Administration or the Administrator's delegate.

    Alteration. Any change to the boiler which affects its pressure 

retention capability. Rating changes are considered alterations.

    ANSI. American National Standards Institute.

    API. American Petroleum Institute.

    ASME. American Society of Mechanical Engineers.

    Boiler surfaces. The boiler interior is all the space inside a 

boiler occupied by water or steam under pressure, and all associated 

surfaces inside that space exposed to that water and steam. The boiler 

exterior is the opposite surface of all components directly exposed to 

the boiler interior. This includes the fire side of the firebox sheets.

    Break. A fracture resulting in complete separation into parts.

    Code of original construction. The manufacturer's or industry code 

in effect when the boiler was constructed. If the exact code is not 

known, the closest contemporary code may be used provided it does not 

pre-date the construction date of the boiler.

    Crack. A fracture without complete separation into parts, except 

that castings with shrinkage cracks or hot tears that do not 

significantly diminish the strength of the member are not considered to 

be cracked.

    Dead locomotive. A locomotive unable to produce tractive effort.

    Fire. Anything that produces products of combustion that heat 

transferring components of the locomotive are exposed to.

    FRA. The Federal Railroad Administration.

    Locomotive operator. Person or entity which operates, but which does 

not necessarily own, one or more steam locomotives. This term means, for 

purposes of inspection and maintenance responsibility, the entity 

responsible for the day-to-day operation of the steam locomotive, or the 

delegate thereof. This entity may be a railroad or a person or persons 

who operate a steam locomotive under contract for a railroad.

    Locomotive owner. Person or entity which owns, but which does not 

necessarily operate, one or more steam locomotives that is operated on a 

railroad to which this part applies. For purposes of inspection and 

maintenance responsibility, this term includes that entity's delegate as 

well.

    MAWP. Maximum allowable working pressure as specified by the steam 

locomotive specification FRA Form No. 4. (See appendix C of this part.)

    NBIC. National Board Inspection Code published by the National Board 

of Boiler and Pressure Vessel Inspectors.

    NDE. Non-destructive Examination.

    NPS. Nominal Pipe Size.

    Person. An entity of any type covered under 1 U.S.C. 1, including 

but not limited to the following: a railroad; a manager, supervisor,

facilities; any independent contractor providing goods or services to a 

railroad; and any employee of such owner, manufacturer, lessor, lessee, 

or independent contractor.

    Railroad. Any form of non-highway ground transportation that runs on 

rails or electromagnetic guideways and any entity providing such 

transportation, including commuter or other short-haul railroad 

passenger service in a metropolitan or suburban area and commuter 

railroad service that was operated by the Consolidated Rail Corporation 

on January 1, 1979; and high speed ground transportation systems that 

connect metropolitan areas, without regard to whether those systems use 

new technologies not associated with traditional railroads; but does not 

include rapid transit operations in an urban area that are not connected 

to the general railroad system of transportation.

    Renewal. Replacement in kind with a newly manufactured or 

remanufactured (restored to original tolerances) component. Materials 

shall be suitable for the service intended.

    Repair. Any work which results in a restoration in kind.

    Serious injury. An injury that results in the amputation of any 

appendage, the loss of sight in an eye, the fracture of a bone, or the 

confinement in a hospital for a period of more than 24 consecutive 

hours.

    Service day. Any calendar day that the boiler has steam pressure 

above atmospheric pressure with fire in the firebox. In the case of a 

fireless steam locomotive, any calendar day that the boiler has steam 

pressure above atmospheric pressure.

    Stayed portion of the boiler. That portion of the boiler designed to 

require support to retain internal pressure by the addition of strength 

members, such as staybolts, braces, diagonal stays, tubes, etc.

    Steam locomotive. A self-propelled unit of equipment powered by 

steam that is either designed or used for moving other equipment. This 

includes a self-propelled unit designed or used to carry freight and/or 

passenger traffic.

    Unstayed Portion of the Boiler. That portion of the boiler designed 

to be self-supported in retaining internal pressure without additional 

strength members such as staybolts, braces, diagonal stays, tubes, etc.

    Wastage. A reduction in the thickness of a mechanical component, 

such as a pipe or sheet.
