The Brotherhoods contend that the collective bargaining agreement between the parties of September 25, 1964, was violated by Pacific Fruit Express (PFE), when, in October, 1979, it announced that it was abandoning its heavy repair facilities in Roseville, California, and transferring the service there offered and the workforce providing that service to its facilities in Tucson, Arizona and other locations. Contending that PFE’s right to so act presented a major dispute under the Railway Labor Act, 45 U.S.C. § 151 et seq., the Brotherhoods brought this action seeking an injunction to preserve the status quo pending resolution of the dispute. The district court denied the motion for preliminary injunction and dismissed the action. This appeal was then taken. We affirm.

The agreement of September 25, 1964, article I, § 2, grants to PFE the right to transfer work and to abandon, discontinue or consolidate facilities or services. It would appear that PFE’s right to abandon its facilities and transfer work presented a question of interpretation of the provisions of article I, § 2, of the agreement, and thus would present a minor dispute under 45 U.S.C. § 153 , First (i) — one “growing out of * * * the interpretation or application of agreements concerning rates of pay, rules or working conditions” — to be resolved by the National Railroad Adjustment Board or by mediation procedures on which the parties have agreed. 1

The Brotherhoods point out that concurrently with the announcement by PFE of its transfer of work and abandonment of facilities, its parent corporation, Southern Pacific Transportation Company (SPT), announced the transfer to Roseville of some of its heavy repair work. The Brotherhoods contend that this indicates that the action taken by PFE was not abandonment of facilities, but a coordination or merger of its facilities with those of SPT. They argue that this action is not covered by article I, § 2, and that their right to take such steps presents a major dispute.

The district court rejected this contention. It held that the agreement was “arguably susceptible to defendant’s construction,” and was thus a minor dispute under the holding of this court in Switchmen’s Union of North America v. Southern Pacific Co., 398 F.2d 443 , 447 (9th Cir. 1968). We agree.

In Order of Conductors v. Pitney, 326 U.S. 561 , 565-67, 66 S.Ct. 322, 324-325 , 90 L.Ed. 318 (1946), the Supreme Court dealt with the propriety of an injunction under these circumstances:

We adopt this reasoning here and affirm the district court’s decision to deny preliminary injunctive relief and to leave the resolution of the dispute to the mediation procedures agreed to by the parties in their agreement of September 25, 1964.

The Brotherhoods also urge that it was error for the district court to dismiss the entire action without having first expressly ordered that the hearing on the preliminary injunction be consolidated with the hearing on the merits under Fed.R. Civ.P. 65(a)(2). Appellants argue that dismissal of the action in this manner denied them an opportunity for discovery. We conclude that while it might have been preferable for the district court to have given notice, under the circumstances of this case the de facto consolidation was not reversible error.

The issue before the district court on the merits of this case was not how the agreement should be interpreted. That, as the Supreme Court noted, is a factual question that can be “intricate and technical.” Order of Conductors v. Pitney, supra, 326 U.S. at 567 , 66 S.Ct. at 325 . That question remains to be decided in the proper forum, and in that forum the Brotherhoods will have ample opportunity to press for their position on the facts.

The question before the district court and before us is who shall decide that factual question: whether the courts should interpret the contract or whether we should leave that task to the National Railroad Adjustment Board or to mediation pursuant to agreement. This question is one of law, and, as we have noted, under the holdings of the Supreme Court and past holdings of this court, the answer is clear.

Judgment affirmed.

. The mediation procedures agreed to by the Brotherhoods and PFE in their agreement of September 25, 1964, are in accordance with 45 U.S.C. § 153 , First, which does not prohibit the creation of mutually agreed upon special boards of adjustment “for the purpose of adjusting and deciding disputes of the character specified in this section.” The parties do not dispute that use of this special board of adjustment rather than the National Railroad Adjustment Board established in § 153, First, has no effect on the propriety of preliminary injunctive relief in this case.
