Train-to-ground communication networks
14
To provide the situational awareness to
operators in OCC of the train operations and
passengers on board.
▪ Live streaming of multiple CCTV feeds (via
WiFi);
▪ Passenger emergency voice calls (via
TETRA);
▪ Real-time data from train management
system.
The elements to enable this capability:
Train-borneAccess point controller, Antenna, Network switch, CCTV,
PEC, Speaker etc

Train-borne systems
15
Train-borne communication system
functions as a communication gateway
between on-board operational sub-
systems with train-to-ground
communication network.
At each car:
▪ CCTV cameras;
▪ Network Video Recorder (NVR);
▪ Passenger Emergency Call;
▪ Passenger Information Display;
▪ Public Address;
For high availability, both ends of the train
are installed with:
▪ WiFi AP controllers (dual-radio), incl.
network equipment;
▪ On-board TETRA system.

Two layers:
▪ TETRA is used for vital voice
communications;
▪ WiFi (IEEE 802.11) for wireless
broadband.
For wireless broadband:
▪ Coverage along the metro lines, including
station;
▪ Mobility capability whilst train moving at
100 kmph;
▪ Capacity performance of at least 25 Mbps;
▪ Seamless handover with packet loss
<0.1% at stop, 1% on the move;
▪ Fast roaming <30ms.
Coverage overlap is needed to ensure seamless
handover (roaming) and constant data
throughput.
© SAPURA GROUP STRICTLY PRIVATE & CONFIDENTIAL
The backbone transmission network:
▪ Fibre backbone for all uni- & bi-directional communication
paths between stations, depot, buildings, TPSS, BSS & OCC.
▪ Dense Wavelength Division Multiplexing (DWDM) technology.
▪ 20Gbits/s transmission rate, future upgradeable
▪ LAN with Layer 3 or Layer 2 networking nodes, with 3
QoS/traffic classes (i.e mission critical application)
The backbone also provides connectivity for other rail systems such
as Automatic Fare Collection (AFC), Electronic Access Control
System (EACS), Corporate IT system.
Backbone transmission network

Trackside network access points (NAP) are connected to the
backbone via access switches (LAN).

Station-level communication systems
18
At station-level, operator in station control room is able to:
▪ Monitor live streaming of multiple CCTV feeds;
▪ Broadcast live or pre-recorded messages;
▪ Communicate via voice and short messages;
▪ Communicate via telephony with OCC, other stations, help points, emergency phones etc.
The communication system plays a key role in managing situations pertaining to intrusion and fire:
▪ In case of fire: signalling is informed immediately to either bypass station or move the opposite direction.
▪ In case intrusion: Controller is alerted with a CCTV pop-up, and the public announcement & passenger display system are primed.

The brain of the whole metro operations, incl. depot in all scenarios:
▪ normal
▪ degraded
▪ emergency
Traffic management.
SCADA: all systems, inclu. M&E, LV systems, substations, distribution network.
Security management – surveillance, access.
Passenger information, inclu. public address.
Communications: TETRA, WiFi, Telephony, GIRN
Network management
In emergencies situation in tunnel (fire or trains topped), SCADA system plays a central role in
▪ alerting signalling;
▪ priming the public address & passenger information.

Voice & data communication capabilities for public safety agencies
20
GIRN system installed in underground sections provides public safety agencies with two-way inter & intra agency voice & data communication for day-to-day ops & during emergency.
Dual redundancy configuration (BSR, links, path, processors, physical connections) to ensure high reliability for mission critical operation needs.
RF distribution based on:
▪ DAS for in-building;
▪ leaky for tunnel; and
▪ RF BDA for short tunnel.

Concluding thoughts
23
No proper tools
processes
Gap in scope of work
“Grey Areas”
Unavailability of
Information from others
Proper tools and process of handling is not well defined.
Adherence to defined process
Demarcation of scope of works & responsibilities between
parties are not clear.
Complete definition of system is not always available.
Coordination!
Everybody is progressing at different rates.
