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single-line, outdated facilities,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)

1. HLR: 1+1 backup ensures user data security.

2. Dual homing enables MSC Server signaling

redundancy; load balancing enables MGW voice

channel DR; and SGSN Pool/GGSN Pool enables

geographical redundancy and load balancing,

improving resource utilization.

3. BSC geographical redundancy (industry's unique

1+1 hot backup): When the active BSC is faulty,

the standby BSC takes over the BTS, ensuring the

normal network operation.

4. Carrier frequency backup and double coverage

improve reliability while addressing the frequency

resource insufficiency issue.

Enables all-NE redundancy from core network to

wireless network, protecting services from any NE

fault.

Builds a highly reliable GSM-R network to safeguard

railway operation and maintenance.

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

FAS

2B+D

• 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

Section HP

• 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
