 (Brotherhood Railway Carmen/Division of TCU PARTIES TO DISPUTE:

STATEMENT OF CLAIM:

 1. That the Kansas City Terminal Railway Company violated Rules 71 and 73 of the current working Agreement when on April 24, 1987 they assigned Mike Rocke and Roy Pennington, who are not Carmen, to take the Cline Truck and. rerail Cars TTPX 82521 and TTPX 81310 flat load of lumber that were derailed at Mill Street Yard.

 2. That because of such violation, the Kansas City Terminal Railway Company be ordered to compensate Carmen N. J. Hayes, who was available to be called to perform the work, four (4) hours at the overtime rate of pay.

 FINDINGS:
The Second Division of the Adjustment Board upon the whole record and all the evidence, finds that:

 The carrier or carriers and the employe or employes involved in this dispute are respectively carrier and employes within the meaning of the Railway Labor Act as approved June 21, 1934.

 This Division of the Adjustment Board has jurisdiction over the dispute involved herein.

As Third Party in Interest, the International Brotherhood of Firemen and Oilers was advised of the pendency of this dispute, but chose not to file a response with the Division.

 A Claim for four (4) hours was filed by the Organization at the Kansas City Terminal on grounds that non-Agreement employees were used to rerail cars. On April 24, 1987, flat loads of lumber TTPX 82521 and 81310 were rerailed at the Carrier's Mill Street Yards by a Sheet Metal Worker and a Laborer. According to the Claim such represented violation of Agreement Rules 71 and 73. The Rules at bar read as follows:

"WRECKING CREWS

Rule 73






In support of its Claim the Organization presents a statement by one Carman working on this property that: "as long as (this Carman) worked for the K.C.T. Ry the rerailing (of) freight equipment had been Carmen's duties."

 In denying the Claim the Carrier states that the rerailing of derailed equipment is not the exclusive purview of Carmen on this property although members of this craft have assisted with this type of work in the past. Correspondence by the Carrier to the Organization under date of February 29, 1988, is pertinent in this respect and is cited here for the record:

 "..(the) Carrier has provided the Organization with factual figures for approximately the last 20 years wherein the mechanical department employees (a department which includes Carmen as well as other shop craft employees) re-railed approximately 20% of derailed equipment on the K.C. Terminal. Almost 80% of the derailments logged were re railed by other than Carmen therefore refuting any claims to exclusivity."

 A review of the full record in this case shows that Carmen have participated in the rerailment of equipment on this property. The same record does not sup port the conclusion, however, according to substantial evidence criteria, that such work was under the exclusive jurisdiction of Carmen. Substantial evidence has been defined, for arbitral purposes, as such "relevant evidence as a reasonable mind might accept as adequate to support a conclusion" (Consol. Ed.
 Co. vs Labor Board 305 U.S. 197, 229).

 Claim denied.
