New addition for the track gang

It’s been a while since my last post and not much has been happening on the layout because of business commitments. But I did add a new tool to help me with the remaining track laying – four custom track weight/gauges.

Since I’ve been working with a machining company to produce faceplates and handles for our ProtoThrottle, I asked them if they would machine some steel to help me hand lay my track more efficiently. They agreed, so I sent them some simple drawings and, bingo, relatively heavy track gauges that will work perfectly for my code 70 rail.

These are going to be a welcome addition because they’ll hold the rail securely in place because of the steel’s weight. Plus, they will come in handy for other uses where I need extra weight to hold something in place.

Rock River bridge girder spans

I just received my two Rock River girder spans from my friend, Clark C. They came in a very well designed protective wood enclosure because of all the delicate parts. The spans look fantastic and I’m excited to get to work on prepping them for placement.

Both spans need to be reinforced with metals strips along each inside length to make them more rigid to support the weight of the trains. After that, I will prime and paint them in a dark rusty brown color, add the ties and rail and then move on to scenery construction for the piers and river scene.

Clark provided the spans so that I can get the track work up and running across the river. The lattice trusses will come later and will be attached via the side beams. Both spans measure roughly 16 inches in length.

Here is an overall view of the two spans.

This closeup shows some of the detail. There are rivets lasered into the acrylic, but it is hard to see in the photo.

Lattice girder development

Work is progressing with the lattice  truss bridges. My friend, Clark C., who’s helping me with the bridge design and fabrication is doing a fantastic job. I really appreciate his talent.

We decided the best approach would be to design and laser the girder structures for the two spans first so that I can put them in place to get the track operating. Clark has designed the bridge so that the side trusses can be fabricated separately and then attached to the girders at a later time.

Of course, once one of the trusses is complete to our satisfaction, the other three will be easy to create.

I’m very excited about these bridges because they will be my signature scene on the layout. Lattice truss bridges are not modeled very often, so they will be a truly unique feature.
