    Here are the same tunnels on my first N scale layout...a 32x78 HCD ... 06/19/08

    This HCD was later incorporated into the original THERR (see above) :)

    Does highway bridge count?

    Is that a small sand bar, in stream middle? Or a great white shark? :)

    Well, there is not much sand in the Brazos, so it would have to be mud.

    There are three bridges slated for installation on my N Scale version of the Dawson Creek Subdivision. Pine #4 is a high deck truss bridge measuring 1,013 feet in length and 163 feet in height:

    This will be a signature scene on my layout, featuring a full size scale model of the prototype:

    Just before the railway crosses the Pine River, it spans Highway 97 on a concrete overpass:

    My N Scale version is full size, but I had to reverse and sharpen the curve to fit my layout:

    Here is the overpass in place on the layout for a test fit with a mock-up of the highway underneath:

    The other major bridge on the Dawson Creek Subdivision is the wood Howe deck truss span with trestle approaches spanning the Kiskatinaw River:

    My full scale model will be sctachbuilt from scale lumber; until then a temporary span is in place on the layout:

    That is it for my bridges; no tunnels.

    Mostly just top sections of Atlas viduct kits. But LOTS of kits.

    Plus the old AHM/Pola Scherzer rolling lift bridge for the center lift span.

    Hi Tim,

    Nice bridges you got going there. Question about the concrete bridge. Did you scratch build that one? If so, what material did you use? I need something similar but haven't been too happy with my experiments so far.

    The only bridge I have so far is this highway bridge representing Washington Route 10's crossing of the Teanaway River just east of Cle Elum on a NP layout I am building. The NP paralleled the highway and used a non-descript through plate girder bridge, so the highway bridge is just a bit more interesting to look at. The bridge is scratchbuilt from wood and paper and uses Rix railings and roadway sections.

    A log time ago in many layouts and moves now far removed from memory I had a nice Campbell wood trestle. Long since succumbed to the ravages of storage and moves. So all I have to offer is the various kits and portals that will someday hopefully see life on the new layout.

    It's just a cropped copy of Faller's advertising photo. I swore starting out I would never build a styrene kit. Then I saw this, and couldn't contemplate not having it! It'll go wherever I can find 2 feet of room for it.
