Bachmann 35-778 OO Gauge Class 69 69003 'The Railway Observer' GBRf

The Class 69 Diesel Locomotive was conceived by rail freight operator GB Railfreight (GBRf) to meet their growing locomotive needs. With a requirement for locomotives similar in performance to their fleet of Class 66s, but being unable to purchase new Class 66s, GBRf turned to redundant Class 56s which could be converted into new locos with similar capabilities. As part of the conversion new equipment and systems were installed, including EMD 710 diesel engines, the same as those used in Class 66s. The pool of Class 56s to be converted included examples built at BREL Crewe, BREL Doncaster and Electroputere in Romania, with the conversion work undertaken in Stoke-On-Trent by the American company Progress Rail.

GBRf formally announced the project in Spring 2019 and the first locomotive, No. 69001, commenced running trials at the Severn Valley Railway in February 2021. The type received approval by the Office of Rail and Road in May 2021, allowing the new locomotives to be pressed into service.

The initial order was for ten locomotives with an option for a further six, and by the start of 2024, the first ten locos - Nos. 69001-69010 - had entered service. Each locomotive has been painted by Arlington Fleet Services in Eastleigh and the liveries applied to the Class 69s range from GBRf#s standard orange and blue scheme, and variations on it, to retro-BR liveries including BR Blue, BR Large Logo Blue, BR Green and RTC Red & Blue. Several of the Class are named including the first locomotive, No. 69001, which entered traffic in GBRf orange and blue adorned with UK and US flags and named 'Mayflower', symbolising the American input into the rebuilding of this British-designed locomotive.
