Sir Vincent Litchfield Raven, KBE was an English railway engineer, and was chief mechanical engineer of the North Eastern Railway from 1910 to 1922.

The North Eastern Railway Class T2, classified as Class Q6 by the LNER, is a class of 0-8-0 steam locomotive designed for heavy freight, especially for hauling long coal trains to various collieries in the North Eastern region of the UK, with a maximum speed of 40 miles per hour. 120 were built at Darlington Works and Armstrong Whitworth between 1913 and 1921 to the design of Vincent Raven, based on the NER Class T and T1. The batch of fifty built by Armstrong Whitworth from 1919 were A-W's first locomotives to be built, after the conversion of their Scotswood works from ordnance to peacetime production.
