Stroudley is best remembered for his 0-4-2 passenger classes. The first of these was a tender engine version of the D1 class, the D2 or "Lyons" class, introduced in 1876 and which proved to be very successful. A larger version for express passenger work, the "Richmond class", was introduced in 1877. However it is the enlarged B1 class ("Gladstone class") express engines of 1882 for which he is best remembered, the last of which survived until 1933. The first member of this class is preserved at the National Railway Museum in York.
