About this blog

This blog is about my current model railroad layout project; The N scale "Summit" layout, which is a freelanced interpretation of the Southern Pacific Tehachapi tunnels and their surroundings. Or at least, that is what it is meant to be. What it will turn out to be is another matter. The banner photo above shows what I want to recreate in N scale.

Turnout test car

Since I am currently struggling with a number of handlaid turnouts, when time permits, I realized I needed a good way of testíng them. I wanted a test car that, when pushed across the turnouts, exposed as much as possible of the wheels and the rails. Since the tolerances required by a turnout very much depends on the type of wheels you intend to use on your cars I decided to build my car using Fox Valley wheels, which is the type of wheels I have decided to use for this layout.

This is what I used to build the car, and is stuff I already had at hand
- a pair of old trucks with Rapido couplers
- a couple of truck king pins
- a few washers
- a piece of Plastruct rectangular tubing for the beam.
- four Fox Valley wheels

I started by removing the Rapído couplers from the trucks. I then cut the tubing to the length of a 50 ft car and drilled a hole at each end, large enough to accept the king bin. Then it was simple matter of mounting the trucks to the beam (tubing), with a number of washers in between so that they would swivel freely, and then install the wheels. The complete project took no more than 10 minutes.

Here are a couple of pictures of the finished car.
