 Consolidated Rail Corporation
 STATEMENT (a) The Carrier violated the Rules Agreement
 OF
 CLAIM: effective April 15, 1944, as modified Septem
 ber 1, 1949 (particularly, Rule 1=Scope,
 Rule 2-Seniority, 2-d-l-Seniority Rosters and
 others), January 22, 1974 and April 10, 1975
 when Roadway Mechanic Grover Karper used Conrail
 truck to haul materials and supplies to various,
 locations in the Atlantic Region on June 15,
 16, 17, 22, 23, 24, 27 and 28, 1977, and when
 - Lead Mechanic Joseph Deutsch used Conrail truck

 exclusion of Trackman-Truck Driver Moulton Frantz.
 (b) As the result of such violations, Claimant
 Frantz be compensated at the applicable rate
 for eight (8) hours for each of the days claimed.
 FINDINGS:

 On the claim dates, Lead Mechanic Deutsch and Roadway Mechanic Karper, who were assigned to the Easton M & W Equipment Shop, delivered material to outlying locations for use by roadway mechanics to repair track maintenance equipment. In Petitioner's view, track maintenance man should have been assigned to deliver the equipment. Nothing in this record shows that, by any rule

 or established practice, the duties in question belong exclusively to trackmen and that lead and roadway mechanics are barred from performing them. Both parties allege that the past practice on this property supports their respective positions. Neither has presented supporting proof. In this posture of the record, and since the burden of proof rests with Petitioner,. the claim must be denied.
