Modular General Purpose Platform for Mobile Office IT Applications Modern trains are equipped with increasingly complex embedded systems to run and monitor onboard equipment, enhance passenger comfort, and deliver new functions. Not only does each independent application have its own hardware, but many also require a unique operating system and application software. This means railway management must deal with a host of different suppliers as well as communication and interoperability issues between systems or obsolescence problems. menRDC is the one mobile office IT computer system for virtually all non-vital train applications.

menRDC – MEN Railway Data Center
Modular General Purpose Platform for
Mobile Office IT Applications

2. 2
The Need for a Railway Data Center
Increasing demand for highly performant solutions
 More data
 More throughput
 More connectivity (IoT)
 High reliability, security, safety
Current situation and problems
 Many different systems for single functions
 Many different suppliers
 Few standards, huge variety, limited interoperability

3. 3
The menRDC Approach
menRDC is an open family concept
 Offering all relevant components for the complete IT infrastructure in a train
 Supporting virtualization to abstract application from hardware and consolidate
multiple applications in fewer systems
 Providing independency from single suppliers and obsolescence issues

4. 4
