The End
J.O. The Last Man Lyrics

Trains don't run forever
Like trains, all things have a finite lifespan, including relationships and opportunities.

Fire goes out sometime
Just like a fire that eventually runs out of fuel, some things simply come to an end.

Gotta tell you, baby We've come to the end of the line
The singer is informing their lover that their relationship has reached its conclusion.

Pages of yesterday Fill this book of mine
The experiences of the past shape who we are today and fill the pages of our personal history.

Gotta tell you, baby It is the end of the line
The artist is reiterating that their relationship has ended and acknowledging that they must move on.

I can't remember those good old days They are from a different time
The singer recognizes in hindsight that there were better times in the past, but they also acknowledge that things cannot remain the same indefinitely.
