The opinion of the court was delivered
Per Curiam.These appeals involve a decision of the Board of Public Utility Commissioners which permitted Erie-Lackawanna Railroad Company to discontinue certain passenger trains in New Jersey.
On January 5, 1966 Erie-Lackawanna petitioned the Board of Public Utility Commissioners for leave to discontinue all of its New Jersey intrastate passenger service. Thereafter 36 public hearings were held, and on May 4, 1966 the Board rendered its orders denying Erie-Lackawanna’s request for total abandonment, permitting the curtailment of some passenger service on certain lines and all passenger service on others, and denying the reinstatement of trains previously discontinued by the Commissioner of the State Department of Highways who had acted pursuant to authority granted by N. J. S. A. 48:12A-16.1 et seq.
Notices of appeal to the Appellate Division were filed by all parties against the decision of the Board of Public Utility Commissioners, but by the time the case was scheduled for argument some of the parties had withdrawn their appeals because of an arrangement between the Commissioner and the Erie-Lackawanna for the restoration of part of the service.
*570We certified the appeals before argument in the Appellate Division.
The question before us is whether the actions of the Board are supported by substantial evidence which furnishes a reasonable basis for the Board’s decisions. We noted in Brotherhood of R. R. Trainmen v. Central R. R. of N. J., 47 N. J. 508, 516-517 (1966), that this type of discontinuance order is basically an administrative one and that a presumption of validity is accorded such orders. A person challenging them has a heavy burden of demonstrating that the orders have no substantial support on the facts. If a subject is debatable, the Board’s determinations must be upheld, for the judiciary can interfere with such determinations only when they are plainly demonstrated to be arbitrary. United Hunters Assn. of N. J., Inc. v. Adams, 36 N. J. 288, 292 (1962).
We have reviewed the evidence and we have ascertained that the evidence, although conflicting, furnished a reasonable basis for the actions taken by the Board of Public Utility Commissioners. In re Greenville Bus Co., 17 N. J. 131, 137-138 (1954).
