Legend for the trackage in Louisiana, MO

Orange is the Chicago & Alton mainline to Bowling Green, the swing bridge & interlocking tower would have been to the lower-right of this photo. The C&A mainline is tied to the CB&Q mainline (green) by the transfer track (blue). The purple was called the "city track" for use in dropping off freight for Louisiana. Red is the north-south Highway 79, which was a gravel road at the time. Note the railroad changes over the years, C&A > GM&O > IC > GWWR > KCS, CB&Q > BN > BNSF.
