31737, SECR D Class 4-4-0

Built at Ashford in 1901 to Harry Wainwright's design, and the only one of the SECR D class 4-4-0s to survive. The D class was among the most admired of Edwardian British locomotives, as much for Wainwright's elaborate lined livery as for the engineering.

Withdrawn from Guildford in November 1956, it went first to the museum at Clapham and then to York for the opening of the National Railway Museum in 1975, where it is displayed in South Eastern and Chatham Railway colours. It should not be confused with the SECR D1 class, the twenty-one Maunsell rebuilds of 1921 to 1927, none of which survives.

Location and status last confirmed National Railway Museum, York, August 2026. Subject to verification.

Displayed in the great hall of the National Railway Museum in its original South Eastern & Chatham Railway livery.

No owner or livery is recorded here; the source consulted gives the location and status but not those details.
