Class I railroads, which, unlike their smaller companions do not really
have another name that they are known by (such as Class IIIs known as
shortlines and Class IIs as regionals). Perhaps that is because they
are the industrial leaders and are always at the forefront of the latest technologies and newest locomotives on the market.
Over the years the number major railroads has shrunk due to mergers, and
what remains today are seven very large mega systems; including the
Canadian roads, Canadian Pacific and Canadian National, there is also CSX Transportation, Norfolk Southern Corporation, Union Pacific, BNSF Railway, and Kansas City Southern.

the definition of a major railroad has changed over the years one
thing about the class has always remained the same, it is defined as the
largest operating railroad, in terms of revenue, in the country. I
apologize that much of the “stuff” below can be rather boring as it
includes many facts and details, but for those who have a deep interest
in railroading (or business in general) will likely find it interesting.
As of 2005, the Association of American Railroads (AAR) defined Class
Is of having operating revenues exceeding $319.3 million annually. As reference this number has changed many times over the years, mostly
the result of rising inflation.
For instance, in 1939 a premier U.S. railroad was defined as having operating revenues of at least $1 million annually but this figured changed to $3 million in 1956, $5 million in 1965, $10 million in 1976, $50 million in 1978, $250 million in 1993, and finally the current standard of $319.3 million (please note that not all dollar amount changes have been included here). It’s also hard to believe that over that time period the number of big railroads has shrunk from over 130 in 1939 to only seven today; including Canadian National and Canadian Pacific it is BNSF Railway, CSX Transportation (or CSXT, a division of CSX Corporation and commonly known as just CSX), Kansas City Southern, Norfolk Southern, and Union Pacific. Of these Kansas City Southern and Union Pacific are the only remaining roads whose names have remained unchanged throughout the decades.

Although there are currently only seven operating systems within the United States’ borders, these companies comprise a staggering
93 percent of the industry’s revenues. Similarly Class Is also make up
the majority of overall route miles as well as total freight tonnage
moved. The below table highlights each railroad (including Canadian National
and Canadian Pacific) regarding their 2012 operating revenue. Of note
Kansas City Southern de Mexico is part of the Kansas City Southern
system. It should be noted that this latest graph now shows CSX ahead
of Norfolk Southern in regards to operating revenue. For years this was
not the case. However, after CSX gained a new head man in the way of
Michael Ward in the early 2000s the railroad has been making large
strides in improved service and operating ratios, particularly in just
the last few years.

As you can see from the previous link, the Association of American Railroads' website provides virtually all of the information you may be researching regarding the railroad industry. However, if you are interested in digging deeper into railroad statistics and similar such information, another fine resource is the Bureau of Transportation Statistics' website.
Two of NS's heritage units, original Norfolk Southern #8114 and Monongahela #8025, along with NS SD70ACe #1030 are on the move through Fort Mill, South Carolina with a string of covered hoppers on July 7, 2012.
While the western roads of Union Pacific and BNSF continue to
outpace all other major roads currently in terms of revenues, do not
be surprised with CSX's size and improved efficiencies if it begins to
close this gap somewhat in the coming years (in early 2012 the railroad
announced a massive revenue gain with new customers totaling more than
$230 million). In any event, for railroad enthusiasts and historians
unfortunately the number of large lines in operation likely will not be
growing any time soon, that is unless one of the major shortline owners
would somehow manage to begin unifying their small lines which quite
likely will not happen.

Besides Class Is there are also a number of Class IIs, commonly
referred to as regionals, and Class IIIs, which are known as shortlines
or terminal/switching railroads. While these classes of railroads make
up just a fraction of the overall annual tonnage hauled throughout the
country they make up the greatest number of railroads, totaling well
over 500. Likewise, in many ways, these smaller railroads can be the
most interesting, harkening back to the days of single-car customer
shipping and local freights making their way down a backwoods
branchline. For more information on regionals, please click here. Lastly, for more information on shortlines, please click here.
