Opinion by
Judge Blatt,John B. Bigley (claimant) appeals from an order of the Workmen’s Compensation Appeal Board (Board) affirming a referee’s dismissal of his reinstatement petition.
On September 7, 1973, the claimant was injured in an automobile accident while riding in a vehicle owned by his employer, Unity Auto Parts, Inc. He initiated a trespass action against the employer on January 25, 1974, and, while that case was pending, he timely filed *450a workmen’s compensation claim on September 3, 1975. No further action on the claim was taken until February 25, 1977, when, having settled the trespass action, the claimant, through his counsel, requested that his claim petition be withdrawn. On February 28, 1977, a referee issued an order dismissing the claim. Subsequently, on September 20, 1977, the claimant filed a reinstatement petition based on the same circumstances asserted in his original claim petition. A referee denied the petition, holding that the reinstatement petition was in effect a new claim petition and therefore barred by the limitation period of Section 315 of The Pennsylvania Workmen’s Compensation Act (Act), Act of June 2, 1915, P.L. 736, as amended, 77 P.S. §602, and by the res judicata effect of the referee’s unappealed order dismissing the original claim petition. The Board upheld the referee, and this appeal followed.
Section 315 of the Act reads in part as follows:
In cases of personal injury all claims for compensation shall be forever barred, unless, within three years after the injury, the parties shall have agreed upon the compensation payable under this article; or unless within three years after the injury, one of the parties shall have filed a petition as provided in article four hereof.
In Fox v. Workmen’s Compensation Appeal Board, 33 Pa. Commonwealth Ct. 575, 382 A.2d 494 (1978), we had occasion to apply this section to circumstances very similar to those presented here. We observed there that the claimant’s “modification petition was properly treated as a claim petition in light of the withdrawal of his original claim petition . . . and was thus subject to Section 315 of the Act.” 33 Pa. Commonwealth Ct. at 577, 382 A.2d at 495. We concluded, therefore, that the “modification” petition filed after *451the statutory period had run was properly dismissed as untimely.
Although the claimant here attempts to distinguish Fox, we perceive ño substantive difference between the circumstances in this case and those in Fox. It follows, therefore, that Fox controls and that the claimant’s reinstatement petition, filed more than 3 years after the injury, was properly dismissed as an untimely claim petition.
The order of the Board will therefore be affirmed.
