13.4.7 Decision Support System (DSS):

(a) Based on the constraints & logic given by Railways, system will give
optimized decision to admit or dispatch particular train at entry/exit points of
a particular section.

(b) Train running at the time of disruption: System will suggest effect of
disruption on train service. Based on constraints, facilities & logic provided
by railways, system will give solution for running of trains, diversion,
cancellation or regulation of train services.

(c) System will be able to detect conflicts like:

(i) Usage of the same platform;

(ii) Usage of the same routes;

(iii) Usage of incompatible routes;

(iv) Usage of the same section and same directions;

(v) Usage of the same section and opposite directions.

(d) In case of conflicts, TMS display a specific icon on the train graph and
generates a solution which consists in the rescheduling of the involved
activities.

13.4.8 Various TMS Terminals may be provided, as required, as under:

(a) TMS Terminal for Signal Fault Controller at OCC: Remote monitoring of
status of signalling equipment at stations and in Block Sections will be
provided on these terminals. This will include logging in of events in central
system, generating alarms, alerts etc. Signalling equipment failure alarms
as decided by the Engineer along with category will be available on the
terminal. It will be possible to acknowledge the alarms by the user.

(b) TMS Terminals for Track Controller and Traction Power Controller at
OCC: Equipment failure alarms specific to Track or Traction Power, as
decided by the Engineer along with category will be available on the
respective terminals. It will be possible to input remarks/Information pertaining
to various unusual occurrences e.g. failures & delays to operation etc.

(c) TMS Maintenance Terminal at OCC: The Maintenance Terminal will be
used for supervisory functions of the network and for observing any
required nodes and their configuration at any time. Displays of equipment
faults, communication failure occurring anywhere in the OCC or field
network will be available. Failure alarms will also be given.

It will be possible to bypass any node if so required and configure other
terminals from this terminal.
