I have a simple 3 train yard connected to another block with several turnouts as below

My desire is to have a train leave the yard then run another transit continuously.

?

Since a continuous transit requires first/last section to be the same it seems this requires two transits. I thought I could create a transit to start in BY1 and end in Central then chain to the next transit.

?

My problem is with the leaving yard transit (which is terminate when done for testing). As soon as it allocates the Central section, the mast turns red/red and the train never moves. If I click the mast green the train moves and stops in Central as expected.

?

So, how can I make this to allow move train out automatically after allocation?

?

Steve,

I suspect that there is a SML issue when Dispatcher sets the turnouts. ?If you upload the xml file we take a closer look.

Dave,

Some additional information...

?

I know you advised making each block a separate section. I originally did that but couldn't understand how to create the direction sensors so I deleted and went back to auto-generated.

?

Auto-gen combines blocks based on my mast and there's no way to create a mast for the next block since it's attached to the turnout.

?

So I manually created a separate section with just Central block.

Steve,

Direction sensors are required for signal heads/SSL.

Direction sensors are optional for signal masts and SML. ?From my point of view, they are generally used to implement APB (absolute permissive block) signaling.

When you generate SML based sections, the SML and Section are related. ?Transits can start or end with a block based section (such as leaving a yard), but the other sections have to be SML based sections. ?This is why your block based section for Central causes the SML to display Stop when allocated. ?The "linkage" is missing.
