Yes there is a risk. The PW transformers breaker is not fast acting. This could cause damage to an engine during a derailment or other situation. Most folks will put TVS diode protection on the outputs. See this thread. Here is another thread.

Also folks added quick acting fuses or modern breakers in line to trip much quicker than the old ZW breakers.

If you are in the market for a new transformer get a modern one with modern protection.
