31452 approaches Firsby on 17 September 1988 with the 1D23 13:45 Skegness to Leeds service. This was in the days when there was a proper train service to the East Coast resort during the summer, rather than just a basic DMU service. The train is just about to negotiate the almost 120 degree curve, where the line from Skegness joins the former Louth to Boston line. The line north from here to Louth closed in 1970.
