BNSF Geometry Train
I caught this BNSF Railway track geometry train leaving Peoria late Tuesday morning. Scenes are at Bridge Junction on the Tazewell & Peoria Railroad (where the train "turned" after arriving town), W. Clarke Street, off Kickapoo Creek Road and Pottstown.
Track geometry trains measure a track's crosslevel (height of rails relative to the other), track gauge (checks for deviation from standard 4-foot 8 and 1/-inches between rails), line (how straight or curvature it should be vs. how it is) and surface (vertical variation relative to both rails).
