Homeowners along the Preston to Blackpool railway line have been warned to expect weeks of disruption.
Overnight piling is taking place as the line is electrified with Network Rail engineers on site.
Foundations for the masts and gantries are being put in place.
Piling is a noisy activity that involves driving steel piles deep into the ground.
Residents living near the railway line have been advised to expect some disruption.
Each piling point is 50 to 60 metres apart and there will also be major vehicle activity during the nights.
The rail work follows ten weekends of initial work on the line ahead of the electrification upgrade.
