Found these two BN Covered Hoppers yesterday in Columbia, SC. The one with the large logo has some graffiti on it, but I thought it was worth capturing.
When I took these picture I was thinking of that -- these are a common sight in your region. I also took another of a clean round-and-brown BNSF covered hopper, recalling that some of y'all call unit trains of them "earthworms"! These cars too are a special sight for me.
Ha ha. Yes. "Earthworms." But usually there are at least a few of the non-brown thrown in, to spoil the effect.
