CNR Canadian National Railway Company

CN (TSX: CNR)(NYSE: CNI) today petitioned the United States Court of Appeals for the District of Columbia Circuit for an expedited ruling ordering the Surface Transportation Board (STB) to render a final decision on the transportation merits of CN's proposed acquisition of the principal lines of the Elgin, Joliet & Eastern Railway Company (EJ&E), to allow the transaction to close by the parties' Dec. 31, 2008, deadline.

"Given the substantial, wide-ranging public interest benefits of our planned acquisition of the EJ&E, we cannot permit regulatory delay to imperil this transaction," said CN President and Chief Executive Officer E. Hunter Harrison.

"We are convinced - and many business and community leaders agree - that the transaction will be good for the Chicago region as a whole. It would ease rail congestion, which is critically important to the region's economy and its continued role as one of America's most important transportation hubs. If unaddressed, rail congestion threatens $2 billion of dollars of production and 17,000 jobs in the Chicago region over the next 20 years.

"Second, the transaction would benefit the environment of the overall Chicago region. For every community along the EJ&E line in the suburbs of Chicago that would see increased train traffic as a result of the transaction, nearly double that number along CN lines in inner Chicago would see decreased rail operations. In fact, roughly 60 communities inside the EJ&E arc would benefit from reduced train traffic as a result of the transaction. That would mean a better quality of life for residents of the Chicago region, with less pollution, fewer idling trains and fewer blocked crossings."

Faced with a Dec. 31, 2008, deadline for completing its purchase of the EJ&E, CN last month proposed a reasonable compromise to the STB that would have allowed the agency to rule on the transportation merits of the EJ&E acquisition while completing its environmental review of the transaction. During this environmental review, CN proposed to maintain an "environmental status quo" by which CN would not shift any of its trains to the EJ&E until that review had been completed. But the agency last week denied CN's petition.

"It is truly unfortunate that the STB rejected CN's compromise solution given the impending deadline on our transaction," Harrison said. "The agency's decision - and continuing uncertainty about the timing of the STB's final decision on the transaction - leave us no option but to ask the court to compel a final STB decision on the transportation merits of the acquisition. We need the STB ruling soon so that we will be in a position to close the transaction before year-end."

CN's petition need not preclude full environmental review of the transaction. If it is granted, that will be a choice for the agency. The STB would have options to assure that if CN's petition is granted, the agency can complete its environmental review of the transaction, including its consideration of the comments of all interested parties and its imposition of lawful mitigation before the transaction would be able to have any adverse environmental effects.

"The bottom line is that the benefits to Chicago's rail network and environment from rerouting trains off congested city and inner Chicago lines onto the underused EJ&E are too great to see this transaction derailed," Harrison said. "We cannot allow controversy created in some Chicago suburbs - and the regulatory delay it has created - to jeopardize the transaction.

"CN appreciates the concerns of suburban communities, and it continues to make substantial efforts to address potential adverse impacts of the acquisition. But in the end we do not believe that concerns from a small but vocal minority of residents should take precedence over the broad public interest and the needs of a far greater number of communities that would benefit from the transaction.

"The transaction is not just about CN - it's also about an efficient Chicago rail network, a sound regional economy, and a better quality of life for more than four million Chicago-area residents."

The STB designated the transaction as "minor" in November 2007 because CN's application did not pose anti-competitive issues. By statute, the STB is required to issue a final decision on minor transactions within 180 days of accepting an application for consideration. In its November decision, however, the STB said it would prepare an Environmental Impact Statement (EIS) on the transaction and that its final decision would be extended beyond the 180 days until the completion of the EIS. The agency's Section of Environmental Analysis began its extensive environmental review of this transaction in December 2007.

After 10 months of review, few competition issues have been raised, yet the STB still has not made a final determination as to whether the transaction passes the statutory competition test.

Other, more complicated transactions reviewed by the STB have closed within a time period comparable to what CN seeks here. In the case of the $10-billion Conrail merger in 1997 - a transaction that traversed 24 states and the District of Columbia, 10,500 miles of rail lines and 2,070 grade crossings - the STB finalized its environmental review in 11 months and issued a decision on the transaction two months later. By contrast, CN's $300-million transaction involves small portions of only two states, 158 miles of rail line and a total of 99 grade crossings.

CN-EJ&E BACKGROUNDER

CN's EJ&E transaction is good for Chicago

The transaction would significantly improve the fluidity of rail operations in the Chicago region, resulting in faster transit times and more reliable service for rail customers. It would enhance the competitiveness of businesses in the region that use rail service, while bringing some relief to communities that have more than their share of freight trains today.

