Geometry: R104 Curved Switches

The idea of the R104 curved switch is to initiate two R104 curved sections that come out with a track distance of exactly 16 studs after 90° (from track middle to track middle).

The concept also works perfectly to create track switches within a 90° R104 curve section.

The concept can be extended by an infinite number of parallel tracks in the curve section.

There is also a 45° version of the R104 curve switch. The idea is similar as for the 90° degree version.
The difference is, that the parallel tracks come out after 45° already.

The 45° concept also works with parallel tracks.

This concept can also be extended by an infinite number of parallel tracks in the curve section.

Two 45° R104 curved switch section can be combined to form a double cross over within a 90° R104 curve section.

The example shows a compact entry to a 6 track station built with two R104 45° curved switches, three standard R104 switches and one R104 double crossing.

The third type of the R104 curved switch (SW-R104CR-32 / SW-R104CL-32) has a straight part of two standard straights (2×16 = 32 studs). Consequently, the two branching tracks come out with a track distance of 32 studs after a turn of 90°.

This switch can be combined with the 45° version of the switch.

The 32 stud version gives you more options especially when designing complex switch fields.
