Good start

Good job angling the front track: many people make the track parallel to the sides, which makes the whole layout more "toy train" looking.

I'm assuming that the two tracks in back are staging and won't actually be under a mountain behind on as a viewblock?

Here's a few suggestions:

Unless there's a real, real good reason for a switchback (property issues, limited approach to customer industry, etc.) most real railroads would avoid them, as it takes more track and limits the use of the switchback lead.

I'd use crossings ("X"s) instead with turnouts coming off the runaround in the center.
More efficient use of the runaround and frees up the other spurs for industry / storage.

I'd also flip the turnout at the top left (orange) so the main goes through around the top and doesn't create any crazy "S" curves, as well as matches the turnout at the top right.

Note: curved turnouts would make for a smoother run and increase the staging space at top.

Otherwise, a pretty good use of space.
You can use two short turnouts instead of the 3-way if you want (you have space).
A few large industries is better than many small ones, in my view, so it's ok to make two of the three center spurs parallel and part of one big(ger) industry.

You can never have too much storage on a small layout!
(cars can quickly get in the way of each other)

Looking forward to seeing your progress!

A couple more Ideas

(1) While I agree that real railroads would avoid switchbacks if at all possible, it's also true that they do add interest to a "switching puzzle" operating scheme, and you can probably come up with a justification for using one if you really want to (tight urban scenery with track having to snake around buildings, a stream running lengthwise through the scene and the cost of building more than one bridge to cross it, etc.)

(2) Run the lower left end siding off the end of the layout; so that it becomes your connection to the rest of the world.  Stage short trains there, bring them into the rest of the layout and send them to their intended destinations. 

(3) Having a continuous run is good, but for more operating interest, treat the rear siding as another destination to send cars to.  Add a turnout, or better yet a pair of turnouts facing different directions, and you've got a whole 'nother town to serve.  And you'll still have room for a viewblock down the center of the layout (a mountain ridge, a row of tall buldings, a row of thick trees or even a harbor with a bridge at one end or the other -- no need for a backdrop if you want to keep it portable)  to create two different town scenes separated by theoretical miles.  For operations, you'd treat the turnback curve on the right end as non-existant.  You could even make the CR track a "loads in / empties out" pair of industries when you operate, with one industry location in the front town and one in the rear town. 

(4) Personally, I like maximizing operations and maximizing room for nice scenery over maximizing track, and I wonder if having 3 sidings running to the inside left of the layout is worthwhile.  Having just 2 sidings terminate in that area would give you more room to model the industries they serve, and I don't think the extra siding adds all that much to the operating scheme.  This is just a matter of preference on my part; lot's of folks would go for 4 sidings instead of 3, and maybe even turn 3 of them into a small yard, particularly if they had a lot of rolling stock they wanted to keep on the layout.

(5) I'll suggest you remove the incline track first, then install another siding or two off the rear passing track, and leave the yard/industry area in the front until after you've played around with operating the layout like a real railroad for a bit.  By that time, you'll probably develop a better idea of whether you want an uncluttered 2 track arrangement in the left center, a 3 track arrangement like the one in your first draft plan, or a 4 track arrangement.

Looks to me like you're well on your way to having a fun layout!

Thank you!

Hi all.

Thank you so much for your help. i will try to incorporate all the ideas you gave me.

I think that the three tracks in the middle are a bit two much. I'll see what I get Just with two sidings... 

Thank you so much for all your help

Second plan

Hi.

I read a thousand times your comments, and then I read them again.

This is what I came up with:

Thank you.

2nd Plan Thnoughts

Luis,

For what it's worth, I like your second plan a lot!  Following MC Fujiwara's comment about how real railroads avoid switchbacks if at all possible, I'd probably put a small bridge crossing a little stream on the one short curved section between the passing track and the switchback -- so the reason for the switchback becomes being able to avoid the expense of installing a second bridge over that stream.  The stream could then cross under the main and run off the table on the right end just before the tunnel -- pretty easy to work a stream at the base of a hill!  On the other (left) end of your plan, the stream would cross under the main at the short straight section.  This would also help separate the front and rear scenes, where those sidings are pretty close to each other.  You might even want to bend the rear sidings a little to end them closer to the rear main line --to provide just a bit more scenic separation.  This might depend on the footprints of the industry building(s) you decide to put there. 

While operating, the tunnel would not be used -- unless of course you want to treat it as a lods in / empties out industry.  You should have places for at least a half dozen or more industries, team tracks, etc.  -- places to spot cars when you decide to have a little operating session.  GO for it! 

Funny but looking at that for some reason

reminds me of the Erie Harlem Station site at the Bronx.  The lower right could be a carfloat track . Eliminate the mountain and tunnel , place warehouses, team tracks,  and coal dealers on those spurs and you'd have a great city scene  :> )  .......DaveBranum

Scenery

Yes, I agree an urban theme work work well with this plan too.  Tall buildings could be used for a center view block; you could have the track pass under or through a large building instead of a tunnel on the right had end, and a car float instead of an interchange track running off the layout would be another way of accomplishing the same operating goal -- having a connection to the rest of the world.   

Hi all.   These plan are

Hi all.

These plan are beeing changed.. let's see what happens.

Thank you.
