If you want people to leave cars and take trains, you need to be able to at least make the same sort of average speeds that cars have.Norman wrote: ↑Sat May 16, 2020 5:27 pmAt this point in time, 160km/h is excessive for a city the size of Adelaide. The extra costs for track maintenance and rolling stock wouldn't stack up the benefits for the 5 or 6 express trains that run in each direction. If those centres of Salisbury, Elizabeth and so on become more dense then it might be a point of discussion.Goodsy wrote:The Gawler eletrification should also come with some modest line upgrades like crossing loops and station removals.

There are parts on the Seaford line that are rated at 110km/h, including near Oaklands and the extension beyond Noarlunga.
Remove Greenfields, Parafield Gardens, Chidda, Nurlutta, Elizabeth South
New station at the A20 overpass to replace Tambelin and Evanston stations
Remove Kudla and replace it with a new station at Gordon Rd
Crossing loops where needed
Just on people discussing removing stations, where else had this occurred in Australia on a large scale? I know people keep talking about those two new train lines in Perth, but even in Perth their legacy train lines still have the same amount of stations they had 50, 60 years ago. Apart from outliers like Greenfields, Marino Rocks and Kudla I just don't see the point. All those other stations like Parafield Gardens and Elizabeth South serve communities that rely on the rail network. If you want to speed up some services there are other methods like express services. But don't remove stations just because it looks good on a map or a timetable.
So, for Adelaide iirc, that's about 50kph.
Any schedule speed less than that, forget about people shifting from cars to trains.
If you can't get the numbers of passengers up, then you simply can't get the economic justification for spending money on heavy rail.
The Outer Harbor and Hills line are particularly vulnerable here. For the passenger numbers and present speeds, light rail is cheaper and can service the stops. The only thing saving both services was the rail union and its influence with the Labor Government. If the railcars come up for replacement under a Liberal Government they'd certainly look at light rail to replace the heavy rail. It's vastly cheaper.
If, on the other hand, the Outer Harbor and Hills lines ran faster...or could run faster, so that more passengers were on board and light rail couldn't handle the loads, then heavy rail and electrification would be viable.
The point being that a timetable needs to look a whole lot better to justify heavy rail expenditures. Over the past few years, about $3bn has been spent on heavy rail, and it's a pitiful number of passengers per line compared to trams.
