From Monday 2 September 2019 changes will be made to this service:

The 0930, 1130, 1330 and 1530 journeys from Brigg and 10:15, 12:15, 14:15 and 16:15 from Barton towards Immingham will all depart 10 minutes earlier, running earlier throughout the day.

The 1535 journey from Brigg will run later at 1550.

The 0940, 1140 and 1340 journeys from Immingham will all depart 5 minutes earlier.

New timetable

Note also that the route within Immingham has also changed.

From South Killingholme the 450 service no longer passes through the industrial part of the town but rather along Pelham Road from the Bluestone inn to terminate at The County inn as before (possibly via Habrough church?) and vice versa.

This is a more practical solution for people from the Barton direction who wish to visit the Civic Centre and Immingham museum.
