The last major change of the upper bound for a Class II railroad was in 1992, when the Florida East Coast Railway was changed from a Class I railroad to Class II. A previous change in 1991, which prevented two railroads—Montana Rail Link and Wisconsin Central—from becoming Class I, was made at the request of the two railroads, as they did not wish to take on the extra cost and paperwork associated with Class I status. Changes since then have been adjustments for inflation.
