Alkaline Trio
Trucks and Trains
Tabbed by Jason the Great (DAWgAWD@HoTMaiL.com)

this is the major verse riff
G|-------------------------------------------------------|
D|---------4-----------4---4/5---------------------------|
A|-2-2-2-2---2---2-2-2---2-------------5-----------0-0-0-|
E|-----------------------------3-3-3-3---3--2-3-3--------|

there are a couple  variations off this, here are two examples
G|-----------------------------------------------------------|
D|---------4-----------4---4/5-------------------------------|
A|-2-2-2-2---2---2-2-2---2-------------5---5/7\--------0-0-0-|
E|-----------------------------3-3-3-3---3------2-3-3--------|
   (this variation is used very often)

G|-----------------------------------------------------------|
D|---------4---4-----------4---4/5---------------------------|
A|-2-2-2-2---2---2-2-2-2-2---2-------------5-----------0-0-0-|
E|---------------------------------3-3-3-3---3--2-3-3--------|
   (this variation is less common but still something keep your ears open for)

also there are cases where both variations are used in the same riff, like so.
G|---------------------------------------------------------------|
D|---------4---4-----------4---4/5-------------------------------|
A|-2-2-2-2---2---2-2-2-2-2---2-------------5---5/7\--------0-0-0-|
E|---------------------------------3-3-3-3---3------2-3-3--------|

when going into the chorus, only play the first half of the riff and then do this

A|---------------------------------|
E|-3-3-3-3-3-3-3-3-5-5-5-5-5-5-5-5-|
