The TTC Venus innovates the traditional switch design. Their railings on extended from the usual 5.2mm to 6.0mm. TTC compares their extended rail design with how a high-speed railway is smoother because it has a seamless connection. In contrast, ordinary trains (or traditional switch designs) would have gaps in-between the rails which causes vibrations. Therefore, TTC made a switch with extended rails that make constant contact with railings that are on the top housing instead of the bottom housing on traditional switches. Due to this new railing design, the TTC Venus feel incredibly smooth and sound incredibly clean.
