The Pennsylvania Railroad GG1 stands as one of the most iconic electric locomotives in American railroad history. Built between 1934 and 1943, these streamlined machines represented the pinnacle of electric locomotive technology, combining raw power with elegant Raymond Loewy styling. But beneath that Brunswick green paint and those five gold pinstripes lurked a toxic secret that would haunt railroad workers for decades.
The GG1's development began after a fatal grade crossing accident killed the crew of a P5a locomotive when their apple truck collision demonstrated the deadly vulnerability of cab-forward designs. Pennsylvania Railroad responded by creating a center-cab electric that would protect crews from frontal impacts. They tested two prototypes in 1934, the articulated GG1 against the rigid-frame R1, and the GG1's superior tracking won the contract. The railroad ordered 139 locomotives numbered 4800 through 4938, and these machines would dominate Northeast Corridor operations for nearly half a century.
Each GG1 packed twelve traction motors generating 4,620 horsepower continuous with peaks reaching 10,000 horsepower. They could haul sixteen-car passenger trains at 100 miles per hour or massive freight consists with equal confidence. The locomotives became legendary for their reliability and longevity, with some units accumulating over four million miles during their service lives. Their most famous moment came on January 15, 1953, when GG1 number 4876 crashed through the floor of Washington Union Station after brake failure, plunging into the basement just five days before President Eisenhower's inauguration. Remarkably, nobody died in that spectacular crash, though dozens suffered injuries.
But the GG1's real danger wasn't dramatic crashes. It was something invisible, cumulative, and carcinogenic. Every single GG1 contained transformers cooled with askarel, a dielectric fluid containing polychlorinated biphenyls at concentrations exceeding 45 percent. For 48 years, from 1935 until their retirement in 1983, railroad workers serviced these transformers, breathing PCB vapors, absorbing the chemicals through their skin, and carrying contaminated clothing home to their families. The Pennsylvania Railroad knew about PCB toxicity concerns by the late 1960s when scientific papers documented health problems in industrial workers, but replacing transformers in 139 locomotives would have cost millions that bankrupt Penn Central couldn't afford.
In 2013, the International Agency for Research on Cancer classified PCBs as Group 1 carcinogens, carcinogenic to humans, with sufficient evidence linking exposure to malignant melanoma. Studies also documented increased risks for liver cancer, gastrointestinal cancers, and non-Hodgkin lymphoma. Beyond cancer, PCB exposure caused chloracne, liver damage, reproductive problems, thyroid dysfunction, and neurological deficits. The chemicals are fat-soluble, bioaccumulative, and essentially permanent in the environment.
The United States banned PCB production in 1977, but the GG1 fleet received grandfather exemptions and continued operating until October 29, 1983, when New Jersey Transit ran the final farewell trips. Frame cracks and aging infrastructure finally ended their reign, but the PCB contamination sealed their fate. Upon retirement, every GG1 had its main transformer physically removed and destroyed at hazardous waste facilities. The 16 surviving museum locomotives remain powerless shells, their transformers gone forever, beautiful monuments to an era when nobody understood the long-term cost of progress.
