Switching Layout 14x48 Project - Bridge and Creek

Last couple of days, I have worked on the bridge install and the creek it is crossing.

I am re-using a bridge abutment design from my N scale layout re-size for TT Scale and adjusted for the layout.

Test fit of abutments and bridge

Then added a primer sealer to the abutments. Once these are dry I will apply a soupy mixture of joint compound and paint.

This is what my N Scale one looks like

I also got four TT Scale bridge shoes coming from Shapeways (photos of my N Scale ones)

TT Scale Bettendorf Trucks - Update III

Today, I received the new batch of trucks from Shapeways. I am very happy with the out come of this batch. Wheel sets have a slight tight fit that will required some reaming of the bearing journal pockets for smooth free rolling, which works for me. I have make these available in my shapeways store.

Now I have trucks for the hopper cars and anything else in the future.

Switching Layout 14x48 Project - Track and Turnout Control Part 2

Yesterday and Today, I finished up installing the slide switches for turnout control. All track shown below is glue in place too. Just need track feeder install.

Switching Layout 14x48 Project - Track and Turnout Control

I have given up on using servos for turnout control after four fail attempts at building the electronics, so I have gone back to a tried and true solution for me. SPDT Slide switches, I have used these before with good success.

First I cut some re-enforcement pads for the slide switches and start creating pockets for pads and clearance holes for wires.

 

I use a 0.025" music wire and 0.0325" brass tubing for linkage to turnouts. I just make a small channel for the tubing to fit in.

I am also gluing down track and turnouts, adding frog power wire as I go too.
