From September 2010, Stagecoach have cancelled their registration for the 11C/20 service, which runs between Lincoln, Welton, Glentham and Waddingham (before running back to Lincoln in service via the A15). PC Coaches have submitted a registration for the W34D, between Waddingham and Lincoln, though exact routing and timetable details are not yet available.
The current 11C/20 route was, in 1974 (20th May timetable), run by Lincolnshire as service 4, a route from Lincoln to New Holland via Brigg, to allow for connection to the Humber ferries. Four journeys ran in each direction, running to RAF Scampton, then to Hackthorn, omitting Welton, and on to Glentham, Waddingham and Brigg. These departed Lincoln at 08:30 (arriving in Brigg at 09:52, and New Holland at 10:50, for the 11:30 ferry), then 11:30, 14:30 and 19:00 – with similar journey times. Returns from New Holland ran at 08:05 (School Days), 09:00 (Not School Days), 11:45, 15:30 (‘Passengers Change Cars’ – at Brigg) and 18:00. There were similar journeys on Saturdays, and 3 journeys provided on Sundays.
By 1982, the Humber Bridge had removed the need for the New Holland ferries, and the 4 was operating between Lincoln and Brigg only*. The first journey towards Lincoln ran as an extension of service 1 (which operated between Welton and Waddington). The service was similar to the present day 11C, starting from Glentham at 07:46, and running via Welton, Scothern and Nettleham. A return was provided at 16:05 (Mon-Fri only) from Lincoln. Which worked back to Lincoln at 17:13 via the same route. Service 4 continued to follow the same route via RAF Scampton and Hackthorn, towards Brigg – with 4 journeys in each direction. The route is, by this stage, shown as having no Sunday service.
The next timetable I possess for the route shows the 11C/20 arrangement from the RoadCar era, dated 15th April 2002. The 20 leaves Lincoln at 07:07, running to Glentham (not serving Waddingham / Bishop Norton), from where it forms the 11C at 07:35, running into Lincoln via Welton and Scothern, to terminate at 08:31. The evening return leaves at 17:20, reaching Glentham for 18:18, with the 20 returning to Lincoln at 18:45. Through services to Brigg have long been discontinued (though the exact date is unknown – any help would be appreciated). The final (and current) Stagecoach timetable sees the 20 leave Lincoln at 06:48, and extended to serve Waddingham and Bishop Norton, before continuing the 11C to the same timetable as shown above.
In addition to the above, Dents Coaches provide once weekly service 9811 between Brigg and Lincoln on Fridays only. This follows a similar route to the old 4, leaving Brigg at 09:20 and returning from Lincoln at 13:45.
* In 2010, Stagecoach still provide a service between Brigg and Barton on Humber (which was included in the New Holland section of the old service 4), numbered 450. The route is worked by Grimsby-Cleethorpes and was inherited from RoadCar. The timetable is available here.
