OMB 2140-0043
Railroads are classified by size into groups of large, medium, and small carriers. The Board must determine the classification of each rail carrier as a Class I, Class II, or Class III railroad. Railroads with a Class I classification (large railroads) must file Annual Reports (Form R-1) under 49 U.S.C. 11145. See OMB Control Number 2140-0009 (Class I Railroad Annual Reports). All other railroads are required to compute their adjusted revenues using the “railroad revenue deflator formula,” and, if the computation derived from that formula indicates a change in a carrier’s classification, that carrier must submit a “Classification Index Survey Form” to the Board pursuant to 49 C.F.R. 1201 General Instructions 1-1 and 1241.15.
The latest form for Classification Index Survey Form expires 2026-12-31 and is listed under ICR 202306-2140-001.
