Supertrain

Whoosh! One hundred and sixty-one miles an hour... 162... 163... 164...

Amtrak's newest passenger train, the Acela Express, seems to fly down the tracks at warp speed. The landscape between New York City and Boston is a blur. Cities and towns whiz by. Cars and trucks motoring down the highway look as if they're standing still.

First in the U.S.

Train transportation in the United States changed forever in November of 2000 when Amtrak launched the Acela Express from New York to Boston. Regular passenger service between Washington, D.C., and Boston began the following month.

Japan and many European countries have had high-speed rail service for years, but the $800 million Acela Express is the first so-called bullet train in the United States.

With the help of government funds, Amtrak built the sleek, bottle-nosed Acela to lure travelers away from automobiles and airplanes.

This 304-passenger train cuts about an hour off train-travel time from New York to Boston. It does this by moving at 150 miles an hour through certain parts of New England. The Acela hit speeds up to 168 mi/h during test runs, but for most of the trip between Washington and Boston it travels at a rate of 135 miles an hour.

Computerized Travel

What makes the Acela so fast? Instead of one locomotive pulling the eight-car train, the Acela has two locomotives. One locomotive is in the front of the train, and the other is located in the back.

Also, engineers designed the train to navigate around curves without slowing down, the way most trains do. Located in the front of the Acela are tiny micro-processors (devices that do the actual computing in a computer) that warn the train when it is speeding into a curve. An onboard computer uses that information to glide the fast-moving train around corners by gently tilting it into the bend. This allows the train to speed around turns while preventing the force of the moving train from knocking passengers around.

Luxury Dining

The Acela is not only the fastest, but is also the most comfortable train in Amtrak's fleet. The restrooms are spacious. People can turn their seats around to talk to other passengers. Amtrak treats passengers traveling in first class to full-course meals.

A former presidential candidate, Michael Dukakis, who is now vice chairman of Amtrak, said the Acela “is the future, [and] we've seen it.”

Activity

Amtrak made up the name “Acela” by putting parts of two English words together.

  • The word accelerate means gain speed, or go faster.
  • The word excellence means the condition of being superior.

Imagine that you have been hired to name a new form of transportation. Write a paragraph to describe this new transportation. Be as creative as you wish.

Next, choose 2 words that you would like to use to describe your new transportation. Combine the words to form a new name for your idea.

Data Hunt

Less than 1 percent of U.S. travelers go from city to city by train. Most drive cars or take a plane.

Model airplanes are exact copies of actual planes, only much smaller. Models are available for commercial planes—the ones we ride on—and for military, cargo, and privately owned planes.

All model planes are built to scale. The bigger the actual airplane, the smaller the scale. The table gives the sizes of the models of three commercial planes and three army air corps planes.
