As railways moved have moved on so has activity within a station.
Traffic today is simply train in, train out and apart from some splitting no actual shunting.
Any station using DMUs/ EMUs would have been like this for many years with only any residual parcels traffic remaining to shunt declining as traffic declined.
I quickly realised this when I bought some EMUs - they simply slid in and out of the station, nothing much else to do with them unless I stuck in a carriage siding so that some units could shunt out of the way whilst another unit arrived/departed.
Typically with model railways we engineer problems or unnecessary extra moves to generate interest because that in reality it wouldn't be there on a railway. When I was a spotter I used to go to Manchester Victoria - it had more interesting moves than Piccadilly which mainly involved DMUs and EMUs in and out, most of the parcels traffic was out at Mayfield and the electric trains didn't tend to be shunted, a new loco was simply attached at the front.
Bradfield offered nice shunting puzzles which made it interesting to watch, it was probably also convoluted by design to make it more interesting but at least back then there was a lot more going on in a station than a similar station in the 1970s and in the case of Bradfield it was well executed.
