Amtrak runs Shuttles between Springfield, Massachusetts and New Haven, Connecticut along Amtrak's New Haven–Springfield Line. These shuttles connect with Northeast Regional service at the New Haven station, usually a cross-platform or same platform transfer. The Shuttles are numbered in the 400 series, usually denoting by the last two digits which Regional train the train is connecting with. Typical consists run in push-pull configuration with a GE Genesis locomotive pulling an Amfleet coach and a 9600 series Metroliner cab car. Normally the Ex-Budd Metroliner leads northbound trains, while the GE Genesis usually leads most southbound trains. Crew bases are at Springfield and New Haven, with diesel locomotive servicing taking place at New Haven. During fiscal year 2011, the Shuttle service carried over 380,000 passengers, an increase of 4.8% over FY2010. The service had a total revenue of $11,204,575 in FY2011, a 9% increase over FY2010.〔 ==History== Until electrification was extended to Boston along the Shore Line portion of the Northeast Corridor (NEC) in 2000, Springfield Shuttle trains operated as "sections" of regular NortheastDirect trains. New Haven marked the end of electrification which required an engine change for all Amtrak trains passing through. On trains going to Boston, one or two cars would be uncoupled from the rear, containing the passengers wishing to travel through to points between New Haven and Springfield. After the Boston portion of the train continued along its way, a diesel engine would attach to the left-behind cars and pull them to Springfield. Trains from Springfield would platform, then pull forward to a relay track, leaving the passenger cars to wait for the train to arrive from Boston. An electric locomotive would then couple to the Springfield cars and push them onto the front of the arriving southbound train. When the power change was eliminated at New Haven, this cumbersome splitting and re-combination procedure was abandoned in favor of a dedicated shuttle train that would meet each through train at the same platform. Former Metroliner cab cars were obtained from other parts of the system, and the Shuttles began to operate in push-pull format, eliminating the need to wye or loop the trainsets at New Haven and Springfield. The new Amtrak president, David L. Gunn then re-launched the Springfield Shuttle service with increased number of round trips and much-lower "commuter" level fares, turning the shuttle into a service in its own right, instead of just a connection for through travelers along the Northeast Corridor. Until August 2015, daily service in each direction on the Springfield Line consisted of 4 Shuttles, the ''Vermonter'', and one to two ''Northeast Regional'' trains. Beginning on August 3, 2015, three of the Shuttle round trips on weekdays were replaced by buses to accommodate double track construction for the Hartford Line commuter service. The busing will last for approximately one year, shortly after which the start of Hartford Line service will supplement Amtrak service with an additional eleven daily round trips south of Hartford and five additional trips north of Hartford. Weekend service remains as normal. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「New Haven–Springfield Shuttle」の詳細全文を読む スポンサード リンク
