Day 15: Pennsylvania Railroad GG1

Information from Wikipedia:

The PRR GG1 was a class of electric locomotives built for the Pennsylvania Railroad (PRR), in the northeastern United States. Between 1934 and 1943 General Electric and the PRR's Altoona Works built 139 GG1s.

The GG1 entered service with the PRR in 1935 and later ran on successor railroads Penn Central, Conrail and Amtrak. The last GG1 was retired by New Jersey Transit in 1983. Most have been scrapped, but sixteen are in museums. The GG1 was 79 feet 6 inches (24.23 m) long and weighed 475,000 pounds (215,000 kg). The frame of the locomotive was in two halves joined with a ball joint, allowing the locomotive to negotiate sharper curves. The body rested on the frame and was clad in welded steel plates. The control cabs were near the center of the locomotive on each side of the main oil-cooled transformer and oil-fired train-heating boiler. This arrangement, first used on the PRR's Modified P5 class, provided for greater crew safety in a collision and provided for bi-directional operation of the locomotive. Using Whyte notation for steam locomotives, each frame is a 4-6-0 locomotive, which in the Pennsylvania Railroad classification system is a "G". The GG1 has two such frames back to back, 4-6-0+0-6-4. The related AAR wheel arrangement classification is 2-C+C-2. This means one frame mounted upon a set of two axles unpowered (the "2") and three axles powered (the "C") hinged with the ball and socket to another frame of the same design (the +). The unpowered "2" axles are at either end of the locomotive. The GG1 was equipped with a Leslie A200 horn.

A pantograph on each end of the locomotive body was used to collect the 11,000 V, 25 Hz alternating current (AC) from the overhead catenary wires. In operation, the leading pantograph was usually kept lowered and the trailing one raised to collect current, since if the rear pantograph failed it would not strike the forward pantograph. A transformer between the two cabs stepped-down the 11,000 V to the voltages needed for the traction motors and other equipment. Twelve 385-horsepower (287 kW) GEA-627-A1 traction motors (AC commutator motors, not AC induction motors) drove the GG1's 57-inch (1,448 mm) diameter driving wheels on six axles using a quill drive. The power required was such that double traction motors were used, with two motors driving each axle. The traction motors were six-pole field, 400 volts, 25 Hz rated each at 385 hp (287 kW). The motors were frame-mounted using quill drives to the sprung driving wheels, providing a flexible suspension system across a relatively-long locomotive frame, which allowed full wheel weight to rest on the rail for good traction regardless of track condition. A series-wound commutator motor's speed is increased by increasing the applied voltage to the motor, thus increasing the current through the motor's armature, which is necessary for increasing its torque and thus increasing motor speed. The engineer's cab had a 21-position controller for applying voltage to the motors. Four unpowered leading/trailing wheels were mounted on each end of the locomotive.

In the 1930s, railroad passenger cars were heated with steam from the locomotive. The GG1 had an oil-fired steam generator to feed its train's "steam line."

