Committee 28 – Clearances

Structures Functional Group

This committee is responsible for maintaining current knowledge of clearances required by law or regulation in each of the political entities through which the member roads of the Association of American Railroads (AAR) operate and making this knowledge readily available to members of the AAR. They are also responsible for publication of clearance diagrams defining clearances required by various AAR interchange rules and developing procedures to protect the movement of excessive dimension or overweight loads.

Success Stories

CSXT recently moved a Mitsubishi Power Systems Americas, Inc. Turbine and Generator from the Port of Charleston SC. to Smyrna GA. to a Southern Companies power generation plant. The move was unique account two (2) privately owned schnable / shiftable cars owned by Emmert International and Mammoet Inc. were consisted in the same train. The Turbine weighed 734,000 lbs and measured 16 ft 9 in. wide and the Generator 659,000 lbs and 15 ft 1 in. wide. Altogether there was approximately twenty (20) lateral and vertical shifts required to get this monster shipment home safe . The move required close coordination between the car operators and railroad crew in charge of the train. The Car Operators shown in the last photo are from L to R, Mr. Tom Bell and Ray Wonnek with Mammoet, then Mr. Stig Broman , Chip Kachel and Carl Youman with Emmert.
