Monday, September 6, 1943, was the Labor Day holiday and the Pennsylvania Railroad company had laid on 16-car trains to accommodate the expected high demand. At 4pm, the passenger count on the premier train, the Congressional Limited was at 541 people on the 16 cars, being hauled by PRR GG1 electric locomotive number 4930, scheduled to travel nonstop from Washington’s Union Station to Pennsylvania Station in New York.
As the train reached Frankford Junction the train derailed in the Kensington neighborhood of Philadelphia, Pennsylvania, killing 79 people and injuring 117 others. As the train passed through the North Philadelphia station, everything seemed to be in order. The train was even coming in a little bit ahead of schedule. It began to slow its speed, but shortly afterward, as it passed a rail yard, workers saw flames coming from a journal box (a hot box) on one of the cars. Jumping into action, they rang the next signal tower at Frankford Junction, but unfortunately, that call came too late. Before the worker who was manning the tower could react, disaster struck as the train passed his signal tower at 6:06 pm traveling at a speed of 56 miles per hour. The journal box on the front of car #7 had seized and an axle snapped, which caught the truck and catapulted it upwards. The car subsequently struck a signal gantry, which peeled off its roof along the line of windows “like a can of sardines.” From there everything fell apart like a house of cards. Car #8 wrapped itself around the gantry upright in a figure U. The next six cars were scattered at odd angles over the tracks, with only the last two cars remaining undamaged. The scene was one of devastation, with the bodies of the 79 dead lying scattered over the tracks.
Because the derailment happened during wartime, there were a number of servicemen onboard who were on leave. The men immediately jumped into action, helping the injured. Workers from the nearby Cramp’s shipyard arrived with acetylene torches to cut open cars to rescue the injured. That is a long process, that took until the following morning. The rescue work was directed by Mayor Bernard Samuel. The gruesome work of removing the dead was not completed until 24 hours after the accident. The Congressional Limited traveled between Washington DC and New York City, normally making one stop in Newark, New Jersey, covering the 236 miles in 3½ hours at speeds up to 80 miles per hour, which seems fast for the time. All the deaths occurred in cars #7 and #8, and 117 other passengers were injured, some seriously. There were survivors, of course, one of whom was Chinese author Lin Yutang.
The inquiry centered on the journal box on car #7 as the cause of the accident. The railroad mechanics who had inspected and lubricated the box earlier that day swore it had been in good order. Normal practice was for signal towermen to watch passing train wheels for signs of problems and for train crew to look back as trains rounded curves. Somehow, the overheated and eventually burning journal box was missed. How that happened was never explained. Did the towermen and train crew simply become lax in their duties, thinking that nothing ever happened on their train, were they possibly over tired that day, or were the just busy with other tasks. These are questions we will never have answers for, unfortunately.
