"Acela" is a
brandapplied by Amtrakto its high-speed trains along the Northeast Corridorin the Northeast U.S., called " Acela Express". Prior to 2003, the " Acela Regional" name was applied to most local trains on the corridor, now called "Northeast Regional" to avoid confusion. The "Acela Commuter" name was proposed but never used for the "Clockers", and "Acela Regional" was planned for all trains on the Empire Corridorand Keystone Corridorin addition to the Northeast Corridor. In fiscal year2006, a total of 2,668,174 passengers rode Acela, an 8.8% year-over-year increase.

On March 9, 1999, Amtrak unveiled its design for its new high-speed service, and announced that most services in the Northeast would be branded "Acela". The name was a
portmanteauof "excellence" and "acceleration", pronounced "ah-cel-la" [ə'sɛlə] (though a great many riders and staff call it "ack-cel-la" [ək'sɛlə] , in keeping with the name's derivation). At that time, there were three classes of trains on the Northeast Corridor (and its extension south to Newport News, Virginia) — the hourly Philadelphia-New York "Clockers", the express " Metroliners", and the umbrella term" NortheastDirect", applied to all other local trains on the corridor (in addition to unique names assigned to each departure). "Empire Service" trains used the Empire Corridorfrom New York Cityto Niagara Falls, and " Keystone Service" ran along the Keystone Corridorfrom Philadelphia to Harrisburg. Other named trains also used the corridors, branching off or continuing beyond their stations.
As announced, the original plan was to rebrand all services but those continuing beyond the termini as "Acela". The "
Metroliners" would be replaced with " Acela Express". All " NortheastDirect", "Empire Service" and " Keystone Service" trains would become " Acela Regional". Finally, the "Clockers" would be " Acela Commuter".

In practice, the "
Acela Regional" name was first applied to " NortheastDirect" trains 130-133 on January 31, 2000. Those trains, 130 and 131 running weekdays only and 132 and 133 running every day, were the first electrified trains to run on the full Northeast Corridor.

[Bob Johnston, Acela Express begins; NEC schedules revamped, "Trains" January 2001] On March 17, 2003 the "Acela" name was dropped from the " Acela Regional", with the trains simply being called "Regional". Technical difficulties have led to a joke about Acela standing for "Amtrak Customers Extremely Late Again" trains. [ [http://host18.hrwebservices.net/~myjackp/mar2303.html Rail Travel News - News Posting March 23, 2003] ] The "Acela Commuter" service never appeared. It simply remained known as the "Clocker" service up until October 28, 2005, when it was discontinued and New Jersey Transitintroduced four new express trains between Trenton, NJand New York City to make up for the lost service.
Comparison of speed
Although the Acela is marketed as a high speed train, in reality it is not much faster than standard speed service. For example, at an average speed of 86 miles per hour, it is not significantly faster than the
Denver Zephyrservice that ran at an average speed of 77 mph between Chicago and Denver in the early 1960s.
In comparison, other high speed trains around the world are much faster.
Japan's Shinkansentrains average more than 125 mph. France’s high speed TGVtrains average 173 mph, Germany’s high speed trains average 153 mph, and South Korea’s averages 125 mph. [ [http://republicans.transportation.house.gov/news/PRArticle.aspx?NewsID=305 Committee on Transportation and Infrastructure - U.S. Rep. John L. Mica] ]
The lack of speed is explained primarily by the long-term under funding of rail infrastructure in the US compared with other developed nations, and the lack of political will to upgrade existing train tracks and catenary. High speed rail travel requires both "tilting train" technology for the comfort of passengers and constant-tension catenary to keep the train powered.
Tilting enables passengers to ride comfortably on curved sections of track faster than would otherwise be possible, by leaning into the bend. The technology has been implemented on other service lines such the
Virgin Trains Pendolino British Rail Class 390trains which run at a speed of 125mph (soon upgrading to 140mph) on Britain's Victorianera rail lines. Many segments of track in of the Northeast Corridor south of New York are too close together for the carriages to safely tilt while maintaining FRAminimum space between locomotives on parallel tracks. While the system was originally designed for a 6.8° tilt, the cars were redesigned 4 inches wider to accommodate wider seats and aisles that reduced the tilt to a more modest 4.2° which still fits within the clearance constraints of the existing tracks. [http://www.washingtonpost.com/wp-srv/travel/features/acelaflash.htm Inside the Acela] Travelling at 150 mph and higher also requires constant-tension catenary which is only implemented on relatively more modern catenary system north of New York.
If the Acela were upgraded to an average speed of 125mph, the current six and a half hour journey between Boston and Washington, D.C. would be just under four hours and 45 minutes.dubious
