North American freight operator BNSF is to spend $6 billion expanding and renewing its network in 2015.
It is the third successive year that BNSF has announced record levels of capital investment.
In the past 15 years, BNSF has invested more than $50 billion in infrastructure improvements and new rolling stock.
The majority of the funding, $2.9 billion, will go towards renewal and maintenance work. A further $1.5 billion will support expansion projects.
BNSF has also said it plans to procure 330 new locomotives to expand its fleet and replace some life-expired units.
Carl Ice, BNSF president and chief executive officer, said: “We have made great progress in expanding the segments of our railroad that have been most constrained by rapidly increasing demand.
“Once these new capital programs are completed, we expect to further restore the capacity flexibility we have historically enjoyed to manage the periodic demand surges that come from a dynamic and fast-paced economic environment.”
