RoometteA roomette is a type of sleeping car compartment in a railroad passenger train. The term was first used in North America, and was later carried over into Australia and New Zealand. Roomette rooms are relatively small, and were originally generally intended for use by a single person; contemporary roomettes on Amtrak, however, include two sleeping berths. In Australia, a roomette is designed for use by one person. The width of each compartment is typically slightly less than half the width of the sleeping car it is in, with a corridor running down the centre and the compartments on both sides.
Locomotive à turbine à gazLes locomotives à turbine à gaz ont été mises au point dans plusieurs pays au . Elles utilisent une turbine à gaz analogue à celle que l'on rencontre dans les avions ou les hélicoptères pour entraîner un axe de sortie. La transmission rencontre alors à peu près les mêmes contraintes que pour les locomotives Diesel et on observe les mêmes solutions : transmission mécanique, électrique (semblable à la solution Diesel-électrique) ou hydraulique.
AmfleetAmfleet is a fleet of single-level intercity railroad passenger cars built by the Budd Company for American company Amtrak in the late 1970s and early 1980s. Budd based the Amfleet design on its earlier Metroliner electric multiple unit. An initial order for 57 cars in 1973 to supplement the Metroliners on the Northeast Corridor grew to two orders totaling 642 cars, sufficient to reequip all the services on the Northeast Corridor and many other routes around the United States.
AmtrakAmtrak (sigle de l'AAR : AMTK) est une entreprise ferroviaire publique américaine, spécialisée dans le transport de voyageurs. Le nom d'Amtrak a été créé par la contraction des mots anglais AMerica et TRAcK (« la voie ferrée »). Sa dénomination officielle est National Railroad Passenger Corporation (Société nationale du transport ferroviaire de voyageurs), Amtrak étant son nom commercial. Amtrak est née le de la fusion des services voyageurs de 20 compagnies ferroviaires différentes.
Higher-speed railHigher-speed rail (HrSR), also known as high-performance rail, higher-performance rail, semi-high-speed rail or almost-high-speed rail, is the jargon used to describe inter-city passenger rail services that have top speeds of more than conventional rail but are not high enough to be called high-speed rail services. The term is also used by planners to identify the incremental rail improvements to increase train speeds and reduce travel time as alternatives to larger efforts to create or expand the high-speed rail networks.