Beginning in the late 1910s, the PRR received the FF1, but decided that it was too slow for passenger trains; it was relegated to heavy freight service. In the mid-1920s, it received the L5 electric, which had a third-rail power supply at the time. When the Pennsylvania built the O1 and the P5, it chose the P5 over the O1 for its ability and power on the rails. After a grade-crossing accident with the P5, the cab was moved to the center and was designated P5a. PRR still searched for the ultimate electric, since the P5 did not track well at high speeds and was wondering if the P5a could be improved even further. Soon enough, the Pennsylvania was in luck and found two contacts as early as 1932. The mechanical design of the GG1 was based largely on the EP3, which the PRR had borrowed from the New York, New Haven & Hartford Railroad to compare it to the P5a. In 1933, the PRR decided to replace its P5a locomotives; it asked General Electric and Westinghouse to design prototype locomotives with a lighter axle load and more power than the P5a, a top speed of at least 100 miles per hour (160 km/h), a streamlined body design, and a single (central) control cab. Both companies delivered their prototypes to PRR in August 1934. Westinghouse's R1 was essentially "little more than an elongated and more powerful version of the P5a" with an AAR wheel arrangement of 2-D-2. General Electric delivered its GG1. Both locomotives were tested for ten weeks in regular service between New York and Philadelphia and on a test track in Claymont, Delaware. PRR chose the GG1 because the R1's rigid wheelbase prevented it from negotiating sharp curves and some railroad switches. On November 10, 1934, the railroad ordered 57 locomotives: 14 assembled by General Electric in Erie, 18 by the PRR's own Altoona Works, and 20 more in Altoona with electrical components from Westinghouse in East Pittsburgh and chassis from the Baldwin Locomotive Works in Eddystone. An additional 81 locomotives were built at Altoona between 1937 and 1943. On January 28 1935, to mark the completion of electrification of the line from Washington, D.C., to New York City, PRR ran a special train hauled by Pennsylvania Railroad 4800 before it opened the line for revenue service on February 10. It made a round-trip from D.C. to Philadelphia; it completed the return leg in a record 1 hour and 50 minutes. In 1945, a Pennsylvania GG1 hauled the funeral train of President Franklin D. Roosevelt from Washington Union Station to New York Pennsylvania Station. In the mid-1950s, with declining demand for passenger train service, GG1s 4801–4857 were re-geared for a maximum speed of 90 miles per hour (140 km/h) and placed in freight service. They initially retained their train-heating steam generator, and were recalled to passenger service for holiday-season mail trains and 'Passenger Extras' such as those run for the annual Army–Navy football game in Philadelphia. Timetable speed limit for the GG1 was 75-80 mph until October 1967, when some were allowed 100 mph for a couple of years. When Metroliner cars were being overhauled in the late 1970s, GG1s were again allowed 100 mph for a short time when hauling Amfleet cars on trains scheduled to run 226.6 miles from New York to Washington in 3 hours and 20 to 25 minutes. On June 8, 1968, two Penn Central GG1s hauled Robert F. Kennedy's funeral train from New York Penn Station to Washington, D.C. The first designer for the GG1 project was industrial designer Donald Roscoe Dohner, who produced initial scale-styling models, although the completed prototype looked somewhat different. At some point, PRR hired famed industrial designer Raymond Loewy to "enhance the GG1's aesthetics." The final design is retrospectively 'Art Deco' as we know it today. Although it was thought until 2009 that Loewy was solely responsible for the GG1's styling, Dohner is now understood to have contributed as well. (Dohner's GG1 designs influenced the modified P5as, which debuted before the GG1 — not, as was thought, the other way around.) Loewy did claim that he recommended the use of a smooth, welded body instead of the riveted one used in the prototype. Loewy also added five gold pinstripes and a Brunswick green paint scheme. In 1952, the paint scheme was changed to Tuscan red; three years later, the pinstripes were simplified to a single stripe and large red keystones were added. On September 6 1943, the Congressional Limited crashed at Frankford Junction, in the Kensington neighborhood of Philadelphia, Pennsylvania, in the United States. The train was pulled by GG1 4930. The accident was caused by a journal box fire (a hot box) on the front of the seventh of the train's 16 cars. The journal box seized and an axle snapped, catching the underside of the truck and catapulting the car upwards. It struck a signal gantry, which peeled off its roof along the line of windows "like a can of sardines". Car #8 wrapped itself around the gantry upright in a figure U. The next six cars were scattered at odd angles over the tracks, and the last two cars remained undamaged. In total, 79 passengers died, all from cars #7 and #8, and 117 were injured, some seriously. On January 15 1953, train 173, the overnight Federal from Boston, was approaching Washington behind GG1 4876. The train passed a signal 2.1 miles (3.4 km) north of Union Station between 60 and 70 miles per hour (97 and 113 km/h), and the engineer decreased the throttle and started applying the brakes. When the engineer realized that the train was not slowing down, and applying the emergency brake had no effect, he sounded the engine's horn. A signalman, hearing the horn and noting the speed of the 4876, phoned ahead to the station master's office. 4876 negotiated several switches at speeds well over the safe limits and entered the station at around 35 to 40 miles per hour (56 to 64 km/h). The train demolished the bumping post, continued through the station master's office and into the concourse, where it fell through the floor into the station's basement. Thanks to the evacuation of the concourse, no one died, either in the station or aboard the train. A temporary floor was erected over the engine, and the hole it created, for the inauguration of President Dwight D. Eisenhower. 4876 was eventually dismantled, removed from the basement and reassembled with a new frame and superstructure in Altoona. The reconstructed 4876 survives at the B&O Railroad Museum in Baltimore.

