A tale told to me many years ago by a Youngstown Model Railroad member (2 rail DC powered by car batteries)...One night someone dropped a nail and it went across the tracks and it did weld. Available instantaneous current will get you every time.
I designed my own O scale DCC decoder and used 40A MOSFETS. Purely a matter of convenience with no expectations of needing that amount of current.
