The highly anticipated new high-speed train from Jerusalem to Tel Aviv via Ben Gurion Airport is now operating. The final destination of the Jerusalem train is Tel Aviv. The new Jerusalem to Tel Aviv train service is officially called King David Line.
I have traveled by train from Ben Gurion Airport to Jerusalem on New Year's Eve of 2023. The ticket price per passenger was about ISL 15. The train station is actually located inside the terminal building and is one of the easiest ways to travel between Ben Gurion airport and Jerusalem.
The ride to Yitzhhak Navon station was about 25 minutes. There we were able to catch a street taxi and head to our apartment in Jerusalem.
The trains leave every half hour, but passengers must account for the ten-minute time to reach the entrance in Jerusalem. The station is inside a large-scale granite station which requires three escalators.
The train journey time between Jerusalem and Tel Aviv is around 31 min and covers a distance of around 54 km. Operated by Israel Railways, the Jerusalem to Tel Aviv train service departs from Yerushalayim/Yits'hak Navon and arrives in Tel Aviv Haganah.
I havent actually used (yet) Jerusalem - Tel Aviv by train line, but the fact of such existence is just amazing.
