LNER Class Y11 was a class of three petrol powered 0-4-0 locomotives built by Motor Rail & Tram Car Company Limited under their Simplex brand and introduced in the years 1919–1925. Two were inherited by the London and North Eastern Railway (LNER) at its formation in January 1923, and a third was purchased later.

Many of the Y9 'Scottish Pugs' also ran with wooden trucks as coal tenders but these were classed as tank engines. The 0-4-0 tank was a popular choice for light shunting duties where tight curves were involved, such as docks. Many railway companies used them, though their specialised work meant they were rarely needed in large numbers.

Year 11 is an educational year group in schools in many countries including England and Wales, Northern Ireland, Australia and New Zealand. It is the eleventh or twelfth year of core education. For some Year 11 students it is their final year studying and may include final exams. In the US and Canada, it is referred to as tenth grade.

When they were allocated a class number in the 1940s, it was 'Y11' in the steam locomotive class series. Similarly, the diesel electric shunters were initially allocated 'J45', being reclassified 'DES1' from September 1945.
