Lancashire and Yorkshire Railway locomotives

The Lancashire and Yorkshire Railway (L&YR) operated two classes of twenty steam railmotors in total.

The L&YR Class 3 was a class of steam locomotives of the Lancashire and Yorkshire Railway introduced in 1891 with forty being built. George Hughes rebuilt six locomotives with superheaters between 1908 and 1909, they were later designated L&YR Class 4. All passed to the London, Midland and Scottish Railway at the grouping in 1923 but were withdrawn by 1930.

The L&YR Class 24 was a class of short-wheelbase steam locomotives of the Lancashire and Yorkshire Railway (L&YR). It was designed by Aspinall and introduced in 1897 for shunting duties. Twenty locomotives were built, but six were withdrawn between 1917 and 1922.

The L&YR Class 30 (Hughes compound) was a class of steam locomotives of the Lancashire and Yorkshire Railway, designed by George Hughes. The prototype was rebuilt from an Aspinall Class 30 locomotive in 1904. Ten new locomotives were built in 1907. The locomotives passed to the London, Midland and Scottish Railway (LMS) in 1923.

The Lancashire and Yorkshire Railway (L&YR) Class 7 was a class of Atlantic passenger steam locomotives to the design of John Aspinall. Forty were built between 1899 and 1902. They were known as "High-Flyers" as a result of having a high-pitched boiler that was supposed to increase stability at speed. All passed into London, Midland and Scottish Railway (LMS) ownership on the grouping of 1923, becoming the LMS's only Atlantic tender engine class. The LMS gave them the power classification 2P. Withdrawals started in 1926, and all were scrapped by 1934.

The Lancashire and Yorkshire Railway Class 28 was a class of 0-6-0 steam locomotive, designed by George Hughes for the Lancashire and Yorkshire Railway (L&YR). It was a rebuild of Aspinall's Class 27, with the addition of a Belpaire firebox and the extension of the footplate and front sandboxes. It was similar, but had larger cylinders and a superheater. It had 5-foot-1-inch (1.549 m) wheels.

The Lancashire and Yorkshire Railway (L&YR) Class 23 is a class of steam locomotive. Their main use was for shunting and for short-trip freight working.

The Lancashire and Yorkshire Railway (L&YR) Barton Wright 4-4-0 was four-coupled eight-wheeled bogie express engine which entered service in 1880.

The Lancashire and Yorkshire Railway (LY&R) Class 111 were designed by Kitson and Company for William Barton Wright, who had a requirement for a short-distance passenger tank locomotive.

The L&YR 2-10-0 was a prospective design for a class of 2-10-0 steam locomotives on the Lancashire and Yorkshire Railway. Initial designs were made by George Hughes between 1913 and 1914, but none of the class were built. If they had been, these would have been the UK's first 10-coupled locomotives in regular service.
