The Skegness part of the line inspired the famous poster, designed in 1908 for the GNR.

A couple of express Skegness-Sleaford-Nottingham trains run avoiding Grantham; these also call at Wainfleet, Boston, Heckington and Bingham.

Sleaford can be accessed by a second route, the Peterborough to Lincoln Line; however, this has services which do not run late at night nor on Sundays.

In November 2005, it was reported that the section between Boston and Skegness was unable to take heavier trains[8] although work to enhance the track took place during winter 2009/10.

The line is not electrified and is single track from Sleaford to Heckington and Hubbert's Bridge to Sibsey, with a passing loop at Boston.

This has been delayed by Network Rail putting back the track repairs between Boston and Skegness to 2010.

[citation needed] When part of the line was shared with the East Coast Main Line, there was a common bottleneck on the three miles north of Grantham to the Barkston South junction, which held up valuable slots on a more important route.
