This is my outdoor layout:

While I have made provision to connect every section of track (mostly 1 yard lengths of flexi track), only a few are yet attached. So far there is no problem with connectivity through the fish plates. However some of the points no longer make good contact between the switch rail and the stock rail. To solve this needs power routing via an accessory switch (always planned but not yet implemented).

I protect the points by covering them with pieces of scrap wood, but the track is left open to the elements (and falling apples).

I use DCC for control --- a Lenz Compact + LH30. The power transformer is in the shed so only low voltage power is outside. The control point is hinged so that it swings back under the layout when not in use.

Setting up involves turning on the power, swing out the control, add trains and buildings. I intend to add some more scenery in weather proof material. The tunnel entrance will be built up with a bit of concrete and I might even try using this for the platforms as well.

I don't think you would need booster for that size layout (unless running a lot of trains at once). Just some heavy duty wire providing extra power feeds. All I have in my shed is the transformer --- even a shed full of stuff should be able to accomodate that. Although my control point is outside, I can run in (light) rain by using an umbrella. However DCC makes it much easier to relocate the control point (or have extra points) should I change my mind.

Do you intend having a loop at the 'ends' of the line, or stop and reverse? Loops work better with children. I also like having a reversing loop.

It is easier to put the transformer somewhere with an existing mains supply and then run the low voltage output outside. If you want to run mains to a new structure you are required to get a qualified electrician to either do it or at least inspect it (and there is paper work to go with this).
