CZ top speed

[Thirdrail7]

Overspeed kicks in at 82.

And if I understand that is often followed by a trip to the Unemployment Line.

At what top speed?

10mph as per federal regulations.

It was possible in the old days,now locomotives have event recorders.

Even after speed recorders became standard, many railroads would ignore operation above the speed limit -- especially if the train in question was late. The situation began to change in the 1970s when railroads became more conscious of liability and portable radar units became available. These days, enforcement is quite strict.

The final blow came with federal certification. Even though the penalties have relaxed a bit, you're looking at decertification after 10mph over the speed limit. If you're decertified too many times, most railroads won't touch you. Your career is over. Who wants to take the chance?
