The Neverending Line

Location: Kaihin Makuhari, Japan

The line to get out of the ticket barrier.
改札口を出る行列です。

The line to the ticketing counter.
これはチケットカウンターまでの行列です。

And you haven't seen the end yet.
まだまだ列の最後は見えません。

 After you have gotten your ticket, you will still need to line up to pass through the security check.
チケットを買ったとしても、まだこのセキュリティチェックまでの列に並ばないといけません。

While "line" means 線 it also means 行列 .
Another word for "line" is queue.

If someone jump queue (列に割り込む・横入りをする) , you can tell them これは最後尾じゃないぞ!! (this is not the end of the line!)

That basically will show them how angry you are when they jumped queue. Well, who won't especially if you have lined up for that long.
