                            Amendment to Schedule 13D

Item 1.           Security and Issuer

         This Statement  relates to the shares of Common Stock (the "Shares") of
LB Foster Company. The address of Issuer's principal officers is 415 Holiday 
Drive, Pittsburgh, Pennsylvania 15220.

Item 2.           Identity and Background

         This Amendment Statement is filed on behalf of all persons and entities
and participants of Resource Management,  Inc., an entity incorporated under the
laws of the  State of Ohio and  commonly  known as the  Maxus  Investment  Group
(hereinafter  "MIG"),  Richard  A.  Barone,  an  individual   (hereinafter  "Mr.
Barone"),  Gelfand Maxus Asset Management Inc, an entity  incorporated under the
laws of the State of Ohio  (hereinafter  "GMAM") and Maxus  Securities  Corp, an
entity  incorporated  under the laws of the State of Ohio  (hereinafter  "MSC").
The aforementioned person and entities are collectively referred  to  herein  as
the "Filing Persons". The business  address  of  the  aforementioned  person and
entities is 1301 East Ninth Street, 36th Floor, Cleveland, Ohio 44114-1800.

         The Filing Persons each disclaim  membership in a Group as such term is
defined in Section 13(d)(3) of the Securities Exchange Act of 1934 and the Rules
and Regulations  promulgated thereunder.  However,  because of the relationships
between and among the Filing Persons described  herein,  they determined to make
this filing.

         GMAM and MAM are  registered  investment  advisors  having the power to
dispose  of the Shares  owned by the  investment  clients  for which they act as
advisors. MSC is a broker-dealer.  MIG is a financial services corporation which
owns all of the  outstanding  shares  of  GMAM,  MAM and MSC.  Mr.  Barone  is a
director of GMAM; the controlling  shareholder of MIG;  principally  employed as
CEO and President of MIG, MAM and MSC;  Chairman  of  Maxus  Income  Fund, Maxus
Equity  Fund,  Maxus  Laureate  Fund,  Maxus  Ohio  Heartland  Fund,  and  Maxus
Aggressive Value Fund, all of which are registered under the Investment  Company
Act of 1940.  See Amended  Exhibit A attached to this  amended  Schedule 13D for
additional information on executive officers.

Item 3.           Source and Amount of Funds or Other Consideration

         GMAM owns no Shares  directly but GMAM may be deemed to own (within the
meaning of Rule 13(d)(3) of the Securities  Exchange Act of 1934) 392,378 Shares
purchased  by GMAM for the account of its  investment  clients.  GMAM  disclaims
beneficial ownership of such Shares.

Item 4.           Purpose of Transaction

         The Filing Persons acquired Shares to establish investment positions in
the Issuer.  Subject to market and business  conditions and other  factors,  the
Filing Persons may intend to purchase additional Shares. However, depending upon
such factors,  the Filing Persons may also maintain  their present  ownership of
Shares or sell some or all of the Shares. In 1997 and 1998, the  Filing  Persons
sold or changed status of 199,648 shares at prices ranging from $3.33 to $6.50.
 
Item 5.           Interest in Securities of the Issuer

         Set forth below for the Filing Persons, in the aggregate, is the number
of Shares which may be deemed to be  beneficially owned as of June 16, 1998, and
the percentage of the Shares outstanding represented by such ownership (based on
22,027,824 shares outstanding):

(1) These   Shares are owned by  investment  clients of  GMAM  and MAM  who  may
be  deemed  to beneficially own these Shares by reason of their power to dispose
of  such  Shares  under  its  Investment Management Agreement with such clients.
GMAM  disclaims beneficial  ownership  of all such Shares.
(2) MAM disclaims  beneficial  ownership of all such Shares.
(3) Mr. Barone  owns  no  Shares directly but, by virtue of his positions as CEO
and President of  MAM and MIG he may be deemed to beneficially own  the  392,378
Shares.  Mr. Barone disclaims  beneficial  ownership of  all such Shares.

The Shares were traded Over the Counter.

Item 6.           Contracts, Arrangements, Understanding or
                  Relationships with Respect to Securities of the Issuer.

         Except  as set  forth  in  this  Statement,  there  are  no  contracts,
arrangements,  understanding  or  relationships  (legal or otherwise)  among the
Filing Persons or between any of the Filing  Persons and any other person,  with
