The Tel Aviv–Jerusalem railway (also higher-speed railway to Jerusalem, Plan A1, and Railway 29) is a railway line connecting the cities of Tel Aviv and Jerusalem in Israel. The line serves as the main rail link between Tel Aviv and Jerusalem, complementing the old Jaffa–Jerusalem railway. As such, the railway is often referred to in Israel as the high-speed railway to Jerusalem to distinguish it from the older, longer and slower line. In spite of that name, the line is not high-speed under the definition used by the International Union of Railways: both its design speed of 200 km/h (125 mph) and its current operation speed of 160 km/h (100 mph) are below the 250 km/h (155 mph) threshold used by the UIC to define high-speed railways, and it is traversed by IR's regular rolling stock instea
