Getting used to Santa Fe rails, a pair of BN motors lead a fast rolling eastbound through the curves in Camden, MO. The venerable wig wag crossing signal here started clanging well before a train appeared from around the curve toward CA Jct. and shook the pole with its rapid oscillations. More mundane protection was afforded for the third main track with just crossbucks. This is joint territory between BNSF and NS (former Wabash).
