In a bid to avoid service disruptions every monsoon, the Konkan Railway plans to realign the track on four stretches — Nivsar and Adavali in Sindhudurg district, in Ratnagiri, and at Karwar in Karnataka.
At Nivsar, a low-lying station between two tunnels, the first option is to build a bridge as mudslides and soil erosion damage tracks during the rains.
"We will first study the soil conditions prevailing there and whether we are able to touch hard rock for the bridge to be constructed," said an official.
Only if bridges are not a safe option, would the railway consider an alternative route to escape the four problem areas as the cost would be heavy.
Konkan Railway Managing Director, B Tayal, said: "We will study the probability of new alignment with the help of experts."
Since the rains began this year, the railway had to shut the route for a week.
