I did however, add a diode in parallel with the lamp output
in case I decide to run an inductive load such as a
relay or motor on the lamp output.

One thing to note, since the DCC decoder drops the voltage
somewhat, the actual train motor is only seeing about 7V.  This
means the locomotives aren't as zippy as with the standard
train regulator.  Nonetheless, if you're operating a few trains with
5-6 cars each, it shouldn't be a problem.  For a large club layout,
an external booster is probably advisable, though.

Mucho appreciated Mark.

The Diode--any diode will do?  and just solder it across the connector output?

Take care,

Dave
