“ Skaggs then went to the depot to ascertain the meaning of the signal, and was told by the conductor that it was necessary to pick up certain other cars. Returning to the engine, he attempted to uncouple it from the right-hand side, but found this difficult, and Buchta, who was then on the opposite side, effected the uncoupling and said, 'Go ahead.' On Skaggs's signal, the engine started forward; but Skaggs did not know whether the cars were left so as to give sufficient clearance for an engine going onto the passing track, and asked Buchta as to this. ”
