Block Control allows more than one train to run on the same track. The isolated outside-rail technique is used to know when a track "block" is clear and a block can be powered to move a train into the next block.

An Automated Layout controls track switches so trains take different routes, all without close operator attention.

Click the bars on this page to learn about block control, review automated layout track plans, and see how the Train Block Controller can automate your train layout.

An automated layout starts with the track being divided into "blocks." A train moves in one direction from one track block to a following track block.

Detailed track plans for automated layouts illustrate how the TBC is used for block control and can help with automated layout design. Track plans for automated layouts are described.

Three-Rail Innovations' "Train Block Controller" implements a block control system for your three-rail train layout.

The K 'N G Railplex is an example of a high-action train layout implemented with block control.
