<\/a>Nodes 4 and 5 are physically adjacent and share track between them. We’ll be programming signals for the Main line; diverging tracks are for sidings, team tracks or a small yard. <\/p>\n\n\n\n
Before configuring signals, nodes 04 and 05 have to be configured to selectively listen for each other’s objects (See Blocks <\/a>and Turnouts<\/a>), as shown below:<\/p>\n\n\n\n This signal faces east and controls west-bound traffic on the mainline from Node 04, Turnout 0 to Node 05, Turnout 4. Here is one way to configure the signal:<\/p>\n\n\n\n In this case, the state of the signal depends on local block 0 and local turnout 0, plus two blocks and two turnouts on adjacent node 05 that this node monitors. Further, not all conditions require a STOP aspect; two remote conditions are deemed far enough away to justify APPROACH instead. <\/p>\n\n\n\n When interpreting these settings, keep two automatic rules in mind:<\/p>\n\n\n\n So, the rule for S0, Node 04, would look like this written out:<\/p>\n\n\n\n S1 faces west protects Turnout 0 only, so here we’re creating a STOP\/OFF signal. You would likely use additional signals in this area to convey additional information beyond the turnout.<\/p>\n\n\n\n The resulting rule:<\/p>\n\n\n\n This signal faces west and controls east-bound traffic from Node 05, Turnout 4 to Node 04, turnout 0.<\/p>\n\n\n\n The resulting rule:<\/p>\n\n\n\n This signal faces east and controls east-bound traffic through the interchange from Turnout 5 through Turnout 4 to Block 2. We want to the signal to warn if Turnout 4 is lined for the divergent route since that leads to team tracks or if Block 2 is occupied. For both conditions we want S1 to show APPROACH.<\/p>\n\n\n\n The resulting rule:<\/p>\n\n\n\n In this situation, you could set the aspect if Block 2 is occupied to STOP. However, because STOP conditions take priority, any occupancy of Block 2 would force STOP at S1 even when Turnout 4 is lined for the divergent route. Instead, the best approach in a situation like this is to limit S1’s primary responsibility to the T5 -> T4 section, and assume an additional downstream signal to fully cover Block 2.<\/p>\n\n\n\n Of course, using multiple signal heads (each head is a logical signal) is another way to handle complex intersections.<\/p>\n","protected":false},"excerpt":{"rendered":" Lets use the Signal Manager to define multiple signals on two nodes.
