The IC3 "Flexliner" DMU trains are the only self-propelled passenger units on the Israel Railways network. These trains are most easily found on the Tel Aviv-Jerusalem line since the Alstom diesel locomotives are unable to climb the steep grades found on that line. Israel Railways has operated the IC3 DMU since 1992, and currently has 48 3-car trainsets. Trainsets can be coupled together to create a 6 car train.
