1970 flyover of Peru & LaSalle, Illinois Wednesday August 26, 1970 10:03 am.
Generally following the RR tracks from Peru's west side through past Westclox to along I&M canal.
Just 6 months old, a BN train is waiting just shy of the crossing with the Rock Island RR and it appears the Rock has a West bound train or a long string of cars sitting on it's "north" track from just E of the Rt 351 bridge to past present-day Illinois Cement.
