SUPPLEMENTARY INFORMATION: Under part 211 of title 49 Code of Federal
Regulations (CFR), this document provides the public notice that by
letter dated October 4, 2025 UPRR petitioned FRA for an extension of a
waiver of compliance from certain provisions of the Federal railroad
safety regulations contained at 49 CFR parts 229 (Railroad Locomotive
Safety Standards) and 232 (Brake System Safety Standards for Freight
and Other Non-Passenger Trains and Equipment; End-of-Train Devices).
FRA assigned the petition Docket Number FRA-2005-21179.
UPRR requests extended relief from 49 CFR 229.49(a)(1), Main
reservoir system, and Sec. 232.103(o)(2), General requirements for all
train brake systems, for locomotives having a safety valve on the main
reservoir, which prevents accumulation of more than 25 psi above
maximum working pressure. In the petition, UPRR seeks to continue
allowing locomotives to have their main reservoir safety valve set at
150 pounds per square inch (psi) with a maximum working pressure of 125
psi. In support of the relief, UPRR states that the waiver ``reduces
the risk of [a locomotive] having the safety valve blowing when . . .
in a consist with [MU] locomotives that have an air system pumping at
130-140 psi.''
A copy of the petition, as well as any written communications
concerning the petition, is available for review online at

Interested parties are invited to participate in these proceedings
by submitting written views, data, or comments. FRA does not anticipate
scheduling a public hearing in connection with these proceedings since

Communications received by February 11, 2026 will be considered by
FRA before final action is taken. Comments received after that date
will be considered if practicable.
