The turntable is designed to operate with the Standard Train Controller R965. Drive the locomotive onto the turntable, then switch the power from track to turntable via the 'on-on' lever switch R046 (supplied with the set).Your speed controller now controls the rotation of the turntable. If you are using an HM2000 controller, then the turntable must be powered from the uncontrolled DC output with an R047 Lever Switch, 'on-off', not from the speed controller output.The set includes eight access track sections and wiring. You can add and subtract access sections to suit your layout, up to a maximum of fourteen.
