What is the name of the Andrew Lloyd Webber musical that takes place entirely on roller skates?

This high-octane rock musical brings a child's train set to life, with every single performer portraying a different engine or carriage while racing around the stage on roller skates. The show, with music by Andrew Lloyd Webber, centers on a competition to find the fastest engine in the world. Its unique concept requires the actors to be not only strong singers and dancers but also highly skilled skaters, capable of performing complex choreography at incredible speeds.

The story follows a young, outdated steam engine named Rusty who competes against more modern and powerful rivals, like the arrogant diesel engine Greaseball and the flashy electric engine Electra. He races to prove his own worth and win the heart of a beautiful first-class carriage named Pearl. The musical first opened in London's West End in 1984 and was a massive spectacle, famous for its elaborate set that included ramps and bridges weaving through the audience.

With lyrics by Richard Stilgoe, the show was a technological marvel for its time and became a global sensation. While its runs on Broadway and in the West End were successful, its most enduring production is in Bochum, Germany, where a custom-built theater has housed the show continuously since 1988, making it one of the longest-running musicals in history.
