D200 heads south along the Midland Mainline at Milton Ernest with the Traintours 1Z26 'Corby Cutler' railtour on 4 May 1987. D200 was the first Class 40 to enter service in the Spring of 1958, the first of 200 locos, which although ridiculously heavy for a loco producing only 2000hp, nevertheless proved to be reliable performers on both passenger and freight. The tour was a fairly straightforward Preston to London St. Pancras run via Toton. D200 was repainted into its original green livery in 1983, albeit with full yellow ends. This assured it celebrity status, and resulted in it outlasting all its classmates by over three years, as it was retaining for special workings such as this.
