Sharon Railway follows the route of Highway 531 between Kfar Saba and Herzliya
Sharon Railway (Hebrew: מסילת השרון, romanized: mesilat ha-šaron) is a double-track railroad in the Sharon plain area of Israel, currently being constructed in the median of Highway 531 as a connection between the Coastal Railway and the Eastern Railway. Out of the total projected length of 12 km, only 5 km have been completed by end of 2017. The project includes widening the section of the Coastal Railway between Tel Aviv University and Herzliya, which is double-track since the late 1980s, to four tracks.
The construction of both the highway and the railway started in the early 2000s, and the first station on the new line, Kfar Saba–Nordau, opened on 13 April 2003. The second station, Hod Hasharon Sokolov, opened on 2 September 2006. Two more new stations, Ra'anana South and Ra'anana West, opened on 3 July 2018. The connection to the Coastal Railway is expected to be completed in 2019, and will reduce travel time between Raanana and Tel Aviv Savidor Center from 40 minutes to 20.
