Operations and Segmentation

3. Operations and Segmentation

The Railroad, along with its subsidiaries and rail affiliates, is our one reportable operating segment. Although we provide and analyze revenue by commodity group, we treat the financial results of the Railroad as one segment due to the integrated nature of our rail network. The following table provides freight revenue by commodity group:

Millions,
for the Three Months Ended March 31,	2015		2014
Agricultural Products	$	939	$	910
Automotive		516		488
Chemicals		897		893
Coal		915		961
Industrial Products		1,017		1,011
Intermodal		967		1,023
Total freight revenues	$	5,251	$	5,286
Other revenues		363		352
Total operating revenues	$	5,614	$	5,638

Although our revenues are principally derived from customers domiciled in the U.S., the ultimate points of origination or destination for some products transported by us are outside the U.S. Each of our commodity groups includes revenue from shipments to and from Mexico. Included in the above table are revenues from our Mexico business which amounted to $544 million and $540 million, respectively for the three months ended March 31, 2015, and March 31, 2014.
