Petitioners’ sole witness testified: “Yardmen are usually men who have to do with the making up and breaking up of trains, switching in the yard, and supervising the work of the yardmen, which would include, in my opinion, yardmasters and assistant yardmasters.” But his opinion as to yardmasters in this respect was based upon his understanding of the law, not upon his own use or his knowledge of the use of the term “yard-service employees.” He explained his belief that “every tribunal that has decided a dispute for men engaged in yard service, such as yard engineers, firemen, hostlers, hostler helpers, road conductors, trainmen and yardmen, have also decided cases for yardmasters and assistant yardmasters. Division 1, set up under, by agreement, in 1918, the very first board in existence, did that. The Western Train Service Board, upon which I served, did that, as evidenced by Board decisions submitted here as an exhibit.” This witness also stated that yardmasters “fit more nearly in with the yard service employees than with any other class” — a recognition that yardmasters are different in fact from yard-service employees and that they do not fit precisely within that category.
