Sorry of this is already well known or documented, but if I add a
booster amp to my Lenz DCC system do I need to isolate the sections it
powers or can it simply be coupled to the other end of the same track
as the main amp?

It must be isolated.

You can't (shouldn't) connect two boosters to the same piece of track.

OK, thought so, thanks. Trivial to do, so no biggie. I guess it can
handle the brief short caused by a loco passing over the gap.

It should be able to.

You probably need to connect the second booster to a specific
connection on the first, rather than merely daisy chaining it from the
first boosters track output. This is so that the signal delays from
the command station are equal through the two boosters and the track
signals are as closely in phase as possible. It's nothing like as bad
as a power to ground short.

I'm sure Lenz provide wiring instructions on how to do this.

I'm assuming the new section doesn't form a reverse loop or wye, etc.

Don't know if you've bought this yet but it may pay you to join the NMRA
- there *significant* savings on Lenz products for members. e-mail me
for details.
