49 C.F.R. § 234.3 Application.
Title 49 - Transportation
This part applies to all railroads except: (a) A railroad that exclusively operates freight trains only on track which is not part of the general railroad system of transportation; (b) Rapid transit operations within an urban area that are not connected to the general railroad system of transportation; and (c) A railroad that operates passenger trains 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: (1) A public highway-rail crossing that is in use; (2) An at-grade rail crossing that is in use; (3) A bridge over a public road or waters used for commercial navigation; or (4) A common corridor with a railroad, i.e., its operations are within 30 feet of those of any railroad.
