A derailment yields robust sparks and actually leaves spot weld like marks on the rails. Its better to breakup your layout into power districts, each districts having its own brick, with a gap in the center rail to isolate the districts.
For those that want to run 360 watts/20 amps to the track, this can safely be done (without sparks) using the PSX-AC electronic circuit breaker. Do a forum search to learn more about it.
