A railway with no trains
A brick-and-earth mouth opens in the bush beside a suburban road. That’s Ernest Junction Railway Tunnel, at 797 Ashmore Rd, Molendinar. Dozens of cars pass it every minute, and almost nobody slows down.
The tunnel is a leftover from the South Coast railway. That line once carried trains from Brisbane down to Southport and on toward the Tweed, until the Queensland government closed it in 1964. The rails came up and most of the route went under roads and houses. This stretch of cutting and tunnel didn’t.
Expect a structure, not a museum. You won’t find a ticket window, a gift shop or a guided tour. You get a heritage-listed piece of engineering and a short walk to reach it.
Why “Junction” matters here
The name is the history lesson. Ernest Junction was where the railway split. One branch ran east to Southport, the Gold Coast’s original seaside town. The other carried on south toward Coolangatta and the New South Wales border.
That split shaped the coast. Holidaymakers from Brisbane arrived by train long before the highway era, and junctions like this one decided which towns grew first. When you stand at the portal, you’re on the line that brought the first beach crowds south.
Today the bush has taken back the approach cutting, so the tunnel feels older than it is. Look for these things:
- The portal itself: the arched face of the tunnel, where the builders’ work is easiest to read.
- The cutting walls: the trench that guided trains into the hill, now softened by vegetation.
- The alignment: stand back and you can see the gentle curve and grade a steam locomotive needed.
Getting to Molendinar
You’ll need a car or rideshare. Molendinar is mostly light industry and suburbs, a short drive inland from Southport and close to Ashmore and Parkwood. Ashmore Road is a main arterial road, so put the exact street number into your map app. If you just search the suburb, you’ll drive straight past.
Public transport gets you close but not to the door. The G:link light rail reaches Griffith University and Southport, and from there a local bus or rideshare covers the rest. Check current routes on the Translink website before relying on a bus.
Parking isn’t a formal car park. Pull off where it’s legal and safe, away from driveways and business entrances, and walk the last stretch.
Light, mud and the inside of a hill
Google lists the site as open 24 hours, which simply means there’s no gate time. That doesn’t make midnight a good idea. Go in full daylight, when you can see the ground and the traffic can see you.
A disused tunnel collects water. After the Gold Coast’s summer storms, the floor and the approach can turn to standing puddles and slick clay. Bring these:
- Closed shoes you don’t mind getting dirty.
- A torch or your phone light, because daylight fades quickly once you’re inside.
- Insect repellent, since damp bush on the coast means mosquitoes most of the year.
- Water, because there are no facilities on site.
The cooler months, roughly May to September, are the most comfortable. They’re drier, the bush is less humid and snakes are less active.
Treading lightly at a heritage site
Treat it as a protected place, because it is one. Some things matter more here than at a staffed attraction:
- Respect any barriers. If a portal is fenced, gated or signed, stop there. Old tunnels often shelter wildlife such as microbats, and closures usually protect them or you.
- Don’t climb the brickwork. Old mortar crumbles, and the heritage value is the original fabric.
- Keep noise and light low near the entrance if you can see roosting animals.
- Take everything out. No bins, no staff, no cleaning crew.
Photographers get the best shot from outside, framing the dark arch against the green of the cutting. A tripod helps in the low light under the trees, and that’s also why a flash inside adds little.
How long, and what to pair it with
Plan on 30 to 45 minutes, a bit longer if you like to read the landscape for traces of the old line. It’s a detour, not a day out. The easiest plan is to combine it with something nearby.
Good pairings within a short drive:
- Southport, the junction’s original destination, with the Broadwater parklands along the water.
- Griffith University’s Gold Coast campus area in Parkwood, on the light rail line.
- Surfers Paradise, further south, if you want to see what the railway’s beach traffic eventually grew into.
The quiet end of the Gold Coast
Most visitors to the Gold Coast never leave the beach strip, so a tunnel in Molendinar stays a quiet find. You’ll often have it to yourself, which is part of the appeal. It’s also a reason to tell someone where you’re going if you head in alone.
Come with low expectations of polish and plenty of curiosity. In return you’ll see the railway that opened up this coast, on one of the few stretches that wasn’t turned into road.
Frequently asked questions
Where exactly is Ernest Junction Railway Tunnel?
It's at 797 Ashmore Rd, Molendinar QLD 4214, a short drive inland from Southport on the Gold Coast. Enter the full street address into your map app, because the site is easy to miss from the road.
Can I get there by public transport?
Not directly. The G:link light rail reaches Southport and Griffith University, and a local bus or rideshare covers the last stretch. Check current bus routes on the Translink website before you go.
Is it open at night?
Google lists it as open 24 hours because there's no gate, but go in daylight. The ground is uneven and often wet, and Ashmore Road is busy.
How long should I spend there?
About 30 to 45 minutes is enough to see the portal and cutting. Pair it with Southport or the Broadwater parklands nearby.
Can I walk through the tunnel?
Only where it's clearly open and safe. If the portal is fenced, gated or signed, stay outside, since closures at old tunnels often protect wildlife or visitors.