The accident was determined to have been caused by a closed "angle cock", a valve on the front and rear of all locomotives and rail cars used in the train's airbrake system, on the rear of the third car in the train. The handle of the angle cock had been improperly placed and had contacted the bottom of the car. Once it was closed, the air brake pipe on all the cars behind the closed valve remained at full pressure, keeping the brakes released on those cars while the brakes on the locomotive and first three cars were applied in emergency. The only major electro-mechanical breakdown of the GG1 was caused by a February 1958 blizzard that swept across the northeastern United States and put nearly half of the GG1s out of commission. Exceptionally fine snow, caused by the extreme low temperatures, passed through the traction motors' air filters and into the electrical components. When the snow melted, it short-circuited the components. On about 40 units, the air intakes were later moved to a position under the pantographs.

In 1968, the PRR, with its 119 surviving GG1s, merged with the New York Central Railroad to form Penn Central. Penn Central went bankrupt in 1970 and its freight operations were later assumed by government-controlled Conrail, which used 68 GG1s in freight service until the end of electric freight traction in 1980.

After its creation in 1971, Amtrak purchased 30 GG1s for $50,000 each and leased another 21, of which 11 were for use on New York and Long Branch commuter trains. Amtrak initially renumbered the purchased GG1s as Nos. 900 to 929; later the railroad added a prefixed "4". This replicated some of the numbers of the leased units, which were renumbered 4930 to 4939, except 4935, which kept its old PRR/PC number.

Amtrak unsuccessfully attempted to replace the GG1s in 1975 with the General Electric E60. An E60 derailed during testing at 102-mile-per-hour (164 km/h), forcing an investigation (the E60 used the same trucks as the P30CH diesel then in service with Amtrak) that delayed acceptance. The hoped-for 120 miles per hour (193 km/h) service speed was never achieved (timetable limit was 90 mph, then 80, then 90).

A replacement was finally found after Amtrak imported and tested two lightweight European locomotives: X995, an Rc4a built by ASEA of Sweden, and X996, a French design. The railroad picked the ASEA design, initially nicknamed the "Swedish swifty" or the "Mighty Mouse" and later often referred to as the "Swedish Meatball". Electro-Motive Diesel, then a part of General Motors, was licensed to build a derivative called the AEM-7. As AEM-7s arrived, Amtrak finally ended GG1 service on April 26, 1980.

The last GG1s in use were some of the 13 assigned to New Jersey Transit (#4872–4884) for its North Jersey Coast Line between New York and South Amboy (the former New York and Long Branch) that ran until October 29, 1983, thus retiring the locomotive after 49 years of service. Fifteen production locomotives and the prototype were preserved in museums. None are operational; their main transformers were removed because of the PCBs in the insulating oil.

