This BH20AB-class 89’ MTTX flatcar was used for general purpose bulk loading of construction equipment, industrial machinery, or in this case, the 10,000th delivery of a 737, on its way to Renton, WA, for final assembly and eventual delivery to Southwest Airlines. This momentous occasion occurred in 2018. The flatcar features deck mounted purpose-built pedestals and specialized retainment devices that allows the safe loading and transportation of this unique load. Also included is a BNSF 60’ flatcar used as a buffer car.
