Agree. One can see this with the geometric influence on some layouts constrained by train set track packs and set track products. Rectangular loop layouts with 1st radius short points. Such really constrains the ability to model prototypical realism. However its probably where most of us started, a hornby transit, buying an few track packs to add, growing the train set layout under the bed or on the bedroom floor, suited manufacturers back then as the demand for track accessory packs was high, but nowadays, its grown up kids reconstructing childhood nostalgia, and a great way to keep grand children away from iPads and smartphones for entertainment. Constructing track layouts from setrack packs was akin to building things with Meccano, thought resourcefulness, basic engineering skills and let imagination loose. Happy days they were. I remember the beano and dandy hardback annuals were welcome Christmas presents as they made perfect height platforms.
