TOFC Facilities - Smallest "Pig" Facility On The Frisco

On the subject of smallest TOFC facilities, there's a 1976 list of TOFC ramps somewhere on the forum that is eluding me right now. Lamar, MO was listed as a place with a ramp but I haven't ever found any evidence that a ramp actually existed. IF there was actually a ramp here, it would definitely be among the smallest pig facilities.
