What is the speed for operating a locomotive that is not equipped with an event recorder?

The correct speed for operating a locomotive that is not equipped with an event recorder is 30 mph. This regulation is in place to enhance safety and ensure that the locomotive can be operated at a speed that allows for adequate stopping distance, thus reducing the risk of accidents. The event recorder serves as an important safety device by monitoring various operational parameters, and locomotives without this equipment are typically subject to more restrictive speed limits to mitigate potential risks.

Locomotives that are not equipped with such technology are considered less capable of providing detailed operational data in the event of an incident, hence the necessity for lower operational speeds. This standard reflects a cautious approach to safety in railroad operations, maintaining that all equipment operates within parameters that allow for safe maneuvering in various conditions.
