Locomotive control system

A method comprising:

• determining operational settings to be implemented by a rail vehicle system having one or more locomotives moving along a track under a first speed limit, the operational settings determined based at least in part on a transitory second speed limit that is less than or equal to the first speed limit and which is issued for a determined segment of the track and for a determined time period, the time period having a start time and a stop time;
• obtaining a current time as the rail vehicle system approaches, enters, or moves through the determined segment;
• determining 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, performing one or more of:
• generating a prompt to indicate that the determined time period has expired,
• operating the rail vehicle system at the first speed limit, or
• modifying 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.

A system comprising a control system that is configured to:

• determine operational settings to be implemented by a rail vehicle system having one or more locomotives moving along track, the operational settings determined based on a temporary work order issued for a restricted segment of the track, the temporary work order providing a reduced speed limit for travel through the restricted segment for a defined time period, wherein one or more of the operational settings specify movement of the rail vehicle system through the restricted segment at a vehicle speed that is less than or equal to the reduced speed limit;
• control the rail vehicle system in accordance with the operational settings as the rail vehicle system moves along the track to travel within the restricted segment at the vehicle speed that is less than or equal to the reduced speed limit;
• determine a current time as the rail vehicle system moves through the restricted segment;
• determine that the temporary work order has expired based on the current time and the limited time period of the temporary work order;
• and
• in response to determining that the temporary work order has expired, prompt an operator of the rail vehicle system to confirm that the temporary work order has expired or determine updated operational settings to be implemented by the rail vehicle system to move faster than the reduced speed limit in the restricted segment.
