Each block is independent of all the others, so a train in block A can be operated by power pack A, and a train in block B can be run by power pack B.Įach block starts and ends with a plastic insulated rail joiner or a narrow gap cut through the metal rails. With cab-control wiring, a layout using two power packs is divided into several electrically isolated sections called “blocks.” One such block is shown in fig. With two direct- current power packs, single-pole double-throw toggle switches, and hardware-store wire, you can divide any layout into electrical blocks that will allow two trains to be operated independently. This milepost can be reached with cab-control wiring.
