Before you ask, this IS TurboJUK, creator of the Trouble With Trains series.
Okay, I'll primarily be hosting my Lego trains made in Lego Digital Designer (screenshot and actual locos). They may not be very realistic, but that's the idea. I design my locomotives with playability in mind; the influence of Lego's designs was profound. I make my models using only pieces available from LDD so people can buy them for themselves. All of my loco pages have the original files downloadable so you can buy the models for yourself.
