In 1984, 50007 "Hercules" was repainted into lined Brunswick green livery and renamed "Sir Edward Elgar", to commemorate the 150th anniversary of the Great Western Railway (GWR). Four Class 47 locomotives were similarly treated, and a Class 117 diesel multiple unit (DMU) was repainted in chocolate and cream livery. As a result, 50007 quickly became a favourite with rail enthusiasts. Another locomotive repainted in a special livery was 50019 "Ramillies", which was repainted in a variation of BR Blue by staff at Plymouth Laira depot.
