                                    PART I
 
ITEMS 1 AND 2. BUSINESS AND PROPERTIES
 
  Burlington Northern Santa Fe Corporation ("BNSF") was incorporated in the
State of Delaware on December 16, 1994. On September 22, 1995, the
stockholders of Burlington Northern Inc. ("BNI") and Santa Fe Pacific
Corporation ("SFP") became the stockholders of BNSF pursuant to a business
combination of the two companies. In order to effect the combination, BNSF was
formed to act as the parent holding company of BNI and SFP.
 
  On October 13, 1994, BNI, Burlington Northern Railroad Company ("BNRR"),
SFP, and The Atchison, Topeka and Santa Fe Railway Company ("ATSF") filed a
railroad merger and control application with the Interstate Commerce
Commission ("ICC"). On August 23, 1995, the ICC issued its written decision
approving and authorizing BNI's acquisition of control of SFP and the business
combination by which BNI and SFP became subsidiaries of BNSF, the resulting
common control of BNRR and ATSF by BNSF, the consolidation of BNRR and ATSF by
BNSF, the consolidation of BNRR and ATSF operations, and the merger of BNRR
and ATSF. Pursuant to the ICC's permissive authority, the business combination
was effected on September 22, 1995.
 
  On December 30, 1996, BNI merged with and into SFP. On December 31, 1996,
ATSF merged with and into BNRR, and BNRR changed its name to The Burlington
Northern and Santa Fe Railway Company ("BNSF Railway"). On January 2, 1998,
SFP merged with and into BNSF Railway.
 
  Through March 6, 1998, BNSF also had an equity interest in Santa Fe Pacific
Pipeline Partners, L.P. and its operating subsidiary, which operated a 3,300-
mile refined petroleum products pipeline system in six western and
southwestern states, substantially all of which interest has now been sold.
See "PIPELINE INVESTMENT."
 
  Through its subsidiaries, BNSF is engaged primarily in the rail
transportation business. At December 31, 1997, BNSF and its subsidiaries had
approximately 44,500 employees.
 
                                     RAIL
 
  The rail operations of BNSF Railway, BNSF's principal operating subsidiary,
comprise one of the largest railroad systems in the United States. BNSF
Railway's business and operations are described below.
 
TRACK CONFIGURATION
 
  BNSF Railway operates over a railroad system consisting of, at December 31,
1997, approximately 34,000 route miles of track (excluding, among other
things, second main track), approximately 25,400 miles of which are owned
route miles, including easements, through 28 states and two Canadian
provinces. Approximately 7,800 route miles of BNSF Railway's system consist of
trackage rights which permit BNSF Railway to operate its trains with its crews
over another railroad's tracks.
 
  As of December 31, 1997, the total BNSF Railway system--including first,
second, third and fourth main tracks, yard tracks, and sidings--consisted of
approximately 51,000 operated miles of track, all of which were owned by or
held under easement by BNSF Railway except for approximately 8,600 miles
operated under trackage rights agreements with other parties. At December 31,
1997, approximately 28,000 miles of BNSF Railway's track consisted of 112-
pound per yard or heavier rail, including approximately 18,700 track miles of
131-pound per yard or heavier rail.

Railway had under short-term leases 11,603 containers, 2,157 trailers, and
18,262 chassis, at December 31, 1997. In addition to the owned and leased

years; the average age from date of manufacture or remanufacture of the
freight car fleet at December 31, 1997, was 19.93 years. These averages are

CAPITAL EXPENDITURES AND MAINTENANCE
 
  BNSF Railway capital expenditures for the periods indicated were as follows

(1) Consists primarily of directly financed equipment acquisitions.
 
                                       2

 
  The above table does not include expenditures for equipment financed through
operating leases (principally, locomotives and rolling stock). BNSF expects
1998 capital expenditures for BNSF Railway to be slightly over $2.0 billion.
Approximately $1.1 billion of these expenditures will be for maintaining
BNSF's track, signals, bridges and tunnels, and to overhaul locomotives and
freight cars. The remainder will be spent on terminal and line expansions,
information system projects and an additional 180 locomotives. In addition to
these capital expenditures on new locomotives, BNSF Railway will acquire 200
new locomotives under long-term leases in 1998.
 
  As of December 31, 1997, General Electric Company, the Electro-Motive
Division of General Motors Corporation and Boise Locomotive Corporation
performed locomotive maintenance and overhauls for BNSF Railway under various
maintenance agreements that covered approximately 2,000 locomotives. These
agreements require the work to be done at BNSF Railway's facilities using BNSF
Railway employees.
 
  The majority of maintenance of way expenditures for track have been for rail
and tie refurbishment and track resurfacing. The extent of the BNSF Railway
track maintenance program (1995 represents pro forma BNSF Railway) is depicted
in the following table:

                                                                    31,

- --------
(1) Includes expenditures for both maintenance of existing route system and
    expansion projects. These expenditures are primarily capitalized.
 
  BNSF Railway anticipates that the 1998 track maintenance of way program,
together with expansion projects, will result in the installation of
approximately 1,000 track miles of rail, the replacement of about 3 million
ties, and the resurfacing of approximately 11,000 miles of track.
 
PROPERTY AND FACILITIES
 
  BNSF Railway operates facilities and equipment to maintain its track,
locomotives and freight cars. It also owns or leases other equipment to
support rail operations, such as highway trailers, containers and vehicles.
Support facilities for rail operations include yards and terminals throughout
its rail network, system locomotive shops to perform locomotive servicing and
maintenance, a centralized network operations center for train dispatching and
network operations monitoring and management in Fort Worth, Texas, computers,
telecommunications equipment, signal systems, and other support systems.
Transfer facilities are maintained for rail-to-rail as well as intermodal
transfer of containers, trailers and other freight traffic. These include 39
major intermodal hubs located across the system and nine intermodal hub
centers off-line used in connection with haulage agreements with other
railroads. BNSF Railway's largest intermodal facilities in terms of 1997
volume are:

facilities. Argentine Yard in Kansas City, Kansas, Barstow Yard in Barstow,
California, and Northtown Yard in Minneapolis, Minnesota are BNSF Railway's
largest freight car classification yards.
