ERL Background Information

• The consortium led by Malaysian railway operator, Express Rail Link Sdn. Bhd. (ERL SB) and the Transportation Systems Group of Siemens AG have won the contract (announced 1998) to construct a complete rapid transit link between Kuala Lumpur’s main train station and the new Kuala Lumpur International Airport.

• Siemens supplied the telecommunication system including the radio system.

• Motorola was selected as the sub-supplier to provide the TETRA integrated digital radio system.


Why TETRA

• TETRA is selected as the radio technology for the following reasons:– Open Standards

• Guaranteed minimum performance.• Provides evolutionary growth.• Sourcing from more than one vendor.• Competitive pricing.

– Frequency Efficient.– Integrated voice and data.– Features that meet ERL’s requirements.

• TETRA will safeguard ERL’s investment for the next 10 to 15 years.

• The TETRA system is the first to be implemented in Malaysia.• The ERL TETRA system is the first operational TETRA system for Rail in

the world.– Award in May 2000– Operational in 19 April 2002


ERL Radio System

• The TETRA radio system was equipped with the following functions:

– Communications between Dispatchers and Train Drivers to be full-duplex individual calls.

– Calling of Trains by their assigned Train Run Number (TRN).

– Integrated voice and data call functionalities.

– Customized Screen for Dispatch Operators.

– Customized Radio Control Panel (RCP) for train drivers.

– Other interface include:• PA System

• The overall TETRA radio system was designed with high reliability and redundancy.


Selection of Radio Solution

• As TETRA was relatively new in implementation, thus the selection process was thorough and complete.

• The selection of TETRA radio solution for ERL was based on the following criteria, but not limited to:

– Well proven and accepted TETRA platform.– Have experiences in rail related projects.– Able to provide complete end-to-end radio communications solution for rail applications.– Ability to demonstrate working system with emphasis on rail applications.– System release that can meet the project schedule.– Strong local presence and support.– A radio supplier that understand rail operations and applications.


Proposed Radio Solution

• The TETRA solution is based on Motorola’s well proven and accepted Dimetra (TETRA-compliant) platform.

• The scope of supply included:– Central Network Equipment at Master Site – 7 x Radio Base Stations

• 380 – 400 MHz• 2 Base Radios per site

– 5 x Customized GUI Dispatchers– 24 x Trainborne Mobile Radios

• Mobile Radio, Train Control Interface, Radio Control Panel

– 20 x Vehicle Mobile Radios• Standard Mobile Radio installation

– 200 Portable Radio• Vehicular Adapter

Radio Dispatch Sub-system

• The radio dispatch application was customized according to ERL’s operational requirements.

• The development of application is based on Application Program Interfaces provided by the Motorola’s Dimetra system.

• All required functionalities are performed from the customized GUI of the dispatch terminals. Key functions include:

– Calling of trains by their assigned Train Run Number.– Full duplex private calls between Dispatcher and Train Drivers.– PA announcement to trains from Dispatcher at OCC.– Etc.

• Samples of the GUI display are as follows.





Trainborne Radio Sub-system

• The trainborne radio sub-system can be divided into the mobile radio, train control interface and the radio control panel.

• The trainborne radio application was customized according to ERL’s operational requirements. The development of application was again based on Application Program Interfaces provided by the Motorola’s Dimetra system.

• All required functionalities are performed from the radio control panel of the trainborne radio sub-system. Key functions will include:

– Full duplex private calls between Train Drivers and Dispatcher.– Sending of data status, e.g. Request-To-Talk (RTT).– Integration to train PA system.

• Samples of the trainborne control interface and radio control panel are as follow.

Benefits

• Consistent audio quality across the entire 57km of the KLIA line.• Coverage at and between stations.• Provision of reliable information about train operations, engine

health and track maintenance.• Increased productivity through instant maintenance requests.• Improved customer service with notification of hindrances to

passenger comfort and safety.


Conclusions

• TETRA communication system has been implemented successfully

• The signals are clear • The voice clarity is excellent


Conclusion

• The Motorola TETRA radio system effectively meets all of ERL’s operational and functional expectations.
