Outlook on Natural Gas • Prices subject to significant short-term variability, due to weather • Regional prices more variable than diesel, due to supply constraints • Next two years: continued expansion of production should keep prices low • Longer term, what could increase prices? – More use in electric generation – More use in industry for chemical feedstock and heat – Development of an export market © Oliver Wyman Outlook on Diesel • Prices expected to remain low, given improved fuel efficiency, mediocre economy, increasing use of NG as a fuel • However, some regulatory factors could put upward pressure on prices: – Ultra-low sulfur requirements adding cost to refiners, – Exports to South American markets could increase, as these do not require ultra-low sulfur specs 8 LNG locomotive power development will require long testing periods, standardization, and infrastructure deployment.

We believe that LNG’s greenhouse gas emissions will be lower than diesel fuel & able to meet Tier 4 standards, though there is no data at present to support this.” – Bob Fronczak, AAR AVP for Environmental and Hazmat 19 So…will the industry face a locomotive “crunch” in 2015?
