Refrigerated Boxcar CARB Emission Regulations in California

Effective July 17, 2009, the California Resource Board (CARB) will implement the Transportation Refrigeration Units Airborne Toxic Control Measure (TRU ATCM) regulation, affecting BNSF’s refrigerated boxcar fleet operating in the state of California. This regulation is intended to reduce diesel particulate matter emissions from the transport of refrigerated equipment operating in California.

For more information on CARB TRU ATCM, please visit the CARB Web site.

How will this affect my usage of BNSF’s refrigerated fleet?
Currently, the majority of BNSF’s 72-foot refrigerated boxcar fleet will be compliant with CARB TRU ATCM. However, all of BNSF’s 50-foot refrigerated boxcar fleet will no longer be compliant. Refrigerated boxcars that are non-compliant will no longer be able to enter or transit through the state of California, effective July 17.

What are my alternatives?
Although BNSF’s 50-foot refrigerated equipment will not be CARB TRU ATCM-compliant, BNSF perishable customers will have alternatives for transporting refrigerated products on BNSF into California:

What tools can I use to help ensure compliance?
Because customers are responsible for ensuring only compliant cars are loaded for California, BNSF has adjusted our online tools to assist in managing this new process, effective May 1, 2009.

By using BNSF’s Railcar Equipment Request (RER) tool on, customers will be able to identify which cars are CARB compliant as they place orders. Cars will be indicated as:
  • CARB TRU ATCM Compliant 72-foot Refrigerated Boxcars – Used for traffic originating or terminating in California
  • Non-compliant CARB TRU ATCM 72-foot Refrigerated Boxcars – Used for all non-California traffic
  • Non-compliant CARB TRU ATCM 50-foot Refrigerated Boxcars – Used for all non-California traffic
Customers will also be able to see CARB TRU ACTM-compliant railcars as they trace through the My Reports tool on A “Y” indicated in the new CARB-Compliant field in the report indicates compliant railcars, while an “N” indicates non-compliant cars.

Customers participating in BNSF’s Loading Origin Guarantees (LOGS) program will be able to bid on CARB TRU ATCM-compliant 72-foot refrigerated boxcars by identifying how many cars will be moving to or from California during the bidding process. After winning a bid, customers can use the Railcar Equipment Request (RER) tool to order their cars. For more information and LOGS rules, please visit our LOGS Web page.
