I was impressed by Sloterdijk station in Amsterdam. It's a cross shape through station in all directions. Pure simplicity. No bay/terminal platforms at all. Trains literally every couple of minutes. Quick & simply short connection routes from one platform to another, literally up/down stairs or lifts from east to north, west to south, etc. Never seen anything like it. There seemed to be a huge loop around the built up area so that trains leaving Amsterdam central had two routes into Sloterdijk, either use the loop and approach the station from North to South for southbound trains, or cut through to approach from the East for westbound trains. The sheer number of trains and passengers it could shift at peak times was pretty amazing. What facilitated the very intensive service was that trains weren't all moving across points to get to random platforms - trains in each direction were all from the same platform(s), no bi-directions, no crossovers, etc.
