I finished the single track in the corner tunnel. Ran an A-N NW2 through it.
Pulled the now unused under board Tenshodo switch machines and mounts out for re-use elsewhere.
Sorting out where the track for the new double main will actually lie (it will cross a bit of a pop-up area).

This is a shot from the stairs towards the east portal of the corner tunnel, with the NW2 just exiting. The green long gon is on the old line that will go eventually to the upper level.

This is the old west portal. Will get a new single portal, and fixed scenery bits. The orange balsa boxcar on the right is on a dead spur, switch was at the portal, now removed. The spur will either come out or be reversed.

Shot of the east portal with the NW2, showing the pop-up access area. The new tracks will cut across the toe of the mountain to the right of the pop-up. The blank spot in the support was an arch to support one of the lines, made up of old pieces of the cut up portals. I will re-use it elsewhere.

This is where the old line branches to the right and through the natural rock tunnel portal.

This shows the old double track in front of the station. The train with the caboose is the new eastward main, there will be a switch just about where the caboose is, and the eastward new main will come directly towards the camera from there. The line of boxcars to the left of the caboose are on a track that will become the new westward main, will be moved to the left a bit to maintain clearance. To the left of that is the old station house track, again, move to the left, and a switch installed. The old Walthers gas-electric is marooned on the end of that track now.

This is a shot of the outside door and the opening where the old and new bridges reside, removed for access.
