The number of trains you want to run determines the number of Automatic
Signal Blocks you need. You always need one more block than the
number of trains you want to run. In this example, we want to run two
trains, and so, we need three blocks.
The block circuits are very similar to the Semi-Automatic Signal Block.
As before, the circuit uses one 17100 for automatic "Stop" (Hp0) control.
However, there is no 51750 for manual "Go" (Hp1) control. Instead, there
is an additional 17100.
Here's the trick: The "Stop" 17100 is installed after the exit of the block,
just like before, but the "Go" 17100 is installed near the entrance of the
block two blocks ahead.
When a train leaves a block it disconnects power from the block immediately
behind it. When that train reaches the entrance of the next block, it
connects power to the block two blocks ahead, releasing the train stopped
in that block. This arrangement keeps the trains moving from block to
block, with one "Stop" block between them at all times.
This circuit is relatively simple to build, impressive to watch and easy to
operate. The only special consideration is that the distances between the
blocks should be at least one train length.
