The South Eastern and Chatham Railway (SECR) H Class is a class of 0-4-4T steam locomotive originally designed for suburban passenger work, designed by Harry Wainwright in 1904. Most of the sixty-six members of the class were later equipped for push-pull working for use on rural branch lines.
The two constituent railways of the SECR had both relied on 0-4-4T locomotives for London suburban, and semi-fast train services. The South Eastern Railway (SER) Q class was introduced in 1887, and the London Chatham and Dover Railway (LCDR) R class in 1891. Of these, the R was the most successful design, and was continued in production by Harry Wainwright after the amalgamation of the railways in 1899. However, as traffic continued to increase there was a need for a new powerful 0-4-4T design to take over from the SER Q class. Wainwright therefore based his new design on the LCDR A class.
