The board may issue public service malt and brewed beverage licenses to a railroad, pullman or steamship company permitting malt or brewed beverages to be sold at retail in dining, club or buffet cars, or the dining compartments of steamships or vessels, for consumption on the trains, steamships or vessels wherever operated in the State, except when standing in stations or terminals within a municipality wherein retail sales are prohibited. Such licenses shall only be granted to reputable persons and for fit places. The board may issue a master license to railroad or pullman companies to cover the maximum number of cars which the company shall estimate that it will operate within the Commonwealth on any one day. Such licensees shall file monthly reports with the board showing the maximum number of cars operated at any time on any day during the preceding month, and if it appears that more cars have been operated than covered by its license it shall forthwith remit to the board the sum of ten dollars for each extra car so operated. The board shall have the power to suspend or revoke any such licenses for cause after granting to the licensee a hearing before a hearing examiner. Any person aggrieved by the decision of the board in refusing, suspending or revoking any such license may appeal to the Commonwealth Court in the same manner as provided in this article for appeals from refusals of licenses.
