While there are MANY forum threads here on MRH (I know, because I just spent the last half hour going through ALL of them!), NONE of them address the questions I am about to put forth.
So, a bit of background. My fiddle yard is approximately 2 1/2 feet wide, and each of the seven tracks is exactly 8 feet long, clear of the fouling point at the throat. Six of the seven tracks are paired - The one branch has a pair of tracks designated as an "Eastbound" (trains entering the layout) and a "West" (for trains exiting) fiddle track, and then for the Eastbound and Westbound mainline tracks, the Eastbound Main line splits into two tracks, as does the Westbound Main. The second branch is just a single fiddle track, as it doesn't see much traffic during a session, thus need much capacity. I figured, that since most trains will enter and exit the modeled layout via the main line, that the paired fiddle yard tracks can have, at the beginning of the session, two trains pre-built. In Diagram A, I have drawn out a basic track layout of the fiddle yard (which is to the right in the diagram)

Now, as to capacity - I model the 1950's terminal waterfront area railroad. the other end of the layout are carfloats, which have a maximum capacity of 15 cars. Also, the cars are generally of the 40ft variety, so my transfer runs will be "measured out" at 15 cars, which will consist of a two unit switcher set (EMD SW of ALCo S-type switchers), and a caboose. Yes, some cars are shorter (coal hoppers, at 34 ft) and larger (gondolas and box cars at 50ft), so there is a certain give-or-take as far as train sizes go, but a major factor was my available length of the fiddle yard (8ft per track), and didn't want my head end of a train in the yard throat, while its rear end was just leaving staging.
So, that's the background of things......My REAL question is twofold, first, an "accessibility" design issue, and second, a "differentiating between different routes" design issue. Right now, as seen in picture #1 and #2,
#1 #2
the fiddle yard is planned one flat plane of a yard. My question for issue #1 is - What track spacing is best to reach in and around tracks with the minimum chance of knocking things off adjacent tacks, and instead of buying a TON of Atlas re-railing track sections, should I bother to make the tracks flush (basically "tracks in pavement") using long strips of styrene in between the tracks, or just use a re-railers section maybe once every foot or so?
Second, the "differentiating between different routes" design issue........As I said, I have two branches and two main line routes. In my original fiddle yard design, I have the one (busier) branch elevated and cantilevered above the main route (very much akin the the prototype, as seen in picture #3.
#3
This of course, as well as a bit of an apparent access issue (apparent to me, at least) , and that and a construction issue necessitated its removal. So, this issue dovetails a bit into the first - Should I elevate and "stair step" the new yard? Not only would that differentiate the routes, but my vertically terracing the tracks by an inch each, accessibility is (I think so, at least) improved, no?
Are you with me so far? Hopefully this all makes sense, and then even more hopefully, you will all weight in.
Thought, question, comments?
