A complete block signaling module for one block with an interlocked siding. Package includes the signals, train sensors, block detectors and all wiring. Available in simple to assemble kit form or pre-wired and ready to operate, just install it and hook up power (12 or 24 VDC). Use this module to connect block signaled mains to un-signaled side tracks or yard leads.

Detects trains entering and leaving the block with sealed magnetic sensors that you insert into your ties. Fully supports the included SL1/3 3 aspect searchlight signals to include the remote yellow aspect (train in adjacent block). The dwarf signal is interlocked and is also a block signal! Facing point SL1/3 will show yellow when the switch is set for the siding with no train in the block, trailing point SL1/3 will show red. Supports backing moves. Movement in/out of the siding is handled as block entry/exit traffic. All components are fully waterproof and designed for 24x7 operation. Includes two magnets (enough for one train).

The block is available in lengths of between 10 and 50 feet (select in options) and comes with a pre-wired backbone cable that interconnects all the components. All you have to do to install the RTR package is to mount the signals, press the train sensors into the inside of your tie, mount the track side relay box and connect up power. The package can run off track power (constant DC or DCC) or a separate DC supply. With the kit option you will connect signals, sensors and block detectors to the block common buss with solder less snap on connectors (included). All wiring is color coded and we include step by step instructions.

When configuring the module you need to specify block type (see the first thumbnail), length (Dim A) and length to dwarf signal location( Dim B). This module requires aux contacts on your switch machine, if you don't have aux contacts, use our optional magnetic turnout sensor. In the RTR version we wire the turnout sensor to be mounted on the curved side of the switch (top mount). If you need it on the straight side or you want a bottom mount, tell us that in special instructions when you order.

The module includes interconnects on both ends to allow you to connect it to any other IPTrains block signaling or interlocking module. Power may be shared between modules to simplify wiring. The diagram below shows the internal wiring of the module including train sensors, the block detector module and the signals. All of that wiring is done for you in the RTR version, the kit version takes about an hour to assemble.

Sensor options include our standard in tie train sensor or our highly sensitive bar double sensor.  The double bar sensor include both the red and the green sensor in one waterproof package and may be mounted on the ties to the right of the rail or below grade beneath the right rail.
