A global rail vehicle manufacturer (OEM) required a fixed-price solution to couple an old and a new variant of its regional train model with minimum retrofitting so they could communicate with each other. Expleo created a smart new coupling system to allow the different generations of trains to be used together, offering more flexibility for operators.


Discover how our team created an innovative solution that required little change of the existing infrastructure and limited costs: a software for a black-box device that translates bus communication from new to old, and vice versa.


Value-adding practical and customised solutions

The Mixed Mode Operation System (MXT) function is a unique selling point and market advantage for both the client and transport operators. Expleo’s dedicated solution obtained approval from the TÜV, a renowned German testing and certification authority.

Our idea was to add a specific device to the train’s bus but in such a clever way that it could do all the translation, without the need to change anything of the existing design.
