Title 49 › SUBTITLE IV — INTERSTATE TRANSPORTATION › PART A — RAIL › CHAPTER 107 — RATES › SUBCHAPTER I — GENERAL AUTHORITY › § 10708
The Board must publish a rail cost adjustment factor as often as it can, but at least once every quarter. The factor is a fraction: the top number is the most recent Index of Railroad Costs that the Board compiles or checks and adjusts for changes in cost makeup (such as different materials or types of labor), and the bottom number is that same index for the fourth quarter of every fifth year, starting with the fourth quarter of 1992. The Board must include changes in railroad productivity when it makes the factor. The Board must also publish a separate index that does not reflect productivity changes.
