railway was taken over by SPAP and trains were diverted into the SPAP station. The line was modernised in 2007 and is used for limited passenger service. Pyrgos – Kalo Nero – Kyparissia/Zevgolatio The line runs along the bed of the Alpheus river, east of GR-9/E55, then through Zacharo and into the plain westward with a few forested hills northwest of Kaiafa. It runs for most of its length west of the highway, passing into Zacharo and through Neochori and Tholon. At Kalo Nero, the main line turns east and runs inland, joining Corinth–Argos–Tripoli–Kalamata line at Zevgolatio while a short branch continues south from Kalo Nero down the coast to Kyparissia. Corinth – Argos – Nafplion – Tripoli – Kalamata The line branches off from the Athens–Corinth–Patras line, one km west of Corinth Old Station, with a spur entering the Corinth New Station. The line passes through Argos, where there is a branch line of ten km from Argos to Nafplion. It continues on to Tripoli and Lefktro, where a short branch line connects Megalopoli to the main line. In Zevgolatio, the line joins the line from Pyrgos–Kyparissia and continues on to Kalamata. This line used to continue from the main station of Kalamata to the old station of "Kalamata Limin" (Kalamata Harbour), now used as an open air railway museum, and it came to an end at the Port of Kalamata. Track of this last section from Kalamata main station to the port still exists but is no longer in use. Work is in progress on this line, especially between Tripolis and Kalamata, and details are liable to change. Passenger services on the section between Corinth, Argos, Tripolis, and Nafplion resumed on 1 August 2009. Messene – Kalamata This single-track line is a branch of the Corinth–Argos–Tripoli–Kalamata line and is 4.7 km long. The branch starts at Asprochoma then the track follows the GR-82 road closely on the southern side. The line was opened in 1892 and linked Kalamata with Messene where a station building and a freight yard were built. It was closed in 1976, but the tracks were not removed. The line was rebuilt and reopened in September 2007. From 2013 to 2016, there is an occasional operation, from 20 until 28 September, during the Messene's festival and to the Christmas period until 10 January.
