Class 58050 holds a significant place in railway history as the last diesel-electric locomotive built by British Rail Engineering Limited (BREL) and the final locomotive constructed at Doncaster Works. Due to its historical importance, the locomotive was designated for the national collection by the Railway Heritage Committee in 2002.

Originally, 58050 was equipped with SEPEX wheel slip equipment, which was removed before the locomotive entered service in March 1987. This was later incorporated into the Class 60s design.

In May 1987, the locomotive was named Toton Traction Depot. It spent most of its working life hauling MGR wagons from collieries to power stations throughout the Midlands, covering 582 miles while also performing passenger service before being withdrawn on August 5, 2002.

On November 17, 2004, the locomotive was exported to France, where it remained until October 26, 2006. It was then sent to Spain on September 18, 2008, and operated alongside several of its classmates on the Spanish high-speed rail lines in the southern part of the country.

In 2012, nine Class 58 locomotives in Spain were transferred to Transfesa ownership, while DB Cargo retained ownership of three locomotives, including 58050. The Class 58s last worked in Spain in 2016, after which they were placed in storage. 58050, along with three other units, was relocated to a depot in Albacete, Spain.

The locomotive remained at Albacete until 2025. Despite numerous attempts by DB Cargo, the Railway Heritage Committee, and the Class 58 Locomotive Group to return the locomotive to the UK, DB Cargo announced that exporting it back to the UK was not feasible due to the presence of asbestos. Consequently, the safest option was to dispose of the locomotive. As a result, 58050, along with 025, 027, and 041, was disposed of in 2025.

In November 2025, a nameplate from locomotive 58050 was donated to the Doncaster Danum Museum by DB Cargo and unveiled at a commemorative event.
