Can you list the top facts and stats about Turbojet train?
Summarize this article for a 10 year old
A turbojet train is a train powered by turbojet engines. Like a jet aircraft, but unlike a gas turbine locomotive, the train is propelled by the jet thrust of the engines, rather than by its wheels. Only a handful of jet-powered trains have been built, for experimental research in high-speed rail.
Turbojet engines have been built with the engine incorporated into a railcar combining both propulsion and passenger accommodation rather than as separate locomotives hauling passenger coaches.
As turbojet engines are most efficient at high speeds,[note 1] the experimental research has focused in applications for high-speed passenger services, rather than the heavier trains (with more frequent stops) used for freight services.
