The Great Central Railway Class 9N, classified A5 by the LNER, was a class of 4-6-2 tank locomotives designed by John G. Robinson for suburban passenger services. They were fitted with superheaters, piston valves and Stephenson valve gear.

Mr. Ivatt’s new single wheeler, No. 266, had already been running sufficiently long to prove its success in first-class express work, and another engine of a similar type was put in hand.

The Great Central Railway (GCR) Class 9N (LNER Class A5) was Robinson's last passenger tank design. They were designed to pull the difficult suburban services out of Marylebone, which they performed admirably for over 30 years.

The GNR Class A1s remained Class A1 and the NER Pacifics were reclassified A2. The LNER also used Pacific tank engines, initially classified A5-7 and were eventually joined by a class A8. However because of their different lineage and operational …

Six men held this post during the existence of the Great Northern Railway. Until 1868 engines were obtained from outside manufacturers, but after this date were increasingly built at the railway's own Doncaster Works, commonly known as the "Plant". Some engines acquired second-hand or from absorbed companies have been omitted from these lists.

The Great Central Railway (GCR) Class 9N (LNER Class A5) was Robinson's last passenger tank design. They were designed to pull the difficult suburban services out of Marylebone, which they performed admirably for over 30 years. The GCR built three batches between 1911 and 1917.

This engine was constructed to prove to the directors of the Great Northern Railway that it was quite practicable to reach Edinburgh from King’s Cross in eight hours by only stopping at Grantham, York, Newcastle and Berwick.

Sep 19, 2015 · GNR 266 was a unique A4-class prototype designed by Henry Ivatt in 1898 and put into production in 1900 as the A5, one of the last Singles to enter service in Britain.

Mar 4, 2020 · In 1910 No. 265 was fitted with Ivatt's patent crank axle and Joy valve gear (the only use of this valve gear by the GNR) (Grove 3A p. 120). They appear to have been happiest on the light competitive expresses which the GNR ran to important places like Bradford, Cromer (via West Runton) and Manchester.
