Ala. Code § 37-2-110

Every railroad company in this state, on the order of the Public Service Commission, shall provide, construct and maintain adequate depots and depot buildings for the accommodation of passengers, where public necessity demands it and the revenue received at such point will be sufficient to justify it. Said railroad company, for the comfort and accommodation of its passengers, must have, when required by the Public Service Commission, at each of the passenger stations along the line of railroad operated by such company, sufficient sitting or waiting rooms, to be determined by the commission, for passengers waiting for trains, having regard to sex, which shall be suitably heated in cold weather, and supplied with sufficient fresh drinking water, when passengers waiting for trains are present, and with sufficient and comfortable chairs or seats; and connected therewith a sufficient number of comfortable privies, or water closets, to be at all times kept clean; and, in a conspicuous place at such station, a bulletin board showing the schedule time of the arrival and departure of all passenger trains. Any said railroad company must maintain a ticket office at each of said stations for the sale of tickets, together with a sufficient force of employees to transact efficiently the business and traffic thereat.
