Greetings again everyone,

Before I launch a third round of questions, I'll express my sincere
thanks to all who responded to my previous queries. I was thunderstruck
with the quality and quantity of advice –it is very much
appreciated.

I expect to complete my layout infrastructural carpentry (two tables,
each is 2.0 x 4.0 meters) in a T-configuration.The leg of the T runs
East-West, and the head of the T runs North-South but on the Western
(left) side of the layout. The Eastern table therefore is the leg,it
runs left-right relative to the operator(s) and is oriented slightly
high-of-center. I'll post the schematic if anyone's interested
(I am not sure how to do so).

I've been long-distance layout brainstorming with Des Browne of
Belfast Caboose. Actually it's his brain and I contribute just a few
stormy ideas. Belfast Caboose is of course in Northern Ireland. Aside
from me, no one in Switzerland seems to have interest in S-scale. Other
than DCC components and systems, and of course basic scenery, it looks
like I'll be sourcing everything internationally. (note: I've
noticed some members bemoaning the lack of S-scale supply – trust
me, it could be worse!)

Today I have just a few queries:

I am inclined to do the track layout (on plywood tables, with foam
underlay) essentially all at once.I'd start scenery only after I am
sure everything runs properly. Reason: should I need technical
assistance I expect I'll need to call on my local Swiss shop fairly
soon after the DCC purchases, I probably cannot expect too much tutoring
many months later. My questions address magnetic coupling and signaling:

magnetic coupling

1.   I will have a variety of spurs and a freight yard, of course (which
in real-life at the Swiss Railway we call ‚Rangier
Bahnhöfe'). Does it make sense to install the magnetic decoupling
‚plates' (or whatever one calls them) immediately?

2.   How are these magnetic ‚plates' powered? Is the selection
also DCC?

3.   Are they mounted under-track or between the rails?

4.   Does one ballast over them?

signaling

I am intrigued about line side signaling. This is the single most
important aspect of 1:1 scale modeling,here in Switzerland we've
deployed a system called ETCS. Not sure what you folks in the States
use. Even with ETCS we've had accidents from time-to-time,but
it's no doubt saved countless lives. We transport more than
800,000passengers per day, and some congested stations have trains
arriving on platforms every 3-4 minutes. That's roughly 10% of the
country (not a typographical error) which makes at least one trip by
train per workday. In Zürich an estimated 60% of the workforce
commutes by rail.

1.   Will DCC allow my to automatically ‚zone' areas? What I
mean by that, can an ‚occupied' spur, siding or track length be
illuminated? I presume it would be ‚red' so subsequent trains do
not proceed.

2.   Of course I'd use S-scale signals and US-transition era bulb
configuration: I presume these are era-specific?

3.   Are there suppliers of such signals in S-scale? Can anyone suggest
a weblink?

Lastly, I'll end with an apology for my ignorance. I am probably
using wildly incorrect terms. I do so because I am translating the
French and German terms, which are our daily business languages, into
English. In Switzerland we have four official languages (Italian and
Rheto-Romanian are third and fourth; neither of them do I speak).

I've tried to do a bit of research on the internet, but the amount
of information is overwhelming, often(to me) unclear, and occasionally
contradictory.

Thanks to all for your infinite patience and Best Regards from
Hombrechtikon, Switzerland!
