CSX Conductor Training Week 1 Practice Test

Limited speed is a defined operating speed you must not exceed, chosen to balance safety with progress. For CSX rules, the maximum you may travel at this speed is 45 mph, so you should not go faster than that. This limit helps ensure you have enough stopping distance and time to react given typical track conditions and signal visibility. If conditions worsen or signals require it, you must slow down further. The other speeds don’t fit because 60 mph would exceed the Limited Speed cap, while 30 mph and 15 mph are below the defined limit and would indicate more restrictive conditions.
