The Green Hornet Streetcar (named for its speed and color), trolley № 7078, was headed south on State Street, carrying 63 passengers. Suddenly the streetcar switched to the eastbound track to avoid a flooded underpass. "Apparently, the streetcar motorman was not paying attention and went through that switch at total velocity and hit the side of that truck with dire consequences," said Craig Cleve, author of the book The Green Hornet Streetcar Disaster. 

It is unclear whether the streetcar driver or the streetcar itself was at fault, but the Green Hornet did not slow down. As it approached the turn at approximately 30 mph, the streetcar derailed as it hit a Mack truck hauling 8,000 gallons of gasoline.

The gasoline tanker truck, carrying thousands of gallons of gasoline, jackknifed after the collision and blocked State Street 200 feet north of 63rd Street. The truck driver, Mel Wilson, died in the truck's cab, while the streetcar conductor, William C. Lidell, survived.

Thirty-three people died immediately on the streetcar, and one died later of injuries from the crash. Thirty people survived even though the windows and doors wouldn't open. Fifty people, some on the streetcar and others in the surrounding area, were injured. According to the National Safety Council's report, two days after the crash, it was the largest death toll from a motor vehicle collision, surpassing the 29 people killed in a 1940 Texas train-truck collision. Some victims were identified immediately because of personal belongings, whereas others were identified at the Cook County Morgue by friends and relatives following the crash.

It was a grim task to identify bodies as there wasn't much to go on: burned clothes, melted shoes, a ring, bits of toys, remnants of a letter from a young woman planning her wedding. — Dante Mascione, Chicago Tribune

In addition to the lives lost, the flames consumed nearby buildings and parked cars. The fire destroyed seven buildings between the 6239 and 6247 addresses, leaving 120 people homeless. The total property damage was estimated at around $150,000 ($1,502,663.90 today). William C. Liddell, the streetcar conductor, disappeared after the crash but was arrested the day after, charged with leaving the accident scene.

The streetcar was being switched into a "turnaround" because of the flooded conditions of an underpass beneath a viaduct from which this picture was taken.

In 1955, the Chicago Transit Authority claimed it paid a total of $900,000 ($8,713,400 today) to families of the deceased. The accident was highly investigated, drawing conclusions about what could prevent another such catastrophe. Among them was the addition of drainage systems for frequently flooded underpasses so operators would not have to detour. These two yearly physical examinations of motormen and streetcar doors could remain open in case of an emergency to allow for evacuation. However, in 1958 the CTA elected to stop using streetcars entirely. They were replaced by bus routes that still run today.
