The location meant that it provided motive power to the .75 miles (1.21 km) and steep Riverside Branch. Unliked by crews due to the need to pass through three tunnels and the resultant toxic smoke in their cabs, in 1905 it was electrified using 750 VDC technology, with power supplied via both overhead catenary and, within the tunnels, third-rail. Both of the BTH/Brush 640 hp (BR Class ES1) locomotives were based at Heaton, designed as a Bo-Bo with central cab. They worked from the shed until 1967.
Coded 52B in the NE Region (Newcastle District) under British Railways, in 1954 it had an allocation of 95 locomotives, comprising:16x 4-6-2; 17x 2-6-2; 1x 4-4-0; 14x 2-6-0 (9 LNE + 5 LMS-type); 14x 0-6-0; 12x 2-6-2T; 1x 0-6-2T; 18x 0-6-0T; and 2x ES1's.[2]
On 22 March 2022 a TransPennine ExpressClass 802 derailed at Heaton depot and collided with concrete barriers. There were no injuries reported.[3]
After demolition and redevelopment to diesel traction in the 1960s by British Railways, today the depot is operated by Northern Trains, and mostly houses Northern and LNER rolling stock. The depot code is HT.
Heaton is used by the main express operator of the East Coast Main Line to store stock overnight. In 2004–06, this led to a dispute between the RMT and then operator GNER. Legally in the UK, train operators are allowed to discharge 5 imperial gallons (23 L; 6.0 US gal) of sewage per carriage per journey, onto the railtrack. Most Mk3 carriages have only holding tanks, not fully compliant toilet tanks. Further, Heaton then had no toilet clean-out facilities. However, in the 2000s both the RMT and politicians were concerned at the environmental impact of this legacy issue. In 2006 the RMT agreed waste tank and clean out developments at Heaton with GNER, plus new clean out procedures at all other depots, to solve an ongoing dispute over sewage spray.[4]
