	Sometimes it is necessary to manually lock a switch. This can happen, for instance, when engineering work is occurring in the area and it would otherwise be possible to forget that traffic cannot enter. Locking a switch manually is done using the button of the switch being locked, together with the [[Lock Switch Button]] (WSpT). Unlocking a switch is achieved by pressing the switch button together with the [[Unlock Switch Button]] (WESpT). When a switch is manually locked, a red light next to the switch becomes lit.

	Double slip switches are represented as X-shaped tracks with a central button. A double slip switch is actually two simple switches combined. There is a light behind each of the four branches that indicates various states of the switch. Next to the switch are four circular lights that indicate the locking statuses of the switches. The switch that opens left is referred to as the "a/b" switch, while the rightward opening switch is "c/d".		Double slip switches are represented as X-shaped tracks with a central button.

	Double slip switches (and single slip switches) have black rectangles next to the central vertex to indicate the paths that trains may take when traversing. In a double slip switch, all paths through the switch are possible, while a single slip switch has 1 out of 4 paths not possible. See [[Single Slip Switch\|single slip switch]] to compare.

==Operation==
The operation of a double slip switch is almost identical to that of a simple switch. Since there is only one central button for both switches, the [[Switch Selection|switch selection]] must first be set to the desired a/b or c/d switch. Once the selection is set, each switch can be thrown using the WGT button or locked/unlocked using the WSpT/WESpT buttons.

==Locking Indicators==
Switches can be locked for one of two reasons: locked as part of a route or as flanking protection, or, locked manually. Each of the switches within a double slip switch have their own pair of manual lock and route lock lights.

===Route Lock===
When a switch is part of a route or provides flanking protection, a white light becomes lit next to the switch. This indicates that the interlocking system is preventing the switch from being thrown into another position, and is one of the factors that prevents conflicting routes.

===Manual Lock===
Sometimes it is necessary to manually lock a switch. This can happen, for instance, when engineering work is occurring in the area and it would otherwise be possible to forget that traffic cannot enter. Locking a switch manually is done using the button of the switch being locked, together with the [[Lock Switch Button]] (WSpT). Unlocking a switch is achieved by pressing the switch button together with the [[Unlock Switch Button]] (WESpT). When a switch is manually locked, a red light next to the switch becomes lit.
