STATEMENT OF CLAIM:



FINDINGS:

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

The carrier or carriers and the employee or employees involved in this dispute are respectively carrier and employee within the meaning of the Railway Labor Act, as approved June 21, 1934.
Form 1 Award No. 39508
Page 2 Docket No. SG-38732


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






On January 20, 2004, the Carrier designated two supervisory employees to install shunt wires on the tracks inside the absolute signals on the "OS" track circuit located at the south end of Sheffield, Iowa, MP 174.3 on the Mason City Subdivision, causing the effected signals to display red indications for the purpose of an efficiency test of a train crew. Thus, the central issue in this case is whether the installation of temporary shunt wires in connection with such efficiency tests is reserved to Signalmen by the Scope Rule of the Agreement. For its part, the Carrier denied the instant claim, asserting that the Scope Rule does not pertain to testing train crews for Rule compliance. In addition, the Carrier posits that Signal personnel have never been used to perform efficiency tests. Moreover, the Carrier notes, placing a shunt wire to create a prescribed test in accordance with its own internal safety standards and FRA regulations does not, as asserted by the Organization, disable or interfere with the proper functioning of the signal system.


In our careful review of the record in this matter, the Board finds that the case is not one of first impression. Thus, as early as 1971, the Third Division held that the use of shunts for the purpose of testing the efficiency of a train crew was work properly performed by members of the Signalmen's craft. In Award 18384, the Board provided the following guidance:

The above holdings notwithstanding, the Carrier asserts that "[sluch testing of train crews as to their efficiency in correctly responding to signal indications are performed on a routine basis across the Carrier's system hundreds of times every year without involvement of the signal craft." Assuming, arguendo, the Carrier's assertion to be true, it is well accepted arbitration precedent that the existence of any such past practice does not serve to trump clear contract language, particularly where, as here, there is ample Third Division precedent holding in favor of the Organization in substantially identical circumstances.
