How Fast Is Steam Locomotive?

The fastest steam locomotive ever — Mallard — set the steam record at 203 km/h in 1938. The record still stands 87 years later. Steam was supplanted by diesel and electric, not because they were faster, but because they were cheaper.

The steam locomotive speed record is 203 km/h — set in 1938 by Mallard, and still unbroken nearly a century later.

• Faster than the autobahn cruise
• Steam record from 1938 still unbroken
