Please answer the given financial question based on the context.
Context: f0b7 positive train control 2013 in response to a legislative mandate to implement ptc , we expect to spend approximately $ 450 million during 2013 on developing and deploying ptc . we currently estimate that ptc , in accordance with implementing rules issued by the federal rail administration ( fra ) , will cost us approximately $ 2 billion by the end of the project . this includes costs for installing the new system along our tracks , upgrading locomotives to work with the new system , and adding digital data communication equipment to integrate the components of the system . f0b7 financial expectations 2013 we are cautious about the economic environment but if industrial production grows approximately 2% ( 2 % ) as projected , volume should exceed 2012 levels . even with no volume growth , we expect earnings to exceed 2012 earnings , generated by real core pricing gains , on-going network improvements and operational productivity initiatives . we also expect that a new bonus depreciation program under federal tax laws will positively impact cash flows in 2013 . results of operations operating revenues millions 2012 2011 2010 % (  % ) change 2012 v 2011 % (  % ) change 2011 v 2010 .

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 four of our six commodity groups increased during 2012 compared to 2011 . revenues from coal and agricultural products declined during the year . our franchise diversity allowed us to take advantage of growth from shale-related markets ( crude oil , frac sand and pipe ) and strong automotive manufacturing , which offset volume declines from coal and agricultural products . arc increased 7% ( 7 % ) , driven by core pricing gains and higher fuel cost recoveries . improved fuel recovery provisions and higher fuel prices , including the lag effect of our programs ( surcharges trail fluctuations in fuel price by approximately two months ) , combined to increase revenues from fuel surcharges . freight revenues for all six commodity groups increased during 2011 compared to 2010 , while volume increased in all commodity groups except intermodal . increased demand in many market sectors , with particularly strong growth in chemicals , industrial products , and automotive shipments for the year , generated the increases . arc increased 12% ( 12 % ) , driven by higher fuel cost recoveries and core pricing gains . fuel cost recoveries include fuel surcharge revenue and the impact of resetting the base fuel price for certain traffic . higher fuel prices , volume growth , and new fuel surcharge provisions in renegotiated contracts all combined to increase revenues from fuel surcharges . our fuel surcharge programs ( excluding index-based contract escalators that contain some provision for fuel ) generated freight revenues of $ 2.6 billion , $ 2.2 billion , and $ 1.2 billion in 2012 , 2011 , and 2010 , respectively . ongoing rising fuel prices and increased fuel surcharge coverage drove the increases . additionally , fuel surcharge revenue is not entirely comparable to prior periods as we continue to convert portions of our non-regulated traffic to mileage-based fuel surcharge programs. .
Question: if freight revenues increase at the same rate as 2012 , what would expected 2013 revenues be , in millions?
