Plan one.

Mike's plan in more detail, I hope I got it right.

Double tracking the Wye bridge will be required, as will widening the area between Northdale and the new Lincoln. Benefits include a much longer mainline. More space between Lincoln and Springbank and Jutland. Long passing tracks on the approaches to Lincoln to hold incoming trains. Lincoln business split up between 2 areas. A longer siding up to the spar tree.
Negatives include a lot of downtime and work. Extra crossing on the Wye bridge. Narrower aisles. Loss of Ortona. The mainline follows itself from Jutland through Lincoln and back to Springbank .
