A railroad company may not transport an employee to or from work on a caboose or locomotive unless the railroad company provides a fixed seat with a back support for the employee. To protect the health and safety of employees, a railroad company shall: install and maintain water or chemical toilet facilities on each caboose used for service beyond a 15-mile radius from a point of dispatchment within the State for use by employees, unless the caboose is a temporary substitute for one regularly used for the service; and enclose all toilet fixtures, within the caboose, in a separate compartment of sufficient dimensions that is ventilated properly. This subsection does not apply to any caboose: operated on tracks of less than standard gauge; normally used only during daylight hours; operated only within a 20-mile radius from point of dispatchment; or temporarily substituted for a regular caboose. To protect the health and safety of employees, the Commissioner shall require each railroad company to install and maintain: two or more electric marker lights on the rear of each caboose in service; and one electric light for clerical work within each caboose in service, for which the railroad company shall determine the source of electricity and type of appliance. A railroad company may not have a common towel or common drinking cup available for use on property of the railroad company. In this section, “railroad train” has the meaning stated in § 21–101 of the Transportation Article. This subsection applies to a railroad train used in connection with the movement of railroad freight that shares the same rail corridor as a high–speed passenger or commuter train. This subsection does not apply to a railroad train used in connection with the movement of railroad freight involving: hostler service; or utility employees in yard service. A railroad train used in connection with the movement of railroad freight may not be operated in the State unless the railroad train has a crew of at least two individuals. Subject to subparagraph (ii) of this paragraph, a person who willfully violates this subsection is subject to a civil penalty assessed by the Commissioner of: except as provided in item 2 of this subparagraph, a fine not to exceed $10,000; or if the person previously committed a willful violation within the immediately preceding 3 years, a fine not to exceed $25,000. A railroad company shall be solely responsible for the actions of the agents or employees of the railroad company that violate this subsection.
