This first electrification system with GE-built boxcabs were the only three-phase AC power ever used on North America railroads, see Three-phase AC railway electrification. The electric boxcabs pulled trains through the tunnel with their steam locomotives still attached until they were retired in 1927.
The system is also known as the Southend Electrification, in contrast to Amtrak's 60 Hz traction power system that runs between Boston and New Haven, which is known as the Northend Electrification system. In 1976, Amtrak inherited the system from Penn Central, the successor to the Pennsylvania Railroad, along with the rest of the NEC ...
Third-rail electrification between Hartford, New Britain, and Berlin, a total of 12 mi (20 km) in 1896. This third-rail system was unique; it consisted of an inverted V cross-section rail, mounted on the cross ties between the running rails, and was totally exposed. In 1898, the New Canaan Branch was electrified with 500V DC catenary. [1]
Another factor complicating electrification work in the Boston Terminal Area is the large volume of rail traffic. Over 250 Massachusetts Bay Transportation Authority (MBTA) commuter trains and 20 Amtrak trains operate through the area daily. As a result, taking track out of service to work on the electrification was sometimes difficult.
Railway electrification is the development of powering trains and locomotives using electricity instead of diesel or steam power.The history of railway electrification dates back to the late 19th century when the first electric tramways were introduced in cities like Berlin, London, and New York City.
The electrification was extended to include the Fox Chase Line in September 1966. Electrification was again extended from Hatboro to Warminster in the early 1970s. [1] [page needed] The Reading's system used catenary electrified at 12 kV 25 Hz like the competing Pennsylvania Railroad's 1915
The Caltrain Modernization Program (CalMod), sometimes referred to as the Caltrain Electrification Project, was a $2.44 billion project which added a positive train control (PTC) system and electrified the main line of the U.S. commuter railroad Caltrain, which serves cities in the San Francisco Peninsula and Silicon Valley.
