The proastiakos suburban railway line will link Patras with Kato Achaia, south of the Greek city, in about a year's time, said Apostolos Katsifaras, head of the Region of Western Greece, on Wednesday.

"We set as a top priority this key transport project to boost the economy, tourism growth, the protection of the environment and the quality of life for people, using a friendly means of transport," said Katsifaras after inspecting work on the project so far.

It is the first project to be included in the ESPA program for the new period and is being financed via western Greece's operational program.
