What I like about the design of this mall is how the food court level is split between the lower and upper levels. It would make it more difficult to expand the.
Technical. Track gauge. Operating speed. 15. The Acela Express (ə- SEL- ə; colloquially abbreviated to Acela) is Amtrak's flagship service along the Northeast Corridor (NEC) in the Northeast United States between Washington, D. C. and Boston via 1. Baltimore, Philadelphia, and New York City.
The route contains segments of high- speed rail, and Acela Express trains are the fastest trainsets in the Americas; they attain 1. Acela carried more than 3. Northeast Regional, which had over 8 million passengers in FY 2. Its 2. 01. 5 revenue of $5. Amtrak's total. (Another 2. Northeast Regional traffic, and roughly 2. Acela operates along routes that are used by freight and slower regional passenger traffic, and only reaches the maximum allowed speed of the tracks along some sections, with the fastest peak speed along segments between Mansfield, Massachusetts and Richmond, Rhode Island.
Acela trains use tilting technology, which helps control lateral centrifugal forces, allowing the train to travel at higher speeds on the sharply curved NEC without disturbing passengers.[1. The high- speed operation occurs mostly along the 2. New York's Penn Station to Washington DC's Union Station, with a fastest scheduled time of 2 hours and 4. Over this route, Acela and the Northeast Regional line captured a 7. New York and Washington in 2. Due to this competition, one airline canceled service between Washington and New York.[1. The Acela's speed is limited by traffic and infrastructure on the route's northern half.
On the 2. 31- mile (3. Boston's South Station to New York's Penn Station, the scheduled time is 3 hours and 4. Along this section, Acela has still captured a 5. The entire 4. 57- mile (7. Boston to Washington takes 7 hours,[2] at an average of around 6. The present Acela Express equipment will be replaced by new Avelia Liberty trainsets beginning in 2. Amtrak will retire all current trains by the end of 2.
History[edit]Background[edit]. The X2. 00. 0 during testing by Amtrak. Following the success of Japan's newly inaugurated Shinkansen network, the High Speed Ground Transportation Act of 1. U. S. government to explore the creation of high- speed rail, which resulted in the introduction of Metroliner trains, the predecessor to Acela.
During the 1. 98. US Federal Railroad Administration explored the possibilities of high- speed rail in the United States. On December 1. 8, 1. Intermodal Surface Transportation Efficiency Act of 1. ISTEA) (PL 1. 02- 2. Northeast Corridor.[1.
Amtrak asked railway equipment manufacturers to submit proposals. An X 2. 00. 0 train was leased from Sweden for test runs from October 1. January 1. 99. 3. It was operated from Washington DC to New York City from February to May and August to September 1.
Siemens showed the ICE 1 train from Germany, organizing the ICE Train North America Tour which started to operate on the Northeast Corridor on July 3, 1. This testing allowed Amtrak to define a set of specifications that went into a public tender in October 1. Building and development[edit]On March 9, 1. Amtrak unveiled its plan for a high- speed train, the Acela Express.[1. Twenty new trains were to run on the Northeast Corridor.[1. Several changes were made to the corridor to make it suitable for the Acela.
The Northend Electrification Project extended existing electrification from New Haven to Boston to complete the overhead power supply along the 4. In October 1. 99. Amtrak requested bids from train manufacturers for a trainset that could reach 1. A joint project of Bombardier (7. GEC Alsthom (now Alstom) (2. March 1. 99. 6.[8] An inaugural VIP run of the Acela came on November 1. December 1. 1, a few months after the intended date.[2.
Then- Vice President Joe Biden and Senator Arlen Specter riding the Acela Express to Philadelphia in February 2. By 2. 00. 5, Amtrak's share of the common- carrier market between New York and Boston had reached 4. Acela.[2. 4] With the increasing popularity of the faster, modern Acela Express, Metroliner service was phased out in late 2. To meet the demand, more Acela services were added in September 2.
By August 2. 00. 8 crowding had become noticeable.[2. By 2. 01. 1, the Acela fleet had reached half of its designed service life. Amtrak proposed several replacement options, including one as part of its A Vision for High- Speed Rail in the Northeast Corridor.[2.
In 2. 01. 1, Amtrak announced that forty new Acela coaches would be ordered in 2. The existing trains would have received two more coaches, lengthening the trainsets from a 1- 6- 1 configuration to 1- 8- 1 (power car - passenger cars - power car). The longer trainsets would have required the modifications of the Acela maintenance facilities in Boston, New York and Washington.
The first of the stretched trainsets was to have entered service in fiscal year 2. This plan was cancelled in 2. Acela fleet.[3. 1]In January 2. Amtrak issued a request for proposals on 2.
Acela trainsets, in a combined order with the California High- Speed Rail Authority. These bids were due May 1. After discussions with manufacturers, Amtrak and the California High Speed Rail Authority concluded their needs were too disparate for common rolling stock and decided not to pursue the joint option.[3. Amtrak's original contract with the Bombardier- Alstom consortium was for the delivery of 2. By 2. 00. 4, Amtrak had settled contract disputes with the consortium, paying a total of $1. Boston, New York, and Washington.[3. Speed limits[edit]Acela Express's fastest schedule between New York and Washington DC was 2 hours and 4.
President Barack Obama's administration to replace catenary and upgrade signals[3. Trenton and New Brunswick, which will allow speeds of 1.
This section of track holds the record for the highest speed by a train in the US, which is 1. U. S./Canada- built UAC Turbo. Train on December 2. In practice, the Acela's speed depends more on local restrictions along its corridor than on its trainset. In addition to speed restrictions through urban areas, the Acela's corridor includes several speed restrictions below 6.
Altogether, Amtrak has identified 2. Acela's route that are beyond their design life.[4.
Branding[edit]The Acela name was announced on March 9, 1. Amtrak originally intended for this move to be part of a rebranding of the majority of their Northeast services,[4. Acela Express, Acela Regional, and Acela Commuter.[4. The branding team based the name "Acela" on the ideas of acceleration and excellence.[4. There were then three classes of trains on the Northeast Corridor (and its extension south to Newport News, Virginia)— Philadelphia- New York Clockers, the express Metroliners, and the umbrella term. Northeast. Direct, applied to other trains on the corridor (in addition to unique names assigned to each departure).
Empire Service trains used the Empire Corridor from New York City to Niagara Falls, and Keystone Service ran along the Keystone Corridor from Philadelphia to Harrisburg. The Acela Regional name was first applied to Northeast. Direct trains 1. 30–1. January 3. 1, 2. 00. Those trains, 1. 30 and 1. Northeast Corridor.[4.
As more trains were electrified, they too were rebranded.
