So no one submitted this tab, so I figured it out i think. I play it full step 
down or whatever so the tuning is: 

D----------------- | 
A----------------- | 
F----------------- | 
C----------------- | 
G----------------- | 
D----------------- | 

You play the Am's in the verses like this

D-0--0--0--0--0---1--1--1--0--0--0--0- | 
A-1--1--1--1--1---0--0--0--1--1--1--1- | 
F-2--2--2--2--2---2--2--2--2--2--2--2- | 
C-2--2--2--2--2---2--2--2--2--2--2--2- | 
G-0--0--0--0--0---0--0--0--0--0--0--0- |

Intro: Am , Am , F

Am (Whole verse)
You need to get out of this house
I?ll walk you down to town
We?ll go act our age
Kick rocks, waste summer days
Penny candy at the general store
I?d buy us a pop if I had more
Keep walking inland all day
Spitting and cursing each other?s name
F                                                            Am
?Ain?t this what? ain?t this what brothers are supposed to do?? 
F                                         Am
The blood between us, makes it all but true

Am (whole verse)
So we roll on through
Out past the quarries, sandpits too
Swim out among the rocks and cliffs
Ignorant youth keeps us from death
Find our way out to the tracks
The sun, it beats down on our backs
Well, heaven help us if there?s a train
Dodge it like the beaches of Normandy
F                                                            Am
?Ain?t this what? ain?t this what brothers are supposed to do?? 
F                                         Am
The blood between us, makes it all but true


C                                 G
And we saw that smoke rising over trees
       Am                                            F
And I swore, I swore, I swore that train was out for me
C                                                     G
So I held him tight and felt those tracks rumble underneath
Am                                                              F
He swore, he swore if I didn?t let go he would knock me off my feet
                     C
And that?s what he did
                     G
And that's what he did
                    Am 
And that's what he did
                     F
And that's what he did

Then it ends with Am's again.
