Press Release


                        ABC Rail Products and NACO, Inc.
                           Announce Merger Agreement
                                        

     Chicago, Illinois, September 17, 1998 -- ABC Rail Products Corporation
(Nasdaq: ABCR) and NACO, Inc., today announced the signing of a definitive
merger of equals agreement to create one of the largest suppliers of
technologically advanced products for the railroad industry.  This agreement
couples two complementary companies who are well-positioned in their respective
segments of the rail supply industry.  ABC is North America's largest
manufacturer of specialty trackwork, the second largest producer of railcar
wheels and distributor of mounted wheel sets, and a rapidly growing supplier of
railway signal system services.  NACO is the leading North American supplier of
high performance freight car suspension systems ("trucks"), a leading supplier
of other types of freight car trucks, locomotive truck frames, freight car
couplers and related products, as well as high integrity steel castings used in
flow control products.  This tax-free, stock-for-stock transaction is expected
to be accounted for as a pooling-of-interests.  For their most recent four
quarters, ABC's and NACO's pro forma combined sales were approximately $637
million and income from operations was $38 million.

     For its fiscal year ended March 29, 1998 ("fiscal 1997"), NACO's sales were
$303.3 million compared to sales of $277.7 million for the prior year.  Income
from operations for the year was $17.3 million compared with $9.8 million for
the prior year.  Net income for the year was $5.5 million compared to $2.5
million for the year ended March 30, 1997.  For the most recent quarter ended
June 28, 1998, NACO's sales, operating income and net income were $84.7 million,
$5.4 million and $2.1 million, respectively, compared with $70.3 million, $3.8
million and $0.9 million, respectively, for the same period during 1997.  NACO's
sales have increased through internal growth and acquisitions at an average
annual rate of 20% during the five-year period ended March 29, 1998 ($303.3
million in fiscal 1997 compared to $145.8 million in fiscal 1993), and its
income from operations has grown to $17.3 million in fiscal 1997 compared to
$3.6 million in fiscal 1993.

                                                                            more

                                                                               2


     The definitive agreement provides that NACO will be merged with a merger
subsidiary of ABC and that the combined parent will be named ABC-NACO Inc.  ABC
stockholders will continue to hold their ABC shares and NACO stockholders will
receive newly issued ABC shares, representing a 50 percent interest in the
combined company on a fully diluted basis.  The merger is expected to produce
substantial improvements in the combined company's operating results through
productivity enhancements, cost savings and revenue growth opportunities.
Management expects the transaction to be accretive to earnings per share in the
first full year of operations after closing, excluding costs related to the
transaction.

     ABC's and NACO's management teams have jointly analyzed the potential for
operating improvements and have preliminarily estimated the annual pre-tax
effect of such improvements at between $20 million and $25 million, the majority
of which can be achieved within 18 months of closing the merger.  The identified
improvements include maximizing the capacity to produce and distribute wheels,
marketing NACO's products through ABC's existing distribution network, and
enhancing manufacturing productivity by employing NACO's process technology in
ABC's manufacturing operations.

     ABC-NACO will be led by an experienced and deep management team.  Donald W.
Grinter, Chairman and CEO of ABC, will serve as Chairman of the Board; Joseph A.
Seher, NACO's Chairman and Chief Executive Officer will serve as Chief Executive
Officer; Vaughn W. Makary, NACO's President and Chief Operating Officer will
serve as President and Chief Operating Officer; and Robert W. Willmschen, Jr.,
ABC's Executive Vice President and Chief Financial Officer will serve as Chief
Financial Officer.  The combined company's Board of Directors will include
Donald W. Grinter and Joseph A. Seher, three independent Board members from
ABC's Board of Directors and three independent Board members from NACO's Board
of Directors.

     Donald W. Grinter said, "This merger of equals benefits customers and
shareholders of both ABC and NACO by creating a stronger and more efficient
combined company.  The fit of our long-range strategies and the synergy from
this combination are expected to result in meaningful annual cost savings,
significant productivity improvements and increased sales opportunities.
Together, ABC and NACO form a potent technological, manufacturing, marketing and
distribution force in the rail supply industry.  The merged company will be able
to provide our customers increased value through innovative design, engineering
and manufacturing.  This will result in high quality, cost competitive product
offerings for our customers."



                                                                            more

     Joseph A. Seher said, "The merger of ABC and NACO represents a major step
forward in our mutual strategy to become the premier supplier of technologically
advanced products for the rail industry.  By combining the significant
technological talents of both companies, we expect this merger to create an
unparalleled capability to better serve our customers.  The blending of ABC and
NACO operations will give the combined company a very strong base to continue
building our respective positions in the rail supply market and to capitalize on
joint opportunities to develop new products and sell existing products.  The
combination of two of the major companies in our industry, and two strong
management teams, will provide the depth needed to take advantage of the growing
opportunities we see within our industry.  Don Grinter and I have known each
other and worked together in international markets for many years, so I know we
share the same values and commitment to product quality and customer service,
which should ease the transition process."

     Consummation of this transaction is subject to customary conditions,
including regulatory approvals and approval of the merger by stockholders of
each company.  This transaction is anticipated to close by late 1998 or early
1999.
