2011 , effectively handling the 3% ( 3 % ) increase in carloads . maintenance activities and weather disruptions , combined with higher volume levels , led to a 4% ( 4 % ) decrease in average train speed in 2010 compared to a record set in 2009 . average terminal dwell time 2013 average terminal dwell time is the average time that a rail car spends at our terminals . lower average terminal dwell time improves asset utilization and service . average terminal dwell time increased 3% ( 3 % ) in 2011 compared to 2010 . additional volume , weather challenges , track replacement programs , and a shift of traffic mix to more manifest shipments , which require additional terminal processing , all contributed to the increase . average terminal dwell time increased 2% ( 2 % ) in 2010 compared to 2009 , driven in part by our network plan to increase the length of numerous trains to improve overall efficiency , which resulted in higher terminal dwell time for some cars . average rail car inventory 2013 average rail car inventory is the daily average number of rail cars on our lines , including rail cars in storage . lower average rail car inventory reduces congestion in our yards and sidings , which increases train speed , reduces average terminal dwell time , and improves rail car utilization . average rail car inventory decreased slightly in 2011 compared to 2010 , as we continued to adjust the size of our freight car fleet . average rail car inventory decreased 3% ( 3 % ) in 2010 compared to 2009 , while we handled a 13% ( 13 % ) increase in carloads during the period compared to 2009 . we maintained more freight cars off-line and retired a number of old freight cars , which drove the decrease . gross and revenue ton-miles 2013 gross ton-miles are calculated by multiplying the weight of loaded and empty freight cars by the number of miles hauled . revenue ton-miles are calculated by multiplying the weight of freight by the number of tariff miles . gross and revenue-ton-miles increased 5% ( 5 % ) in 2011 compared to 2010 , driven by a 3% ( 3 % ) increase in carloads and mix changes to heavier commodity groups , notably a 5% ( 5 % ) increase in energy shipments . gross and revenue-ton-miles increased 10% ( 10 % ) and 9% ( 9 % ) , respectively , in 2010 compared to 2009 due to a 13% ( 13 % ) increase in carloads . commodity mix changes ( notably automotive shipments ) drove the variance in year-over-year growth between gross ton-miles , revenue ton-miles and carloads . operating ratio 2013 operating ratio is our operating expenses reflected as a percentage of operating revenue . our operating ratio increased 0.1 points to 70.7% ( 70.7 % ) in 2011 versus 2010 . higher fuel prices , inflation and weather related costs , partially offset by core pricing gains and productivity initiatives , drove the increase . our operating ratio improved 5.5 points to 70.6% ( 70.6 % ) in 2010 and 1.3 points to 76.1% ( 76.1 % ) in 2009 . efficiently leveraging volume increases , core pricing gains , and productivity initiatives drove the improvement in 2010 and more than offset the impact of higher fuel prices during the year . employees 2013 employee levels were up 5% ( 5 % ) in 2011 versus 2010 , driven by a 3% ( 3 % ) increase in volume levels , a higher number of trainmen , engineers , and yard employees receiving training during the year , and increased work on capital projects . employee levels were down 1% ( 1 % ) in 2010 compared to 2009 despite a 13% ( 13 % ) increase in volume levels . we leveraged the additional volumes through network efficiencies and other productivity initiatives . in addition , we successfully managed the growth of our full- time-equivalent train and engine force levels at a rate less than half of our carload growth in 2010 . all other operating functions and support organizations reduced their full-time-equivalent force levels , benefiting from continued productivity initiatives . customer satisfaction index 2013 our customer satisfaction survey asks customers to rate how satisfied they are with our performance over the last 12 months on a variety of attributes . a higher score indicates higher customer satisfaction . we believe that improvement in survey results in 2011 generally reflects customer recognition of our service quality supported by our capital investment program . return on average common shareholders 2019 equity millions , except percentages 2011 2010 2009 .
