This is the Camden Road level crossing at Douglas Park, NSW.
The video begins with an overview of the equipment used at the crossing. To see the crossing activate you can skip to the 3:10 mark.
The road crossing protection was installed in June 1961.
Signal on northern side - Safetran gate mechanism, McKenzie & Holland lights (converted to LED), and a WRRS mechanical bell. The bell rings from start up until the gates begin to rise.
Signal on southern side - Safetran gate mechanism, McKenzie & Holland lights (converted to LED), and a Western Cullen Hayes mechanical bell (installed in 2015, replacing a WRRS bell). The bell only rings from start up until the gates have lowered.
Both gate mechanisms at this crossing were previously WRRS type B, and were replaced by the Safetran mechanisms some time around 1994. Not sure who made the signal bases, they seem to be unmarked.
The pedestrian crossing was installed in December 1991, and has GRS semaphore signal motors and Alstom LED lights.
