capital plan 2013 in 2014 , we expect our total capital investments to be approximately $ 3.9 billion , which may be revised if business conditions or the regulatory environment affect our ability to generate sufficient returns on these investments .
while the number of our assets replaced will fluctuate as part of our replacement strategy , for 2014 we expect to use over 60% ( 60 % ) of our capital investments to replace and improve existing capital assets .
among our major investment categories are replacing and improving track infrastructure and upgrading our locomotive , freight car and container fleets , including the acquisition of 200 locomotives .
additionally , we will continue increasing our network and terminal capacity , especially in the southern region , and balancing terminal capacity with more mainline capacity .
construction of a major rail facility at santa teresa , new mexico , will be completed in 2014 and will include a run-through and fueling facility as well as an intermodal ramp .
we also plan to make significant investments in technology improvements , including approximately $ 450 million for ptc .
we expect to fund our 2014 cash capital investments by using some or all of the following : cash generated from operations , proceeds from the sale or lease of various operating and non-operating properties , proceeds from the issuance of long-term debt , and cash on hand .
our annual capital plan is a critical component of our long-term strategic plan , which we expect will enhance the long-term value of the corporation for our shareholders by providing sufficient resources to ( i ) replace and improve our existing track infrastructure to provide safe and fluid operations , ( ii ) increase network efficiency by adding or improving facilities and track , and ( iii ) make investments that meet customer demand and take advantage of opportunities for long-term growth .
financing activities cash used in financing activities increased in 2013 versus 2012 , driven by a $ 744 million increase for the repurchase of shares under our common stock repurchase program and higher dividend payments in 2013 of $ 1.3 billion compared to $ 1.1 billion in 2012 .
we increased our debt levels in 2013 , which partially offset the increase in cash used in financing activities .
cash used in financing activities increased in 2012 versus 2011 .
dividend payments in 2012 increased by $ 309 million , reflecting our higher dividend rate , and common stock repurchases increased by $ 56 million .
our debt levels did not materially change from 2011 after a decline in debt levels from 2010 .
therefore , less cash was used in 2012 for debt activity than in 2011 .
dividends 2013 on february 6 , 2014 , we increased the quarterly dividend to $ 0.91 per share , payable on april 1 , 2014 , to shareholders of record on february 28 , 2014 .
we expect to fund the increase in the quarterly dividend through cash generated from operations and cash on hand at december 31 , 2013 .
credit facilities 2013 on december 31 , 2013 , we had $ 1.8 billion of credit available under our revolving credit facility ( the facility ) , which is designated for general corporate purposes and supports the issuance of commercial paper .
we did not draw on the facility during 2013 .
commitment fees and interest rates payable under the facility are similar to fees and rates available to comparably rated , investment-grade borrowers .
the facility allows for borrowings at floating rates based on london interbank offered rates , plus a spread , depending upon credit ratings for our senior unsecured debt .
the facility matures in 2015 under a four year term and requires the corporation to maintain a debt-to-net-worth coverage ratio as a condition to making a borrowing .
at december 31 , 2013 , and december 31 , 2012 ( and at all times during the year ) , we were in compliance with this covenant .
the definition of debt used for purposes of calculating the debt-to-net-worth coverage ratio includes , among other things , certain credit arrangements , capital leases , guarantees and unfunded and vested pension benefits under title iv of erisa .
at december 31 , 2013 , the debt-to-net-worth coverage ratio allowed us to carry up to $ 42.4 billion of debt ( as defined in the facility ) , and we had $ 9.9 billion of debt ( as defined in the facility ) outstanding at that date .
under our current capital plans , we expect to continue to satisfy the debt-to-net-worth coverage ratio ; however , many factors beyond our reasonable control .