During the mid-1930s, many railroads streamlined locomotives and passenger cars to convey a fashionable sense of speed. While the Union Pacific had the M-10000 and the Chicago, Burlington & Quincy Railroad the Zephyr, the PRR had the GG1. The GG1 has "shown up over the years in more advertisements and movie clips than any other locomotive." It was also featured in art calendars provided by PRR, which were used to "promote its reputation in the public eye." PRR-painted GG1s appear in the films Broadway Limited in 1941, The Clock in 1945, Blast of Silence in 1961, the 1962 version of The Manchurian Candidate, and Avalon in 1990. Two GG1s appear in the 1973 film The Seven-Ups—a black Penn Central locomotive and a silver, red and blue Amtrak locomotive. A Penn Central GG1 also appears in another 1973 film The Last Detail. PRR GG1 4821 appears briefly in the 1952 film The Greatest Show on Earth, hauling the Ringling Bros. Barnum & Bailey Circus into Philadelphia's Greenwich Yard, as the movie's director Cecil B. DeMille narrates the scene of its arrival. Near the end of the 1951 film Bright Victory, GG1 #4849 is shown pulling into the station. A GG1 and the Congressional were featured on a postage stamp as part of the United States Postal Service's All Aboard! 20th Century American Trains set in 1999.

The PC games Railroad Tycoon II, Railroad Tycoon 3, Sid Meier's Railroads!, Train Fever, Transport Fever and Transport Fever 2 allow players to purchase and operate GG1 locomotive engines on their train routes. The GG1 is also available with the default Trainz Simulator Games in recent years, and is available as add-ons for Railworks, Train Simulator by Dovetail Games and Microsoft Train Simulator.

Model GG1s have been produced in G, O, S, HO, N and Z scales by Rivarossi, Bachmann, Tyco, Lionel, MTH, USA Trains, Kato, Astor, Fine Art Models, Marklin and other manufacturers.

Yesterday, I made the post going over the backstory of the three P Motors from the New York Central. Now since I made three New York Central posts in a row, I thought I’d take a little break from that and make some Pennsylvania Railroad posts going over the new additional engines to my roster of TTTE OCs from the Pennsylvania Railroad. Now this post will go over the backstory of the first batch of new TTTE OCs of mine from the Pennsylvania Railroad, which are four GG1s, and these four GG1s are…

Glenn - brunswick green 5-stripe #4927

Gracie - tuscan red 5-stripe #4877

Garrison - brunswick green #4919

Gaby - tuscan red #4913

After the Pennsylvania Railroad built and electrified the Northeast Corridor, they needed electric locomotives to pull trains in the newly electrified lines of the Northeast Corridor. So they turned to General Electric for a new locomotive. And in 1934, they produced and brought out 15 GG1s, which were given a striking Art Deco shell. They were successful and the Penney’s Altoona Works made 124 more GG1. That brought the total to 139 GG1s. Glenn, Gracie, Garrison, and Gaby were among the GG1s from the Altoona Works, and they were very eager to help their siblings in pulling passengers across the electrified lines of the Northeast Corridor.

Glenn and Grace often took turns to pull the Broadway Limited when it was under electrified lines, while Torpedo, the streamlined K4 #3768, pulled the Broadway Limited the rest of the way to and from Chicago. When the United States entered World War II following Japan’s surprise attack on Pearl Harbor, every railroad, including the Pennsylvania Railroad, underwent heavier and busier wartime traffic. Glenn, Gracie, Garrison, and Gaby helped their siblings in the wartime traffic, pulling long trains full of troops, sailors, engineers, pilots and gunners to New York City where they get in ships and go to Europe to fight the Nazis. In April 1945, Glenn and Gracie doubleheaded and hauled the funeral train of U.S. President Franklin D. Roosevelt from Washington Union Station to New York Pennsylvania Station.

