A track set with a roadbed that can configure both R195 and R220 track intervals. Oval outer dimensions are approximately 460mm x 900mm. Metal parts such as rails are made of white material (nickel silver) with excellent conductivity (some stainless steel). The joints that connect to the roadbed are a separate part that can be replaced immediately if it is damaged. The shape of the cross section of the metal rail is made with a special rail that is made with "E" shape. The straight rail has a power supply part, so you can supply several places to make the car speed uniformly. The power supply part comes with a cover, so if you do not want to power it, you can keep it on to prevent it from damaging its appearance.
