Two new sections of railway track are set to be built near Dore and Totley station and further up the line to increase the number of trains running from Sheffield to Hathersage.
Network Rail is inviting members of the public to comment on its plans to build more track at Dore and between Bamford and Hathersage.
The proposals are part of more than £1billion worth of investment in the north of England.
Route managing director for Network Rail Phil Verster said: “The updated plans to improve the railway between Manchester and Sheffield are an important part of a wider programme of investment in the north of England.
“Demand for train travel between the two cities is increasing, with forecasts showing by 2029 demand will grow by 56 per cent in Sheffield and 66 per cent in Manchester.
“These proposals will deliver better journeys on the Hope Valley line, improving capacity, frequency and reliability.”
A Transport and Works Act Order from the Secretary of State will be required to build the new sections of track.
Network Rail is set to submit an application in summer 2015 and,the work will be finished by 2018.
