The railway line Vilnius - Kaisiadoris is a section of the Lithuanian railways.
In 2011–2014, Lengiprotrans developed a project for the reconstruction of a double-track section Vilnius - Kaisiadoris for speeds of 160 km / h. As part of a complex technical project, a contact network was designed on the line.
