I think these are the lyrics sung by Frankie Laine. They agree with several sound samples I listened to.

Copied from http://www.completealbumlyrics.com/lyric/123834/Frankie+Laine+-+The+3.10+To+Yuma.html:

3.10 TO YUMA
George Duning, Ned Washington

I want to ride again on the 3.10 to Yuma.
That's where I saw my love, the girl with the golden hair.
Not a word between us was spoken.
No, the silence never was broken,
But before she left, her eyes said a sad goodbye.
Sad am I.
Sad am I
To think of the chance that I missed.
I could cry,
To think of the lips left unkissed.

Perhaps she'll ride again on the 3.10 to Yuma,
And I can meet my love and tell her how much I care.
Though I have no reason to go there,
And there's not a soul that I know there,
When the 3.10 to Yuma leaves, if I have the fare,
I'll be there.
I'll be there.
I'll be there.
