Trains will return to a stretch of railway through Hatfield & Stainforth next month after 1.4 million tonnes of spoil obliterated a section of the line.
Services will partially resume on July 8, five months after they were forced to stop by the Hatfield Colliery landlslip.
Network Rail has also released additional details about the scale of the damage.
More than a million tonnes of spoil shifted all four lines up by five metres and across by 15 metres.
Phil Verster, route managing director for Network Rail, said: “This has been one of the most complex recovery operations in recent years.
“In all, around one million cubic metres of material needs to be moved – that includes the slipped material itself and also enabling movements to create storage such as bunds and dams.
“We have to move approximately 60 thousand cubic metres more spoil before the work to reinstate the track can begin in the coming weeks.
“A section of around five hundred metres of all four lines will be replaced, including switches and crossings and the associated signalling and power supplies. Even then there will be more work to complete while trains run past the site.”
The full timetable will resume on July 29.
