**Rail is measured differently from road**
Road traffic noise is assessed on an 18-hour average. The Department of Transport and Main Roads' March 2019 interim guideline for operational railway noise and vibration sets criteria including a Single Event Maximum — the loudest moment of one train passing — as well as a time-averaged level. A road is a condition; a train is an event. Much of what passes at night is freight; the network manager says it neither owns nor operates those services, and that most run outside daytime passenger hours.
**If the house shakes, no fence will help**
The same guideline sets criteria for groundborne noise and vibration as well as airborne noise, which decides whether there is anything to buy. A fence stands in the airborne path and can only interrupt sound moving through the air. What arrives through the ground has no airborne path to interrupt, so no fence of any kind affects it. If what wakes you is the house moving rather than the air carrying sound, an acoustic fence is the wrong purchase and an acoustic consultant is the right call.
**What a fence has to work with here**
Boundaries touching corridor land run short: 75 of them, median near 17.9 m. The road authority's code is blunt: a barrier does anything only where the view from source to receiver is shut off, and over a run that short, against a corridor about 31 m wide, flanking around the ends becomes the controlling path. On four tracks the near rail can be screened and the far one not. Its Noise Fences specification allows no gap anywhere. Elevation sampling suggests the corridor runs substantially at grade, the case a boundary can work with — but from a 30 m model too coarse for a short cutting, describing the suburb rather than an address. If it is raised where the housing is, the answer changes. That code also records that a barrier cannot fix isolated loud events.
**Where a train noise complaint goes**
Not to the council. Schedule 1 of the Environmental Protection Act 1994 puts noise from the ordinary use of rail transport infrastructure outside the environmental nuisance provisions, along with nuisance caused in maintaining a railway. State guidance directs rail noise to the rail authority or operator first, then to the Department of Transport and Main Roads if it stays unresolved. The network manager states it does not run the freight services, so the operator may be the first call; Queensland Rail publishes a customer feedback and enquiry channel. None of that is fencing work; what RYNO prices is the boundary.
