The Great Central Railway Class 8H (LNER Class S1) was a class of 0-8-4T steam tank locomotives designed by John G. Robinson for hump shunting at Wath marshalling yard. Four locomotives were built in 1907/1908 for the Great Central Railway. They …

The Robinson Class S1 0-8-4 Tank Locomotives. Robinson designed these powerful 0-8-4 tank locomotives in 1907 for hump shunting the newly opened Wath-on-Dearne marshalling yard in South Yorkshire. Initially, four were built between 1907 and 1908.

The NER Class S1 (LNER Class B14) was a class of 4-6-0 steam locomotives of the North Eastern Railway. It was designed by Wilson Worsdell and five locomotives were built between 1900 and 1901 at Gateshead works. The S1 was similar to the NER Class S but had larger driving wheels and a higher boiler pressure. [1]

The NER Class X (LNER Class T1) was a class of 4-8-0T tank locomotive designed by Wilson Worsdell for the North Eastern Railway. [1] They were intended for use as powerful shunting engines to arrange and move coal wagons for loading into ships. [1]

The North Eastern Railway (NER) Class S1 (LNER B14) was the second of Wilson Worsdell 's 4-6-0 designs. The first of his 4-6-0 designs, the NER Class S (LNER B13), was a disappointment when compared with the contemporary but smaller NER Class R (LNER D20).

Robinson designed these powerful 0-8-4 tank locomotives in 1907 for hump shunting the newly opened Wath-on-Dearne marshalling yard in South Yorkshire. Initially, four were built between 1907 and 1908. Robinson based the S1 on his 8-coupled tender engines (LNER Q4), but had three cylinders for smooth powerful uphill shunting.

Marsden wrote that after the LNER took over the quartet as Class S1, they built two more in 1932 with trailing-bogie boosters as class S1/3. These boosters were designed to operate in either direction; such a requirement was rare. "It appears that the boosters had problems running in reverse", wrote Marsden.
