Brand new Atlas 072 Switch.....sparking when Atlas engine passes over it. (My only Atlas engine). Apparently the engine causes a short as the roller and the wheel touch the "non movable rail at the same time......see picture. Cure is simple - take a single edge razor blade and drive it between the two rails as shown in picture. It only takes a "gentle touch" to provide just enough distance where the two rails don't touch. Problem solved.
