4-6-4 Class W1 LNER "Hush Hush" Profile and Models

4-6-4 Class W1 LNER "Hush Hush"

No.10000. ©Harry Golding

The LNER Class W1 (also know as the “Hush Hush” due to its secrecy) was an experimental steam locomotive fitted with a high pressure water-tube boiler. Nigel Gresley had been impressed by high-pressure steam in marine applications and approached Yarrow shipyard and boilermakers to produce a suitable boiler. The W1 was the only locomotive with a 4-6-4 configuration to ever run on a British railway. Due to poor performance in test runs and following fruitless modifications, the W1 was rebuilt with a conventional boiler and three simple expansion cylinders before being withdrawn in 1959.
