58046 was handed over to BR during October 1986. Nearing the end of the Class 58 build programme, it had all of the later modifications incorporated from new. It was one of the unnamed members of the class until 7th July 1991, when it was named “Thoresby Colliery” and outshopped in a gleaming coat of Triple Grey with Coal Sector branding. The naming ceremony took place at the High Marnham Power Station open day, not far from the colliery it was named after.
The sector branding was removed in 1994, and during 1995 it was outshopped in Mainline Freight's Aircraft Blue. In September 1996, it was named “Asfordby Mine” and became the only locomotive to carry the RJB Mining logo on its plates; it also worked the “Worksop Aberdonian” railtour alongside 58002. Unusually, no headboard was present; instead, one cab of each locomotive carried the tour name in vinyl on the front. These vinyls stayed on until withdrawal in September 2000. 58046 was another locomotive that enjoyed a further career in France before being disposed of at Alizay in 2023.
