COAT on-board equipment – making sure the train understands the rails.

In terms of on-board equipment, modernisation and the requisite updates are also constantly accelerating. One aim of smartrail 4.0 is to introduce new features to vehicles quickly and easily. This reduces complexity and increases the standardisation of vehicle architectures. 

New technologies also introduce higher levels of automation to the railway sector, powerful functions, low per-function development costs and the possibility of rapid change and further development. At the same time, these technologies also introduce high levels of networking and thus more and more compatible relationships, rapid growth in the number of functions and short life cycles – in sum, the inevitable result is variety and dynamism.

Within the framework of the smartrail 4.0 program, many functionalities can also be implemented on the vehicle side: These range from ETCS Level 3 and the FRMCS data transmission system to precise and safe localisation. The aim is to achieve a standardised European architecture with defined interfaces and the separation of hardware from software.

This approach has great potential. The standardisation of generic vehicle equipment and vehicle interfaces can simplify architecture, reduce component diversity and reduce the effort involved in integration and authorisation. This greatly simplifies the upgradability and thus also reduces follow-up operating costs. In addition, a standardised, open system ensures better reliability and availability through greater transparency and more unified components. An open standardised platform is a fundamental enabler for the introduction of new, train safety functions in rail vehicles in the future.
