After the second pour was cast and fully cured, I started to detail and assemble the bridge.
Adding stone seam lines stage 1
Then enlarging the grooves with a file, and then a steel rod of the right diameter.
Filing the stone lines
Steel rod in the 3rd stage of scribing the stone lines
I also filed bevels on the vertical edges of the small arches
Filing relief angle on small arches
I then painted the inside walls of the bridge with aged concrete
Testing assembled bridge ( no exterior paint or weathering)
In a future post I’ll talk about painting, weathering and installing the bridge in the layout
Back, finally, to casting the second side of my arch bridge, so to bring things up to date, here are a few shots of the mold and initial pour.
Wood & Sintra mold with steel wire re-enforcing rods
Pouring Hydrocal in a hurry – sets quick
and leveling off
Then back to the present starting the second pour
original cast and second pour
Both casts with spacer cut from 3/4 inch Sintra (expanded closed cell PVC sheet)
I’ll continue detailing and assembly in the next post
Some Photos showing progress, and also trying arrangements of structures for the engine servicing facility, and how these would photograph in different light (time of day-or weather)
Working with laying track and stone wall at one yard lead
Track down and stone wall further along with concrete cap.
Trying position of servicing structures
Working it out.
Camera and lighting set up after placing structures and ballast, greenery etc.
Final early morning light Photo.

Timonium GSMTS and ready to test and figure out my control panel for the yard
8 Unit pack of touch toggles with its control base and power supply
Excited to see what I can do with the
Berrett Hill Touch Toggles. Will need another 8 pack to complete the whole panel, maybe even an 8 and a 4 pack
About to attend the
GSMTS at the MD state fairgrounds this weekend. Always a good show, especially in October and February. Especially looking at Touch toggles for switch machines.

Tracks and switches going down with Dynaflex 230
Yard partially glued down
All the switches are either Micro Engineering (and Dcc ready) or Shinohara altered to be DCC friendly. Also wires soldered to frogs and fished down through holes to connect to tortoise contacts below the layout
Starting to set up various areas of my layout in different weather and time of day scenarios. will in the future try to photograph the same scene in different looks.

Decided to add wood planking to a
New Jersey International signal bridge. Thought it would add a bit of color and some signal bridges did include that feature.

Back after a summer of visiting various railroad venues, and getting down to finishing trackwork. I am modifying Shinohara code 70 # 8 switches, to work on DCC.
I am using
Micro engineering Code 70 flextrack and # 6 switches, but need some # 8s and also some # 4s on the logging branch, which ME does not offer. On the Shinoharas, I am changing to gapped PC board throw rods and connecting the running rails and closure rails with wire jumpers soldered to the bottom of the rails.
Modified Shinohara #8 code 70 switch
Also cutting gaps in the rail on either side of the frog, filling the gaps with CA glued plastic, formed to fit, and soldering a wire to the frog rails underneath to connect to a
Tortoise switch machine contacts as the switch is thrown to guard against shorting.
