Conventional DC Operations

Multiple Train Control Using Conventional Blocking

With conventional blocking, train operation depends on track wiring which can be extremely complex. Each block is powered and wired separately to allow more than one train to move around the layout. Trains move one block at a time by using insulated blocks and toggle switches to control power routing. This requires a lot of time and expense to wire and debug before you are up and running. Once you have it wired, you have to learn to "play the piano" and remember the rules to keep the trains moving.
