Class 105 54458 & 51298 pass Sleaford North Junction signal box with the 19:34 Sleaford to Lincoln Central service on 14 June 1986 (not Sheffield as shown in the destination blind). It has just traversed the sharply curved single track line seen here coming in from the right. This links the Lincoln to Spalding line, which is basically freight only for a short stretch from here to Sleaford South Junction, with the Nottingham to Skegness line. This DMU only had another three months left in traffic when this picture was taken.
