The E-Unit Cycler can also be used to automate track switches on any layout.

Three-Rail Innovation's E-Unit Cycler provides "Reverse" and "Station-Stop" operation of trolleys and engines that have E-Unit forward-neutral-reverse capability. Additional features are available for extending a back-and-forth layout with track switches, crossovers, and loops, all providing automatic operation. An optional "station time" wait can be configured for between 0 and 28 seconds.

Three-Rail Innovation's E-Unit Cycler provides track power cycling for operating E-Units, provision for controlling the cycling to "Skip," "Enable," or "Hold" a train, and capabilities for automatically operating track switches.

The EUC has three isolated outside-rail inputs and two double- throw relays. Inputs can be connected to isolated track sections, operator push buttons or switches, or EUC relays.

The EUC relay contacts are wired to track power to control trains or to track switches for providing automatic operation.

Three-Rail Innovation's E-Unit Cycler has features expressly designed for operating an automatic back-and-forth train layout:

• Each E-Unit Cycler has two independent cyclers.
• Cyclers may be configured for "Reverse" (stop, wait, then go back) or "Station" (stop, wait, continue) operation.
• Station "Wait" time selectable from 0 to 28 seconds.
• Station "Skip" control allows train routing variety.
• Station "Enable" and "Hold" controls allow train routing variety and multiple train operation.
• Routing variety can be wired for control manually by a "dispatcher" or automatically using Three-Rail's timing controllers.
• An arbitration controller is available for crossovers in a multiple train layout.
• Any type of track switch can be automatically operated.
• Track switches can be operated automatically in "Alternating," "50-50 Random," "Always Same Route," or "1-2 Route Opposite Last 2-1 Route" modes.

Start with one E-Unit Cycler to add a back-and-forth line to your layout. Then get more EUCs to extend the line with track switches and multiple train operation.

The E-Unit Cycler provides features for building back-and-forth train layouts from a simple length of track with reversing stops with station waits at each track-end to an automatic multi-train line with numerous reverse stops, station stops, track switches, and crossovers.

The E-Unit Cycler comes with a complete instruction manual. It shows how to fully utilize the EUC to implement everything from a simple back-and-forth line to an extensive back-and-forth layout with multiple trains running over track switches and crossovers.

Even if your wiring experience is limited, the operator manual will show you how to construct isolated outside-rail track blocks, connect them to EUC inputs, and to connect EUC power relays to control track power.
