Several folks got on the MRH forum connected with that March
column and disagreed. Check it out for more details. However,
they failed to show that POMwas dangerous. What they did show
is that ANY programming possibility in the hands of someone who
isn’t fully cognizant of their actions can cause problems. There is
a solution: don’t let guest operators (including club members) use
throttles that have any possibility of programming things on the
layout via any mode.
There are, as I said above, two methods of POM. What I’ll call tra-
ditional and Blast Mode.
Let’s look at traditional first. When you enter this mode, the com-
mand station asks you what loco to program. That’s a strong clue
you’re entering POMmode. You need to verify or correct-and-ver-
ify that address. Once you get past that gate, nothing you do will
impact any other loco on the layout. With this method, you can
run the loco and tweak to your heart’s content, that’s why I love it.
