The final phase of a £280million upgrade to the rail line serving Spalding and the Deepings is to go ahead next month.
Work on the stretch of line from Winsover Road, Spalding, to Werrington, near Peterborough, is due to start on October 24 and last until November 3.
It means there will be no train services between Spalding and Peterborough, in either direction, from 9pm on October 23 until 6pm on November 3.
A rail replacement bus service will operate between Spalding and Peterborough during this period.
Justin Page, area director for Network Rail, said: “This is a complex project involving many miles of railway line between Peterborough and Spalding which is used by both passenger and freight trains.
“This vital project will enable more trains to run, helping to meet growing demand for rail services.
“It will also act as an important diversionary route for the East Coast Main Line at times of disruption or engineering work.”
Network Rail is holding three community drop-ins this week when people can find out more about the final phase of the upgrade of the Great Northern Great Eastern line.
The drop-ins take place at Deeping St Nicholas Primary School on Saturday from 10am until 2pm and at Red Lion Quarter, Spalding, on Monday September 29 between 4pm and 8pm.
A third drop-in takes place again at Red Lion Quarter on Tuesday, September 30, between 10am and 2pm.
Visitors to the drop-in can find out about road closures taking place at level crossings in Spalding, Deeping St Nicholas and Deeping St James until October 17 before the main work starts.
This includes London Road, Spalding, where diversions and temporary traffic lights will be in place from 8pm until 8am on Saturday, Saturday and Monday, September 27 to 29, for preparatory work on installing a new automatic barrier system.
