E7
I hear the train a coming, its rollin round the bend, 

And I ain't seen the sunshine since i don't know when
A7                                                E7
im stuck in folsom prison and time keeps draggin on.
B7                                           E7
but that train keeps a rollin on to san antone.

I don't have the rest of the words to the song...Just listen to it for them.  
There are someparts im sure arn't correct but its close and should be good enough to get you started  
Riff 2 might be a bit off...Listen to the recording to get it perfect.

One of Cash's best songs right here he was a great man..
