As the Allies put their plans into action in 1944 preparing for the eventual D-Day landings, they knew that they needed to break German logistics in Normandy. As part of the process, Gen. Jimmy Doolittle and the 8th Air Force targeted the rail networks that crisscrossed France.
But while the landings would be known as Operation Overlord and the evacuation of the Dunkirk was called Operation Dynamo, the rail bombings were named Operation Chattanooga Choo Choo.

The operation wasn't named after the "The Simpsons" episode. That would be ridiculous, reader who apparently doesn't understand that World War II happened before "The Simpsons."
No, it was named after a popular song of the day. Glenn Miller had recorded the song "Chattanooga Choo Choo" in 1941 and someone on the staff must have liked it. That would be similar to the missile strikes on Syria having been named after a Katy Perry or Taylor Swift song.

Despite the silly name, the operation was a huge success. The air forces wanted to limit German logistics while obscuring the site of the upcoming landings in Operation Overlord. So they dropped bombs all over occupied France but stipulated that two bombs be dropped at Pas de Calais for every one that hit in Normandy.
Adolph Hitler and his cronies were convinced the landings could come at Calais. The bombs ripped through German railways, marshaling yards, wireless radio stations, and other key infrastructure, softening up Normandy for the invasion.
All thanks to Operation Chattanooga Choo Choo.
