I could not find specific information online about the high speed train between Jerusalem and Tel Aviv. I found this language on the Israel Railways' own website:
The easiest and
most convenient way to travel between Tel Aviv and Jerusalem is the
new rapid train, which has been operating since 2019. It starts from
Herzliya and enables a very fast ride to Jerusalem from all the main
train stations in Tel Aviv and vice versa: HaHagana, HaShalom,
Savidor Center und Tel Aviv University!
But all the
timetables still show almost an hour to University station in Tel
Aviv So I called the Israel Railways consumer information. I got a
very friendly, English-speaker agent. I asked him about the high
speed line. He said he never heard of it! He said all of his
timetables show at least 50 minutes. He asked me where I heard of it.
I told him 1) it is
included on your own website; and 2) I know a woman who went from Tel
Aviv to Jerusalem in 25 minutes.
He said he couldn’t
help me. This is MORE than bizarre! To say the least. Does anyone
know how to get to Tel Aviv on the high speed train?
