Forum - GBC Train From The Great Ball Contraption Wiki Special page Tools Special pages Printable version Overview > Great Ball Contraption > Customs > GBC Train Write a reply [#34] Here's a link to the original GBC train we used at Brickfest '05 http://www.teamhassenplug.org/GBC/Train/ In that GBC, we had a train track running behind the entire contraption, which was split into four separate sections. We could bypass any section with the trains (we had two running) and keep the rest of the layout running at full speed. Steve Posted by Hassenplug on 7 July 2015 at 19:56.
