I have expermineted with this way of building station for a while to… i don’t have that huge of a city, but almost.
I found that having lines that goes right past the station increase capacity quite a lot. There have always been space between the station and the tunle for me to build traffic light.
Also i usualy build the roads quite a bit closer, the houses usually fill up the soil under and can be built almost ontop of the station, it look like a lot waste space to me….
But other, real nice.
