<kuid2:368725:65101:2> NSWGR LQ semaphore, mechanical main and diverge right home and call on, 22ft wooden post with platform cantilevered right, oil lamps
A lower-quadrant, manually-operated, semaphore signal with 2 dolls mounted on a platform cantilevered to the right from a 22ft post. The sempaphore spectacles are illuminated at night by oil lamps.
The semaphore arms are: 1) Home Main, above 2) Call On (extended signal state 9), both on doll directly above the post; 3) Home Main to Right-diverging Loop or Branch, on doll to right of the post.
Each semaphore has a rear blind that exposes a clear rear lens on the oil lamp when the semaphore is 'on' (STOP position) and obscures it when 'off'. By observing the status of the lamp light from the rear lens, a signalman may discern at night whether the lamp is still alight and, if alight, whether the semaphore responds to its operating lever.
For correct automatic operation the signal must be used with directional feathers to uniquely identify the 2 possible paths indicated by each semaphore. Use <kuid2:60850:23901:4> 'Sig T Feather Straight' to mark the path of the Main semaphore; and <kuid2:60850:23921:4> 'Sig T Feather Right 1 (pos 4)' to mark the path of the Loop or Branch semaphore.
The call-on semaphore cannot operate automatically. A player signalman is required to decide if it is safe to call on a train. Sessions where a player is a signalman can be created using assets such as <kuid2:96148:94051:23> 'SWO Controller Rule', <kuid2:368725:90030:5> 'NSWGR mechanical lever frame for a signal box, 18-28 levers, for avatar operation' and <kuid2:368725:15000:11> 'Safeworking Officer'.
Another way to operate the call-on semaphore is by use of driver-schedule commands <kuid2:368725:60002:10> 'Set Selected Signal State' and <kuid2:368725:60003:6> 'Set Signal Ahead'.
The distance (metres) between this signal and an approaching train beyond which the signal is held at STOP can be set by the user in the Properties editor. The deefault approach distance is 1000m, and available values are 500,1000,2000,4000 and 8000.
