This one is the sole weekday eastbound service that takes the line through Gainsborough, Central and Brigg. Northern 150276 has a short and curving climb to take it from today’s Sheffield station onto the east-west alignment of the old Great Central route. This service, outward headcode 2H01, return 2H00, is all that Gainsborough Central, Kirton Lindsey and Brigg stations receive. But TPE’s services have to cross the East Coast Main Line on the flat at Doncaster. Ease congestion around Doncaster and open up journey opportunities from Gainsborough and Brigg.
