Finally, from the decades of disagree,ment, the house had began to crack, and holes began to appear in the floor. Fixing up the house would be even harder than getting the paint, so instead to decide to buy lots of fancy looking couches to put in the house, to mask up the holes and the decay.
The couches will still fall through the holes, no matter how expensive and fancy they are. You must fix the rest of the house to get any real value from it.
This is like the network today. Therefore, there are several way to fix the problems. Some of them are insane, some are good.
1. Shut down the entire network for 6 months. Replace all the track and all the signals with high capacity signalling. Add a 3rd track to every single line. Fix all the broken layouts.
2. Close the whole network. Rip up all the tracks, and turn them into roads. Give the new paved roads right of way everywhere, and have a toll charging exactly the same as the train ticket. Build huge underground parking areas at every station, to hold the capacity of the line. 125,000 spaces at Flinders St.
3. Pave the whole line. Replace trains with trams. Have constant trams running every 30 seconds through every station. Have buses running along the line as well. No private cars of parking lots.
4. Replace entire track with super-advanced travelators. Multiple widths, with muliple speeds. Faster than the train network. Allows you to not wait for a train and to get off whereever you want.
