Alright, lets see how many 80's metal nuts we have here (that was your first clue btw). The song also features a guitarist who is VERY respected in the guitar world today(second clue). Who can guess what band and song this quote is from:
"Watch out world! Ready or not! Another freight train comin'!"
Have at it... this quote is probably not going to be found on Google. I just checked to be sure.
$1 says noone gets it, or has even heard it for that matter. If you get the band, song AND the guitarist, Ill paypal you $2.
