scope:

The scope of this Technical Report is to define the ERTMS DMI in STM mode for each system include in Annex B of STI CC. This Technical Report defines the ergonomics for the Specific Transmission Module integrated in the Driver-Machine Interface (DMI) for the ERTMS/ETCS Train Control System, and for the integrated ERTMS/GSM-R Train Control and Train Radio Systems. The ergonomics covers the - general arrangements (dialogue structure, sequences, layout philosophy, colour philosophy), - symbols, - audible information, and - data entry arrangements. The reasons for defining the ergonomics of the DMI are as follows: 1. Achieving harmonised and coherent presentation for ERTMS/ETCS and STM information. Given the large number of STM.s requiring the use the ERTMS/ETCS DMI, only a harmonised approach is feasible. 2. Defining Driver-Machine Interface ergonomics that is compatible with agreed interoperable ERTMS specifications. 3. To reduce the risk of incorrect operation by a driver working with different trains fitted with ERTMS/ETCS. 4. Facilitating train operation with a unified ergonomics, hence reducing the cost of driver training. This Technical Report is applicable on all trains fitted with the ERTMS/ETCS.
