Anyway, as this city grows, it's fairly widely accepted that we need more trains. The problem is that most of the potential rail corridors have been sold off by the Government over the years. That's where my idea comes in. We have plenty of wide roads, and a couple of motorways in places where trains don't currently operate. If we simply lay track on the existing roads, we have a ready-made rail network. Allow me to illustrate.

Of course it means some of the cars get shafted when the motorway gets narrowed. But after all, the average occupancy rate is 1.4 people per car. An 8-car train can carry more than 1000 people.
The main problem I have is fitting the stations on the road too, so people can actually get on and off. The other challenge is getting the trains to climb the steep sections of the road. Our trains are only rated to climb slopes up to 3%, and a motorway could be twice as steep. In an ideal world, we could use these little beauties which have no problems with hills, but I don't see that happening.
I suppose I'll just have to keep dreaming.
Edit: I forgot to acknowledge this site where I found the actual train in the images above. If you like trains, this site will make you happy:
Also, I stumbled across a brilliant discussion where people were suggesting improvements to metropolitan train and subway networks around the world here. The proposed CityRail suburban network is pretty awesome.
