Hi
If you are going to use the autoallocate feature of dispatcher then the use of
auto generated sections and transits can lead to failure in any situation
involving single track two way running, safe sections, crossings, slips etc. It
will work reliably only if you run one auto allocated train at a time. It will
work if you have no complex junctions or crossings on the route.
This is because most of the auto allocate conflict detection is predicated on a
block only being in one section, that is there is only one section for a given
section of track which is reused in transits regardless of direction or
destination. Generation of auto allocated section creates sections,
unnecessarily, in both directions, or overlaps sections. Because it creates
sections from mast to mast it inevitably creates sections that start with as
switch followed by a block. This will lock the switch until that block attached
is cleared, this sometimes leads to a deadlock when 2 trains meet on a single
track line at a passing siding.

Tim,
SML is signal mast logic.
I always use automatic discovery. I then test using simulated occupancy
sensors and manual turnout settings to verify that the logic is correct. The
most likely failures are caused by double cross-overs.
On your layout, I deleted the existing transit, sections and SML. I also used
the Block table "Paths >> Delete Paths¡" option. I then saved the panel xml
file, stopped and re-started PanelPro. After a lot of changes, the block
routing can get out of whack. This creates a new set of block routes, which
is the basis for SML.
I then used the signal mast logic table to generate the signal mast logic and
the sections. The section generation also creates the direction sensors for
each section.
After those steps were done, I created a transit, a train and ran it around
the layout using occupancy sensor buttons on the panel.

Hi Dave,
Thanks for this, to be honest i thought i had gone through that process of
getting each section right but its a bit of a steep learning curve, been at
this for all of a week now!
I will look at the block assignment when i get back home, when you talk
about the SML (assume this is signal mas logic) is the best way to let JRMI
auto generate all of the logic or is human intervention better?
Many thanks for your time
Tim
