R120 switch

The most significant enhancement is the R120 switch. The R120 switch closes the gap between the R104 and R148 switch systems:

As you can see in the picture, the R120 siding track combination has a straight length of 5,5 standard straights.

After the introduction of the R120 switch, the only “gap” left is the R88 switch, which would have a straight length of 4,5 standard straights. We are hopful that TrixBrix is going to close this last gap as well in the future.

R104 / R120 combinations

Even before the launch, people from the community have asked what is possible with R120 switches and how the new switches relate to the R104 system.

Beside simple siding structures, the R120 switch also enables some cool new features, like turn-outs, t-junctions and dome crossings.

If you combine two of the R104 R120 turn-outs with four 90° crossings, you can even build a dome crossing like this:
