Railway Construction Status Quo
Busy trunk line Regional branch lineRegional trunk line
Status quo:
Electrified passenger and
freight lines have encountered
speed upgrade bottlenecks,
leading to insufficient transport
capacity.
Construction:
1) building dedicated high-
speed passenger lines (E1/E2)
2) reconstructing heavy-haul
freight lines (20,000 tons)
Status quo:
Few mixed passenger and freight
lines, non-electrified, primarily
single-line, outdated facilities,
and little transport requirements
in most regions.
Construction:
1) improving transport capacity of
legacy lines
2) building mixed low-cost
passenger and freight transport
lines (ERTMS-Regional))
Status quo: mixed passenger and
freight lines (some are non-
electrified lines with a speed
lower than 120 km/h),
insufficient transport capacity.
Construction:
1) improving transport capacity
of legacy lines
2) building mixed passenger
and freight lines (E1/E2)

Key Design 1.2: 1+1 Transmission and Ring Network Protection, Multi-ring
Access, Reliable Bearing
1. The access layer uses sideway optical cables to
enable SNCP/MSP ring network protection.
2. Nodes form multiple ring networks (each
network has 4-6 nodes, not more than 8 nodes),
avoiding signal deterioration.
3. Backbone layer nodes use sideway optical
cables to enable linear 1+1 multiplex section
protection.
4. Shared optical multiplex section protection is
established for large neighboring stations.
Use service-, device-, and network-level protection
methods to ensure high railway service reliability
and security.

From 2001, Russian TransTeleCom was planning to construct a DWDM national railway
backbone communication network that spans Europe and Asia.
An ultra-long-haul (total length: 18,713 kilometers) service transmission network is
required. Long-distance transmission and signal attenuation pose higher requirements on
transmission devices.
Russian TransTeleCo constructed a secure and table high-speed long-distance
transmission system that spans Europe and Asia. Vendors that pose requirements on
service transmission between Europe and Asia compete for leasing network bandwidth,
which helps customers quickly recoup capital outlay and obtain profitable returns.
The powerful network management system provides quick service deployment capabilities,
facilitating new service rollout and reducing over 30% network construction and O&M
costs.
Deploys OptiX BWS 1600G and advanced Super WDM technology to build a long-distance
transmission network.
Provides high power booster amplifier (HBA) and Raman technology to implement ultra

• The FAS system is used for
dispatching communication (including
train dispatching, power dispatching,
cargo dispatching, and maintenance
dispatching) between the OCC and
stations along the railway.
• The FAS system is mainly comprised
of dispatch switches, dispatch
consoles, and station consoles.
• Partner: Jiaxun Feihong
Solution Description
• High reliability and dual-backup
mechanism, ensuring that dispatching
communication is available at any
time
• Easy maintenance and convenient
service upgrade

• Trackside phones, deployed in sections,
are mainly used for voice communication
between maintenance personnel and on-
duty personnel in stations.
• HPs, deployed at station platforms and
key section regions such as tunnels and
bridges, are used by passengers and
work staff to make emergency calls with
on-duty personnel in the stations or OCC
in case of emergencies.
• Partner: Shanghai Shengtong and Hong
Kong KOONTECH
Solution Description
• Applies to harsh environments and
ensures high-reliability communication.
• Ensures proper service operation.

The PIS system provides passengers
with travel guide information, including
train information, bulletins, news, and
advertisements and provides dynamic
evacuation guidance for passengers in
case of emergencies.
Hierarchical and layered management is
supported. When a lower-level server is
faulty, the upper-level server takes over
services from the lower-level server.
The local degraded mode is supported.
When the upper-level server is faulty or
disconnected, the local server takes
over services from the upper-level
server.
Solution Description
• High reliability to ensure secure and
efficient operation
• Hierarchical management to simplify
O&M
• Multimedia advertisements to increase
revenue
