Thornaby TMD was a railway Traction Maintenance Depot situated in Thornaby, England, and latterly operated by D B Schenker.
Thornaby opened as a steam shed under British Railways in June 1958 with the depot code 51L. It took over the allocations of the 'decrepit establishments' at Newport (depot code 51B) and Middlesbrough (51D)[1]. In June 1959, the depots at Stockton (51E) and Haverton Hill (51G)[1] were closed and the bulk of their locomotives added to Thornaby's allocation. At this time, the depot had the largest allocation of any single depot in the country (Stratford (30A) had a larger allocation, but this was shared with 6 sub-sheds).[2] The depot closed to steam in December 1964. Apart from the ubiquitous Class 08 shunter, early diesel allocations included members of Class 03, Class 04, Class 17, Class 25 (from the first batch built at Darlington), Class 27 and Class 37.[3] It serviced the adjacent Tees Yard. Tornaby is still in active service and has a range of Class 59, Class 66, and Class 47s serving it. Class 37s are rarly seen in or leaving Tornaby TMD, but there are still 3 Class 37 based at thornaby and are still there to this very day, however they are rarely seen as they are in the engine shed to the west of the TMD.
Under TOPS, the depot code was TE.
The logo applied to the sides of Thornaby locomotives was a white Kingfisher.
The buildings were demolished between May and July 2011.[4]
