49 C.F.R. § 230.2 Applicability.
Title 49 - Transportation
(a) Except as provided in paragraph (b) of this section, this part applies to all railroads that operate steam locomotives. (b) This part does not apply to: (1) A railroad with track gage of less than 24 inches; (2) A railroad that operates exclusively freight trains and does so only on track inside an installation that is not part of the general system of transportation; (3) Rapid transit operations in an urban area that are not connected to the general system of transportation; or (4) A railroad that operates passenger trains and does so only on track inside an installation that is insular, i.e., its operations are limited to a separate enclave in such a way that there is no reasonable expectation that the safety of the public—except a business guest, a licensee of the railroad or an affiliated entity, or a trespasser—would be affected by the operation. An operation will not be considered insular if one or more of the following exists on its line: (i) A public highway-rail crossing that is in use; (ii) An at-grade rail crossing that is in use; (iii) A bridge over a public road or waters used for commercial navigation; or (iv) A common corridor with another railroad, i.e., its operations are conducted within 30 feet of those of any other railroad. (c) See appendix A of part 209 for a current statement of the FRA's policy on its exercise of jurisdiction.
