By developing TRainCom^®, one of the targets has been a flexible, modular and scalable system concept that allows its easy adaptation to various train networks and operational requirements. Today, in fact the basic system concept enables a very flexible design of the TRainCom^® system architecture. Also by adding further components to the system, a TRainCom radio system can be designed for:

• Part or full redundancy of central radio system components
• Full redundancy of the entire radio system
• Single or double channel radio capability with link aggregation
• Integration of multiple lines (e.g. up to 250 separate lines)
• Extended long lines
• Definable radio system availability
• Adaptation to available interfaces
• Integration of multiple data services/applications
• Definable high data transmission rates (up to 32 Mbps)
• Definable prioritization and bandwidth allocation mechanisms
• Integration of train components into radio system diagnostics
• Integration of radio diagnosis into overall diagnostic systems
• Integration of new data security mechanisms
• Remote maintenance capability
  

Operator advantages:

• IP-based systems – easy integration into existing system for re-design,
  or future sub-systems
• Upgradability to upcoming technical developments
• Modular – adaptable to network architecture

• Usage of COTS hardware components possible
• Use of common technologies
• Future growth potential
• No limitation in number of trains or metro lines
