|Rolling down the BNSF Ft Scott Sub. UP Train AAMSA 30 on its way to San Antonio. This train will run as the AAMKB at times. KB stands for Kirby, TX, and is a yard in San Antonio that this train is symboled for part of the time, but switches back and forth between KB and SA. On the right is I-35 with rush hour traffic headed out of Kansas City. This was shot from the College Boulevard overpass.
