An outside slip switch is similar to the double or single slip switches described above, except that the switch blades are outside of the diamond instead of inside. An advantage over an inside slip switch is that trains can pass the slips with higher speeds. A disadvantage over an inside slip switch is that they are longer and need more space.
The Boston and Maine Railroad used flying switches at White River Junction from mixed, freight and passenger, trains and had a fatal accident involving one on 8 March 1889.

Double trap points are a full turnout, leading to two tongues. Usually the tongue nearer the main line is longer than the other.

The rail on the outside of the passing loop is sandwiched by the two flanges same as the rail in the single track section, and there is no break. The inner rails have cuts where the cable and flanges of the outer wheels pass. Wide wheels pass the cuts without hindrance. Unlike an ordinary railway switch, an Abt switch has no moving parts.
The point machine (in this case an electric motor) and associated mechanism used to operate this switch can be seen to the right in the picture. A point machine (also known as a point motor, switch machine or switch motor) is a device for operating railway turnouts especially at a distance.