The Chicago area is the transportation hub of North America. One-third of U.S. products shipped by rail move to, from, or through the Chicago area each year. Rail traffic in this region touches five million jobs nationwide every year, $782 billion in output and $217 billion in wages. (2005 CREATE Feasibility Study)

But it can take a freight train more than 24 hours to travel the 30 miles from Chicago's north side to its south side (Howard Street on the north and 127th Street on the south). During the same time period, a CN freight train can travel from Chicago to New Orleans (about 900 miles).

If Chicago regional rail capacity and congestion are not addressed, studies suggest that the Chicago area will lose $2 billion in production and 17,000 jobs over the next two decades. (2005 CREATE Feasibility Study)

The transaction has more neighborhood benefits than negative impacts

The transaction would provide reciprocal environmental benefits - for every community along the EJ&E line in the suburbs of Chicago that would see increased train traffic, nearly double that number along CN lines in inner Chicago would experience a traffic decrease. That means roughly one million people would have additional trains in their communities, but more than 2.5 million would have fewer trains. In fact, roughly 60 communities inside the EJ&E arc would benefit from reduced train traffic as a result of the transaction.

CN's EJ&E transaction will advance the objectives of CREATE

Better use of the EJ&E would provide a head start for the Chicago Region Environmental Transportation Efficiency (CREATE) Program. CN is committing $400 million of private-sector investment to create capacity on the Chicago rail network and by removing CN rail operations from downtown Chicago. The government has not provided comprehensive funding for CREATE, however. Without such funding or some other congestion-reducing initiative, increased rail congestion is expected in Chicago and the inner suburbs, with increased delays to motorists and increased train idling in these communities. Without moving trains onto the EJ&E, Chicago will continue to have high levels of rail operations in more densely-populated communities and less efficient rail operations.

CN is committed to addressing the environmental impact of the transaction

CN has already volunteered to provide reasonable mitigation for the significant adverse impact of the transaction, as measured by the sound standards used by the STB in prior cases. CN has committed roughly $40 million for such mitigation, in addition to the $300 million it would spend to acquire the EJ&E and $100 million for integration, new connections and infrastructure improvements to add capacity on the EJ&E line and allow network synergies to be realized over time.

In August, CN reached an agreement with the City of Joliet - a community along the EJ&E line - that resolves the city's outstanding concerns related to quiet zones, operations, and communications arising from the transaction. CN continues to negotiate voluntary mitigation agreements with many other willing communities along the EJ&E, and remains an active participant in the STB's environmental review of the transaction.

CN has undertakings with Amtrak, Metra and Gary/Chicago International Airport on infrastructure access and service matters arising from EJ&E transaction

- CN has pledged to Amtrak and the STB that, after acquiring the EJ&E, it would permit the federal passenger train company to remain on approximately 11 miles of CN's St. Charles Air Line route, following the re-routing of CN trains off that line and onto the EJ&E, until the Grand Crossing or other alternative acceptable to Amtrak is available. This preserves Amtrak's access to Chicago's Union Station and enables Amtrak to continue providing service to and from downstate Illinois cities such as Champaign and Carbondale. CN also agreed to cap Amtrak's costs for maintaining this line at its current levels, indexed only for inflation in future years.

- CN is having continuing discussions with Metra and, upon CN's acquisition of control of the EJ&E lines, has committed to reaching an agreement that would permit Metra's proposed STAR Line commuter service, should it receive government approval and funding, to jointly use enhanced EJ&E rail lines, which is Metra's preferred option. Thus, the EJ&E transaction would not impede the STAR project. Furthermore, moving CN freight trains off its existing lines and onto the EJ&E could make it easier for Metra to expand North Central Service Line service to communities such as Wheeling, Buffalo Grove, Vernon Hills and Mundelein.

- The expansion of Gary/Chicago International Airport (GCIA) can now proceed since the signing in June of a four-party preliminary memorandum of understanding (PMOU) between GCIA, EJ&E, CSX Corporation, and Norfolk Southern Corporation. The PMOU provides a comprehensive framework for relocating the nearby EJ&E line, a long unresolved matter that had been a key concern raised in opposition to the CN/EJ&E transaction. CN assisted EJ&E in the negotiations and is committed to honor the terms of the PMOU upon regulatory approval of the EJ&E acquisition and to carry out the needed line relocation.

CN and U. S. Steel, the indirect owner of the EJ&E, announced on Sept. 26, 2007, an agreement under which CN would acquire most of the EJ&E for $300 million, subject to regulatory approval by the STB. CN has committed an additional $100 million for integration, new connections and infrastructure improvements to add capacity on the EJ&E line and allow network synergies to be realized over time. CN has also committed roughly $40 million to mitigate the impacts of increased train traffic along the EJ&E.
