Tom Lowa at 4DBrix has worked continuously to bring new innovations to the Lego train hobby for some time now. Using their own on-site 3D printer, they’ve been making things like remote switch mechanisms and modular switch tracks, as well as a lot of monorail components, if you’re into that kind of thing. More recently, however, there has been two new additions to the 4DBrix online store that really gives them some good reputation.
If you missed it or haven’t seen it yet, I don’t blame you. It hasn’t been “officially” announced by 4DBrix yet, but rest assured it IS listed on their site. Enter the “Ultimate Railroader” series. Aside from a clever name, this is 4DBrix’s play at getting into a more serious scale Lego railroading market. Currently, the only two products in this line are nearly the same, but different enough to make someone want one of each (or more). Tom has listed R148 crossovers, in both right-hand single crossover and double crossover configurations, on his website. He was also kind enough to send us a set of the double crossover to review, which will be the main point of this article.
