It's actually pretty strange, kids fall in love with trains as early as toddler years with play trains, but the passion for actually investing in constructing a high quality model train setup takes a real special person. I'm not that into it but I'm always at awe & I appreciate an excellent railway model setup.
I commend those guys who really do sculptural work to create a model of landscape & buildings then have their train & tracks go in various dirrections on the landscape to simulate a countryside along a train route.
