I'm not sure that's the issue. According to Wikipedia (too lazy to search
elsewhere) an electrical signal propagates at 2/3 the speed of light or better.
The DCC '1' is 58 microseconds, which if my math is right is 10,000 meters. How
big are these loops?
I think sometimes we should just go with empirical data, and say that people
with loops have discovered that if there is a break, the decoders work more
reliably. If there are snubbers, even better.
BTW: according to Wiki, the signal propagates faster in uninsulated wire.
