Of course the other option is rebuilding low scale areas around existing train stations as high density apartments.

The game has changed for most big cities since post wwii mass housing. Jobs are more focussed in fewer places and cities are much larger so getting into the city can be very hard from outer suburbs.

The UK is a good example for thr models discussed. It has been building small houses for a long time (like 150sqm lots) and have a minimum density requirement across the country to make this happen (which is also about retaining farmland in the longer term). Too many too far from jobs though its exacerbating englands divide between haves (in london and some other places - large and small) and have nots (in towns and accretions to towns with more people than jobs)
