What is the difference between an LNER A1 and A3?
The change in class designation to A3 reflected the fitting to the same chassis of a higher pressure boiler with a greater superheating surface and a small reduction in cylinder diameter, leading to an increase in locomotive weight. Eventually all of the A1 locomotives were rebuilt, most to A3 specifications, but no.

What’s the difference between Class A1 and Class A3 locomotives?
Locomotives with the boiler rebuild were given the designation of Class A3. These were followed by three more rebuilds in 1928. The cylinder size was kept the same (20in), except for No. 2544 which had lined 18.25in cylinders so that the tractive effort would be similar to the A1s. This allowed comparative trials to be made.
What kind of locomotive was the A3 Gresley Pacific?
The A3 was a modification of the original A1 design, and all of the surviving A1s were eventually rebuilt as A3s. Thompson designated the remaining members of the A1 class awaiting rebuilding as the A10 Class. Almost as soon as Gresley was appointed the CME of the GNR, he started to think about large express passenger locomotives.
Where was the first LNER Class A1 locomotive built?
The year 1925 was the centenary of the Stockton and Darlington Railway, a LNER ancestor, and the first A1 built at Doncaster in that year, no. 2555, was accordingly named Centenary. No. 2579 was named Dick Turpin, but there was no distinguished racehorse of this name; the name refers to the well-known highwayman.
What kind of boiler does an A1 Loco have?
The original boilers fitted to the original A1 locos,were included in the Boiler Diagram No 94, (hence the description Boiler Type 94). These boilers all had round domes. Later, between 1927 and 1950, further boilers were built, both for new locomotives and also as replacements for older ones.
