Ok, let's try it again:
A circuit breaker protects against current overloads. It goes in line with one of the power leads to the track. You only need one.
A TVS diode protects against voltage overloads (of short duration, i.e.. spikes). It goes across the power leads to the track. Several, spaced around the layout are recommended.
