we generate freight revenues by transporting freight or other materials from our six commodity groups .
freight revenues vary with volume ( carloads ) and average revenue per car ( arc ) .
changes in price , traffic mix and fuel surcharges drive arc .
we provide some of our customers with contractual incentives for meeting or exceeding specified cumulative volumes or shipping to and from specific locations , which we record as reductions to freight revenues based on the actual or projected future shipments .
we recognize freight revenues as shipments move from origin to destination .
we allocate freight revenues between reporting periods based on the relative transit time in each reporting period and recognize expenses as we incur them .
other revenues include revenues earned by our subsidiaries , revenues from our commuter rail operations , and accessorial revenues , which we earn when customers retain equipment owned or controlled by us or when we perform additional services such as switching or storage .
we recognize other revenues as we perform services or meet contractual obligations .
freight revenues from all six commodity groups increased during 2014 compared to 2013 driven by 7% ( 7 % ) volume growth and core pricing gains of 2.5% ( 2.5 % ) .
volume growth from grain , frac sand , rock , and intermodal ( domestic and international ) shipments offset declines in crude oil .
freight revenues from five of our six commodity groups increased during 2013 compared to 2012 .
revenue from agricultural products was down slightly compared to 2012 .
arc increased 5% ( 5 % ) , driven by core pricing gains , shifts in business mix and an automotive logistics management arrangement .
volume essentially was flat year over year as growth in automotive , frac sand , crude oil and domestic intermodal offset declines in coal , international intermodal and grain shipments .
our fuel surcharge programs generated freight revenues of $ 2.8 billion , $ 2.6 billion , and $ 2.6 billion in 2014 , 2013 , and 2012 , respectively .
fuel surcharge in 2014 increased 6% ( 6 % ) driven by our 7% ( 7 % ) carloadings increase .
fuel surcharge in 2013 essentially was flat versus 2012 as lower fuel price offset improved fuel recovery provisions and the lag effect of our programs ( surcharges trail fluctuations in fuel price by approximately two months ) .
in 2014 , other revenue increased from 2013 due to higher revenues at our subsidiaries , primarily those that broker intermodal and automotive services , accessorial revenue driven by increased volume and per diem revenue for container usage ( previously included in automotive freight revenue ) .
in 2013 , other revenue increased from 2012 due primarily to miscellaneous contract revenue and higher revenues at our subsidiaries that broker intermodal and automotive services. .

Question: Analyse this data from a financial earnings document. if the fuel surcharge grows by the same rate as in 2014what would expected 2015 revenues be in billions?
