D182 (46045) delivered from BR Derby on 27th September 1962, fitted with air brakes in August 1970 and withdrawn in November 1984, after which it spent some time as 97404 as spares for other research locomotives
I first noted this locomotive in 1978-79, when it was a long term Gateshead loco, and had previously travelled behind it in 2016.
