, usually P42DCs and often with the tilting mechanism disabled. From 2003 onwards, VIA installed wireless internet on all Corridor trains, with distinctive white domes for the satellite uplink being installed on top of the first class carriages. A new capital programme announced by the Canadian government in October 2007 includes funding for the refurbishment of VIA's remaining LRC carriages.

Bombardier have since used updated versions of the LRC carriages and their tilt systems in the Acela Express electric high-speed trains they developed for Amtrak in the late 1990s, the Super Voyager in the United Kingdom [cite news |publisher=Railway Gazette International |title=Super Voyager completes tilt trials in France |date=2002-03-01 |url=http://www.railwaygazette.com/news_view/article/2002/03/1492/super_voyager_completes_tilt_trials_in_france.html |accessdate=2007-11-02] , and in the experimental JetTrain recently proposed for several corridors in Canada and the United States.
