TrainController Gold and Silver - Freiwald Software

indicated as occupied when the train reaches “Southtown” release of “Main Line East”
is further delayed until the occupancy indication of “Main Line East” is turned off.
In detail the following rules apply:
• A block is assumed to be reached, when the train reaches a stop indicator assigned
to this block.
• An occupied block or route is not released. (An exception of this rule is outlined below.)
• A block or route is not released until the train has reached a block behind of this
block/route.
• When a train reaches a block all non-occupied blocks/routes located before this
block, but not located behind another occupied and reserved block/route, are released.
If, for example, “Main Line East” in Diagram 118 is still reserved and occupied
when the train reaches “Main Line West”, then the used block of “Southtown”
is not released, regardless whether it is occupied or not. If both, “Main Line East”
and the related block in “Southtown”, are unoccupied when the train reaches “Main
Line West”, then both blocks are released.
• When the train reaches the destination position of the current schedule, i.e. the stop
indicator in a destination block of this schedule, then all blocks and routes apart
from this last block are released, regardless whether they are currently occupied or
not.

Preset Block Signals and Speed Limits
As outlined in section 5.9, “Block Signals” TrainController automatically calculates
signal aspects for all trains running under control of the Dispatcher. These signal aspects
take into account the availability of blocks and routes ahead of the train. If the
train must not enter a block, then the signal of the previous block is set to “red”. If the
train can enter the block, then the signal is usually set to “green”. It is additionally possible,
however, to cause TrainController to display “yellow” instead of “green”, if
desired.
For this purpose it is possible to select an individual signal aspect (yellow or green) for
each block or each route in a schedule. Dependent on this setting TrainController
will automatically apply the selected color to the calculated block signal, if the train
may proceed.
These signal settings are specified at the level of blocks and routes in a schedule. That
means: the same block or route may have differing signal settings in different schedules.
