1000, Midland Compound 4-4-0

A preserved Midland Railway Compound 4-4-0 express passenger locomotive, built at Derby Works in 1902 — the first of the celebrated Midland Compound class designed by S. W. Johnson and developed by subsequent CMEs into the standard LMS 4-4-0 type. Withdrawn from British Railways service in 1951 and preserved as part of the National Collection.

No. 1000 represents a key chapter in British locomotive thermodynamics — the Midland Railway's sustained commitment to compound expansion, where high-pressure steam from the inside cylinder is fed to larger outside low-pressure cylinders for a second expansion cycle, extracting additional work from each pound of steam. Displayed at the National Railway Museum in original Midland Railway crimson lake livery.

Last recorded at the National Railway Museum, York, owned by the National Railway Museum. Operating status: Static display. Current livery: Midland Railway crimson lake.
