John Henry may have been able to win a race against a steam hammer pounding in rail spikes, but KUHF is a track-laying train that can do far more than that. According to Houston Public Radio, the 30-car KUHF train can remove old rail ties, install brand new concrete ties and rails, and weld the track together using induction heaters. This entire process happens as the train is moving.
The KUHF train can install its own tracks at a rate of up to 16 ties per minute -- that's around 5,000 per day. Amazing!
