In particular was the 1.4-mile long Howard Street Tunnel, which passed directly beneath the city. Perhaps most interesting is that it leaned heavily on the work of early streetcar/interurban operations. Components for the 600-volt, direct current (DC) system were provided by General Electric including the original three, steeple-cab locomotives capable of producing 360 horsepower via four gearless motors. The Belt Line opened on May 1, 1895 although initially employed coke-fired steam locomotives (which produced less smoke) until the electrics had arrived on June 27th. Electrification officially launched on July 1st, originally featuring overhead catenary (energized wires for electrical pickup, strung above the roadbed and supported by trolley poles). However, by 1900 the B&O had replaced this setup with an under-running, third-rail system. The railroad went back to GE for more locomotives in 1912, 1923, and 1927. Its electrification remained in use until the 1950's when it was replaced by diesel locomotives.
Another early proponent was the New York Central. As historians Brian Solomon and Mike Schafer note in their book, "New York Central Railroad," the NYC had closely watched the B&O's work during planning of a new terminal on Manhattan Island to be served by electrification. Sadly, while these studies were ongoing a serious accident occurred inside the Park Avenue Tunnel on January 8, 1902 when an inbound train missed a stop signal and plowed into a fully loaded New Haven commuter consist. The cause was heavy smoke impairing the engineer's vision and the subsequent outcry banned steam locomotives throughout the city by July 1, 1908. Efforts to electrify were expedited after the accident. The NYC ultimately based its design from the B&O's utilizing a 660-volt DC, "under-running" third-rail system (This was an electrified rail, picked up via a "shoe" equipped on the locomotive, and covered by a wood plank. The latter not only reduced the chance of accidental electrocution but also kept debris or weather-related issues from fouling the system.). The project was launched in 1903 and opened for service on September 20, 1906 between Grand Central Station (later Grand Central Terminal) and High Bridge (7 miles). In the succeeding three decades Central extended the network, including portions of the Harlem Line and Putnam Division, until it boasted around 70 route-miles of electrified territory by 1931.
The densely populated Northeast featured the greatest concentration of electrification throughout the country; in July of 1907 the New York, New Haven & Hartford opened its first segment between Woodland Junction, New York and Stamford, Connecticut. The railroad was the region's preeminent commuter service, boasting a high-speed main line between New York and Boston while serving numerous surrounding communities. Its 11,000-volt AC, 25-cycle, single-phase system was eventually strung from New York to New Haven with appendages reaching Danbury and New Canaan, Connecticut. Alternating-current (AC) was developed, and championed, in the late 19th century by George Westinghouse as a substitute to General Electric's direct current technology. The two became long-time rivals even after signing a patent pool in 1896 granting each the right to sell either type. Since direct current was the established method and relatively easy to implement it took some time for Westinghouse to gain a following for his system. Alternating-current carried several advantages over DC including no substations to maintain sufficient supply, voltage could be carried over long distances without power loss, and availability of more powerful induction motors operating at a constant speed and torque. AC did have one notable drawback, it was relatively complicated although as technology advanced it became better understood (by the 1920's refinements enabled DC traction motors to utilize AC power).
Designations, Types, And Characteristics
Electrics are categorized using a unique system, somewhat similar to how steam locomotives are classified. As an example, take New York Central's original 1-D-1 motors. This odd set of numbers and letters designate powered and unpowered axles.; unpowered are classified using numerals whereas powered axles feature letters. So, in the case of the 1-D-1; the “1” refers to one unpowered axle located on each end of the locomotive and "D" notes four powered axles. Going further, the letter "A" is a single powered axle, "B" two powered axles, "C" equals three powered axles, and so on. While at first this may appear tricky the system is actually quite simple once the basics are grasped. As AC technology gained widespread use some very powerful locomotive types sprang forth such as the PRR's successful GG-1 line, New Haven's EP-5 "Jets," and Virginian's EL-C rectifiers.
Direct current remained preferred by some for its ruggedness and simplicity. The greatest example was Milwaukee Road's famously well-built, 3,000-volt operation strung across Montana, Idaho, and parts of Washington spanning 660 miles. Also, many interurbans carried direct current systems. Despite America's pioneering ways with electrification there was never any uniformity established. As Mr. Solomon's book notes three were three types ultimately employed; direct current, single-phase alternating current, and three-phase alternating current (only Great Northern used this system during electrification of its Cascade Tunnel in Washington State). These were broken down based on power output; low-voltage DC (B&O, New York Central, and most interurban/streetcar systems), moderate-voltage DC (Milwaukee Road), and high-voltage AC (New Haven, Virginian, Pennsylvania, Norfolk & Western, and Great Northern). During the early 20th century a handful of other carriers electrified portions of their main lines either for long-haul service or suburban operations such as the PRR, Lackawanna, Illinois Central, and Reading. Finally, coal-hauler Virginian Railway, a regional pike connecting the ports of Newport News/Norfolk, Virginia with the coal fields of southern West Virginia, energized its main line from Roanoke to Mullens, West Virginia in the mid-1920's utilizing a 11,000-volt AC system with powered supplied by its own plant at Narrows, Virginia.
Known Preserved Locomotives
For purposes of this site the surviving electric locomotives listed here were built during the 1960s and before. Unfortunately, because electrics use an expensive and special power source (overhead wires or third rail) virtually none of the classic models which survive remain in any kind of operational status (one exception is South Shore "800" #803, operational at the Illinois Railway Museum). In any event, thankfully many of the most famous motors have been preserved in some fashion such as Pennsylvania GG1's or Milwaukee Road "Little Joes." This list will be categorized by those railroads that owned electrics and those which survive. One final note, the locomotives listed below are those which served in main line freight service and does not include trolley or interurban cars.

Electrification holds notable advancements in the future of diesel-electric technology. First, Mr. Sprague is credited with developing a electro-pneumatic multiple-unit control system during work on New York Central's first locomotive, 1-D-1 #6000, constructed in 1904. Also known as simply "MU" it enables the engineer to control all of the locomotives in a consist from the lead unit. This system was incorporated into the diesel's development. Second, when GE and Westinghouse battled for supremacy each needed a manufacturer to build their locomotives. The former partnered with the American Locomotive Company to construct DC-equipped units while the latter engaged with Baldwin Locomotive Works in development of AC motive power. These partnerships remained the diesel-electric era and Westinghouse went on to purchase Baldwin in the early 1950's (it exited the market entirely a few years later).
Electrification In America Today
Because of the astronomical implementation costs railroads chose only to employ electrification when significant savings could be achieved, and only over short distances,. Today, energized freight service is all but extinct. However, Amtrak operates significant intercity operations throughout the Northeast while light-rail-transit system and subway operations can be found scattered here and there. The newest types have advanced immensely since private involvement ended during the 1980's like Amtrak's ALP-44 and HHL which boast over 4,000 horsepower via a three-phase system carrying tractive efforts greater than 150,000 pounds. However, all are manufactured outside of America by European firms ASEA, Alstom, and Siemens. Fast, powerful, and efficient motors are a very unique and interesting aspect of our nation’s rail system despite their rarity.
