Purpose
Throwing an occupied switch (i.e., there is a train occupying the track circuit) using the WGT button is not possible. In exceedingly rare cases, it is necessary to be able to throw a switch that is occupied.
Operation
The operation of the button is identical to that of the Throw Switch Button, with the exception that the switch may be occupied. The counter next to the button is useful for documenting the action in the log.
Dangers
The use of the WHT button is reserved for rare cases only! Misuse of the button can lead to derailments. Ensure that there are no trains physically occupying the switch before throwing it. At best, the switch cannot be thrown because the train is on the switch. The worst case scenario is that an occupying train will derail as part of the train is moving one way, while another part is moving the "reverse" way through the switch.
