The first step was to have different for the stock rails and switch rails, with the switch rails being about 25 mm 0. The wide range of turnouts and crossings in this series includes every type, and the geometry of this range has been cleverly designed to make it easy to build convenient, complex and aesthetically pleasing formations using combinations of small, medium and large radius turnouts and crossings. A narrow gauge stub switch.
Perhaps more importantly, there is usually no difference in cost between a single slip and a double slip. We have now determined that I have 2 types of double slip turnouts,.

Alternatively these substitution track segments can be wrapped around a rotating cylinder, creating a triangular truss or a two sided plate. This can be assembled out of several appropriately cut and bent pieces of rail or can be a single of manganese steel. The driver has a separate switch to control the magnet, thus switching is no longer dependent on power draw of the tram simplifying the procedure somewhat. The points are set to connect the upper left and lower right tracks.
Hinges and high stress points are always double reinforced. The letter would define the length and hence the radius of the switch blades and the number would define the angle of the crossing frog. Works great so long as I have it lined up right. No magnetic field when passing the relay means retain the blades in whatever the position they were.
