<kuid2:368725:90062:4> NSWGR bracket lock for yard points, for avatar operation

Скачать

A locking mechanism that sits in line with point rodding and prevents it from moving when the lock is engaged. The bracket lock design is based on those in use by New South Wales Government Railways in the early and mid 20th century.
The Edit Properties browser allows the user to select the junction operated by this lever.
The bracket lock is operated by a signalman or safe-working officer (SWO) avatar (see the 'SWO Controller Rule' <kuid:368725:60021>1 and <kuid2:368725:15000:10> 'Safeworking Officer'). When the relevant avatar is active in the yard in which this bracket lock is placed, the avatar cannot operate the associated lever without first unlocking the bracket lock.
A naming convention must be followed to associate the bracket lock with a single-lever switching frame. If the local avatar is named '<location code>_<sequence>', the frame is named '<location code>_FRA_<frameID>' and its bracket lock is named '<location code>_FRA_<frameID>_lock'. An example of a valid localised name of this asset is 'MUR_FRA_G_lock', where the asset instance is the lock for single-lever frame 'MUR_FRA_G'.
To disengage the lock, an officer had to obtain a key (in NSW most commonly an Annett key) released from the primary yard lever frame (usually Frame A located in a signal box) or from a 'releasing switch' controlled remotely from the primary frame.
