The 'Tiny' Electric Engine That Out-Pulled The Big Boy (And Humiliated Steam)

In the 1950s, the "Big Boy" and the "Allegheny" were the undisputed Kings of the Rails. These 600-ton steam monsters were built to pull mountains and seemed unbeatable.

But then, General Electric built a machine that made them look weak.

The GE EL-C didn't look like a hero. It looked like a brick. It was half the weight of a steam giant, silent, and completely unglamorous.

But hidden inside its boring boxy frame was a sci-fi technology called the "Ignitron Rectifier"—a glowing tube of liquid mercury that allowed this tiny engine to convert raw electricity into supernatural grip.

When put to the test in the Blue Ridge Mountains, the "Brick" started heavy coal trains that stalled the biggest steam engines in history, proving once and for all that brute size doesn't equal power.

This is the story of the electric assassin that killed the steam age.
