Abstract
A control system dictates operational settings of a rail vehicle system based a transitory second speed limit that is no faster than a current first speed limit and which is issued for a determined segment of the track for a determined time period. The control system obtains a current time, determines whether the transitory second speed limit has started, is in effect, or has expired based on the current time relative to the determined time period, and, in response to such determination, performs one or more of (a) generate a prompt to indicate that the determined time period has expired, (b) operate the rail vehicle system at the first speed limit, and/or (c) modify the operational settings of the rail vehicle system to exceed the second speed limit in the determined segment but not exceed the first speed limit for the determined segment.
