A tall, small desk upon which sits an open train register book in which NSWGR signalmen recorded the passage of trains through their track sections. There is a high stool in front of the desk. Both furniture items are of varnished wood.
The asset has a night mode which is asserted at 6pm and extinguishes at 6am.
