Back in the 1800s, the railway was the primary method of moving goods cross country. Millions of people worked on the railway. The Highball cocktail was invented as a quick recipe to entertaining these hard working people.
The drink was in fact named after the signal used when a train was moving through an area in a hurry.
By the 1920s, in cocktail-crazy gin joints around the world, the highball became a classic.
