97203–97204 (31970)
These two former Class 31 locomotives were acquired by R&DD as test locomotives. The first, no. 97203, was operated by the Railway Technical Centre, based at Derby. It was used to haul various test-trains operated by the centre. However, in 1987, the locomotive was written-off after having sustained fire damage. Therefore, a replacement in the form of 97204 was converted. This later returned to normal traffic, as no. 31970. Both locomotives were painted in RTC's red/cream livery with a black bodyside band. |
