Almost 1,000 people have signed a petition calling for the rail link to be restored between King's Lynn and Hunstanton.
Network Rail has previously said reopening the line, which closed in 1969, would need 'a sound business case'.
The cost of reopening the route, which ran via Wolferton, Dersingham, Snettisham and Heacham, is likely to run into millions.
Georgina Turner, from Witchford, near Ely, started her petition two weeks ago.
She said: 'The track bed still exists from King's Lynn to Hunstanton. The seaside town is increasingly popular throughout the year and the traffic is becoming worse and worse.
'Long tailbacks blight the journey for all making what is a relatively short journey long and slow. A regular train service would benefit the seaside town bringing more visitors, travellers to Hunstanton and the environment as it would promote a huge reduction in vehicle fumes made worse by queuing over many miles.'
With hundreds of new homes being built in the town, the main A149 between Hunstanton and Lynn is set to get even more congested. So far 835 people have signed up online.
Robert Turner said: 'My parents live in Hunstanton and it would make life so much easier getting in and out of Hunstanton, with regular visits to the hospital. Sunday traffic when the sun shines is just a nightmare. Ease the congestion and help the environment.'
I Sesman adds: 'Visit the area by car occasionally but would do so more if there was a train.'
Frank Connoley said: 'Far to much traffic on the road already, with yet more houses on the way.'
The route, which snaked north from Lynn across the coastal marshes, boasted a grand Royal Station at Wolferton, on the Sandringham Estate, fit for the comings and goings of Kings and Queens.
Hunstanton literally grew around the railway as seaside holidays became all the rage in Victorian times. But passenger traffic declined in the 1950s and 60s as cars became commonplace.
Through trains from London were withdrawn and replaced by a diesel shuttle service, in 1959. By the time it closed, in 1969, the line was losing £40,000 a year.
A pub has now been built across the former trackbed where the line enters Hunstanton, whose station was demolished after the line closed.
One suggestion is to replace the former rail line with a light railway.
