why? Its only about 3 feet deep if you ever seen it drained not that we'll ever see an underground line anywhere in Adelaide in our lifetimes Sure but how much water is underneath the lakebed? How much water is in Sydney Harbour? Yet they've tunnelled there for their metro. Anyhow, they don't need ...

It is a very nice concept. Unfortunately, if they ever go underground, they'll probably avoid tunneling under the Torrens. why?

I like the idea of the Gawler line travelling underground through the CBD and connecting with the Seaford Line. They're the lines with the highest usage so let's connect them up and run them as a proper metro service, and get building along both lines. As for north meets south, there's a similar ar...

The trams got delayed a bit this morning because a substation got struck by lightning.

In contrast to the well received suggestions of demolishing stations for the purpose of amalgamating them, I was wondering if there would be enough demand for a new station immediately north of the Onkaprainga River bridge on the Seaford line. There seems to be a modest number of houses nearby, and...

One of my earliest concepts with the Gawler line going through the CBD to Unley and onto Millswood. With also new subways running from the northeast to south and southeast.

System 4J gets my vote.

I just boarding a 3000 class on the Gawler line. I thought the days of mixed 3000 / 4000 class traffic on the Gawler line were over.

(not that I'm complaining, I just thought it was odd)

When is the realignment of Raglan Avenue scheduled to be built? It feels like they really should’ve pushed this forward, culling one set of lights in Edwardstown will be welcomed with open arms. I had a look on Google Earth history view and it looks like the buildings to the north of the east end o...

Could they save space by using rigid conductor rail in the tunnels in place of traditional overhead lines?

People in this thread advocate for electrification of that line all the time. It’s a bit of a stretch to say we’re not discussing that (whether it be health benefits or just good transport policy). The batteries are a good short term fix but they just need to get 25khz electrification done or somet...

Saw hybrid railcars 3121 and 3122 at the ARS this morning. Are they in revenue service or just testing?

We need trams in North Adelaide

I still find it strange that batteries are measured by megawatt hours instead of joules. 250 megawatt hours is basically saying 250 megajoule-per-second-hours. Power plants that have there capacity measured in megajoule-per-second-hours-per-year are even worse. 900 gigajoules is easier to say than ...

If you're going to electrify the obahn and have electric buses running on it, wouldn't it make sense to either have overhead wires, or a 'powered' rail down the centre at 'ground' level like some tram systems have to power them? I'm sure with some government funding as an incentive, the firm that b...
