We are 'challenged' for height, as the layout is going 'under the eaves'.. to trees we do have do not look too bad. There is one larger specimen.
Cost (as you say) will be a big limitation on how much, and how fast things progress.. We have to 'self-fund', so have some railway books (some from the auction), a little excess stock, and alla the 'junk' in the other end of the room..
Unfortunately, a lot of it is junk, so we will not make much from it..
Initially, we will have Wernigode running, which nearly goes to the end of the room..
Then we need to make the building 'safe' for public access. - Lights, power, handrail to stairs, 'means of escape' in case of fire. THEN we let 'em in!..
Stage two will see Brocken put up, and the re-working of the boards to bring it down the other side of the room.. Then new boards, and track, to make the turn to join the two up.
The additional 'outer loop' will be added to tis side as we go.. we will then go round the end of the second room, and when we get to the stairs, stop for now.
We will form the 'break-through' above the stairs, and at that point we can then take down Wernigode to allow us to re-model the back of it to allow the 'loop' access on that side.
The idea is that the main layout will remain DCC only, and the outer loop can be switched between DCC and analogue.
Have ideas that where it comes out of the stairs in the second room, that side of the room could become a 'Rockies / desert themed section.. A 'home' for the visiting US outline stock.
I reckon it could take us a year to get to that stage though..
