Expansion of the inside-cylinder tank engine by JG Robinson to a "Pacific" size. See Ahrons (1927) for data The first 21 were built for the Great Central from 1911 to 1917. Richard Marsden says this class was the first on the GCR to have superheaters. Originally fitted with the Schmidt design, the class soon (1915-1917) received Robinson's version. The result is shown in Locobase 2323.

Class A5 (Locobase 2323)

Data from Richard Marsden's LNER Encyclopedia at [] (Jan 2004)

Expansion of the inside-cylinder tank engine by JG Robinson to a "Pacific" size. See Ahrons (1927) for data The first 21 were built for the Great Central; once the LNER was formed in 1923, 10 more were supplied as A5s. Richard Marsden says this class was the first on the GCR to have superheaters. Originally fitted with the Schmidt design, the class later received Robinson's version that had features designed to protect the elements from excessive heat when the regulator was closed. Marsden notes: "They were designed to pull the difficult suburban services out of Marleybone, [duties] which they performed admirably for over 30 years."

(13 more had somewhat smaller boilers to fit the LNER's North Eastern lines' loading gauge; See Locobase 3765) See Tufnell (1986).
