31413 & 31429 round the curve between Nuneaton Abbey Junction and Nuneaton North Junction on 3 October 1987. They are working the 1E66 08:20 Birmingham New Street to Great Yarmouth service. This section of line links the Birmingham to Leicester route with the West Coast Mainline. The direct line crossing the West Coast route via a flyover can be seen in the background, with Abbey Junction signal box just visible near the bridge. Note how the 25kV wires extend for a short distance round the curve, but only on the westbound line.
