On a recent vacation trip from St Charles MO to Hannibal MO drove along the BNSF interesting to seeing all the signals built up on pillars. Rail traffic was not that bad seen a ballast train, rail train coal train and what appeard to be a way freight at Hannibal. What traffic moves on this line and where does it originate, Also we were stopped by the sperry rail car on the crossing of hwy 79 and the KCS. Brought the memory of the "doodle bug" trip that was in the trains magizine years back.One other question how far NS travel on the BNSF at Hannibal?
