This dispute concerns work performed between February 19 and March 14, 1991 involving "cutting rail, drilling holes, installing track ties, and dumping ballast" on ballast deck bridges. The organization contends that this work should have been performed by Track Subdepartment employees rather than Bridge & Building Subdepartment employees, arguing that ballast bridges differ significantly from open deck bridges.

LP 3-70-146

The Organization has established that such work is at times performed by Track Subdepartment employees but has failed to provide convincing evidence that this work is reserved exclusively to such employees. In support of this, the Carrier refers to Third Division Award No. 25386, involving the same parties, which states in part:

[The Organization] does not refute, by citation or example, Carrier's contention that spiking and lining rail on a bridge is work that has been performed by both trackmen and bridgemen, as the need .rose.

The distinction which the Organization makes between ballast

bridges and other types of bridges is not encompassed in any cited

rule. _
