Transport Secretary Grant Shapps will visit Fleetwood to announce £21.9m for two railway lines and a New Stations Fund.
The £500m fund was promised in the Tory election manifesto in November.
But Labour called the plan “meaningless”, adding that £500m would reopen just 25 miles of railway.
And the Rail, Maritime and Transport union (RMT) described the funds as a “drop in the ocean”.
Work is not being started on restoring the historic railway lines. Instead the government is giving funding to develop proposals for two lines – £1.5m to the Ashington-Blyth-Tyne line in Northumberland, and £100,000 to the Fleetwood line in Lancashire.
Communities will also be able to apply for some of the remainder of the £500m pot to restore their lines.
What were the Beeching cuts?
Roughly 5,000 miles of track were closed and more than 2,300 stations were axed in the 1960s, mainly in rural areas, following the Beeching report.
The aim was to cut the mounting debts of the nationalised British Rail by removing duplicated routes and closing the least-used branch lines of the railway. This became known as the Beeching cuts.
The plans drew huge opposition from rural local communities, which campaigned and successfully prevented some routes and stations from closing.
What is the government planning to do?
In Tuesday’s visit to the Fleetwood and Poulton-le-Fylde line, which was closed in 1970, Mr Shapps is expected to say work is beginning to “undo the damage of the Beeching cuts” by investing in transport links to help local economies flourish, and ensure that regions “are better connected”.
Mr Shapps told BBC Breakfast the Fleetwood and Ashington lines were “just the start” and added: “We want to see this whole country linked up with railways, or light railways where appropriate.
“One station I visited recently has the reach of 57,000 people. As we start to open up these stations along these Beeching lines and recreate those lines, we have the potential to reach millions of people. That’s what we intend to do.”
What reaction has there been?
Commenting on the proposals, shadow transport secretary Andy McDonald said: “The Conservatives claim to have been reversing Beeching cuts since 2017 despite not reopening an inch of track.
“Investing in the railway is a fantastic policy but this is meaningless without a serious funding commitment of billions of pounds.
“The timing of this announcement is also suspicious and seems designed to distract from the imminent collapse of the Northern Rail franchise.”
Mick Cash, general secretary of the RMT was similarly sceptical about the government’s plans.
“RMT welcomes any investment in our railways but £500m is a drop in the ocean compared to what’s really required to connect our abandoned communities and reverse decades of cuts to infrastructure and maintenance,” he said.
“The first step is to end the chaos, profiteering and fragmentation of privatisation. Anything else is just window dressing and no one will be fooled.”
But Brian Crawford, chairman of the Poulton & Wyre Railway Society, said restoration of the disused railway line to Fleetwood from Poulton-le-Fylde could make the coastal town a “major tourist destination”.
“The line from Euston to Fleetwood opened up in 1840 and was the first railway to connect any coastal resort at that time.
“There are two aims – one of commuters going to work and the other one is to make Fleetwood a major tourist destination. It has a fantastic seafront but without a railway, we don’t seem to get that many visitors,” he told the BBC’s Today Programme.
