oops - I didn't make myself clear...
The original staging was in a seperate 'room', so from the layout side it looked like this...
... which I think looks better than the arrangement above. However from the staging side it looked like this...
.. and I
really didn't like the thru-the-wall thing, which is overcome in the arrangemnt a couple of posts up the page.
In the case of what you've done (provided you have room behind where the camera is), I would have continued that curve to run parallel with the backdrop. Rather than going through the backdrop the train would drive around behind it
Yep, there is a bit of room behind the camera, and you have pretty much nailed the arrangement...
(that vertical 'particle board' bit in the foreground is not visible on the route, the screenieis taken through the back wall of the staging room)
EDIT Eureka MOment!!!! The solution is to make the room side look like the arrangement in this post, but leave out the brick wall and door on the staging side! That way the layout end view is like in this post, but the view back from the staging yard is through the transparent wall and into the layout room exactly like the post a couple above. Best of both worlds!