After World War II ended in September 1945, the railroad traffic cooled down. After GG1 #4876 crashed into Washington Union Station in Washington D.C. on January 15, 1953, Gracie took charge of the Federal Express. And a couple of days later, on January 17th, Gracie, along Glenn, Garrison, Gaby, and their siblings pulled trains full of people wanting to participate in the inauguration of newly-elected President Dwight D. Eisenhower. By the mid-1950s, more and more people began abandoning railroads in favor of highways and airlines, which lead to passenger train service to decline. Glenn, Gracie, Garrison, and Gaby were a little confused but very alienated by these changes. Due to the declining passenger train services, GG1s 4801 - 4857 were re-geared for freight service, much to their annoyance but they reluctantly agreed to take on freight service. Glenn, Gracie, Garrison, and Gaby, and the rest of the GG1s remained as passenger service GG1s.

By 1968, with more and more people and freight moving to highways and airlines, the Pennsylvania Railroad reluctantly merged with its ancient rival: the New York Central System… out of desperation to survive. Glenn, Gracie, Garrison and Gaby, along with a few of their siblings, kept their Pennsylvania Railroad liveries, patterns, paint and lettering while the rest of the GG1s were repainted into Penn Central black and received Penn Central lettering. They all did their best to help the Penn Central, and after New Haven was merged into Penn Central in 1969, the struggle to stay alive only got worse. By 1970, the Penn Central gave in and declared bankruptcy, which marked the end of the golden age of American railroading. This lead to Glenn, Gracie, Garrison and Gaby to blame the public for betraying railroads, though they knew better than to said this out loud.

When Amtrak was formed in 1971, Glenn, Gracie, Garrison, Gaby and most of their siblings went to Amtrak. And Glenn, Gracie, Garrison, and Gaby still kept their Pennsylvania Railroad liveries, patterns, paint, and lettering while their siblings were repainted into Amtrak black or Amtrak red-gray-blue. But by the late 1970s the GG1s were beginning to show their age, so Amtrak looked into replacing them with newer electric locomotives. The thought of being replaced sent chills down the frames of the GG1s, but Glenn, Gracie, Garrison, and Gaby were the only GG1s to be rebuilt which allowed them to last longer in service. As newer General Electric E60s began side-lining the rest of the GG1s, Glenn, Gracie, Garrison, and Gaby said their final goodbyes to their siblings.

By the 1980s, AEM-7 electric locomotives showed up on Amtrak’s roster, and Glenn, Gracie, Garrison, and Gaby became mentors to the new and young AEM-7s. By 1983, Glenn, Gracie, Garrison, and Gaby became the ONLY GG1s remaining in service after the rest of the GG1s were officially retired. Also around this time, Amtrak found and restored a huge number of Pennsylvania Railroad passenger cars, and Glenn, Gracie, Garrison, and Gaby were given these PRR coaches and have always pulled them to this very day. When the Chase Maryland Collision occurred on January 4th, 1987, Glenn and Gracie helped bring rescuers, firemen, rescue equipment, and medical equipment to the crash site by train. The two GG1s were praised for their huge help. However, after the Chase Maryland Collision, Amtrak replaced the Pennsylvania Railroad-style amber signals with color-coded position signals (with the Keystone Corridor keeping the PRR-style amber signals), the four GG1s had a tricky time adjusting to the new signals as they worked with amber signals their whole lives since the early 1930s. By late 1989, they soon got the hang of it. By 1996, the four GG1 participated in the 150th anniversary of the founding of the Pennsylvania Railroad, which was formed in 1846. Even though the Pennsylvania Railroad was no longer around after the Penn Central merger and bankruptcy, the 150th anniversary of the PRR’s founding was still very big and special, especially for rail fans and those who once worked for the Pennsylvania Railroad back in the golden days of American railroading.

And to this very day, Glenn, Gracie, Garrison, and Gaby pull trains of Pennsylvania Railroad passenger cars along the Northeast Corridor, not only bringing passengers to their destinations, but to also keep the memory, legacy and spirit of the Pennsylvania Railroad alive.

And so, that’s the story of the four GG1s. I hope you all enjoyed reading this, and the next post will go over the two PRR J1a steam locomotives, so stay tuned for that.
