In accordance with the ERTMS/ETCS specifications, Subset 121, UIC 612 leaflet, ERA ERTMS-015560 3.3.0
document, EN 50126 and EN 61375 series requirements, this Technical Report describes the Train Display
System (TDS) in the driver’s cab, and the link between the TDS/TDC and some of its interfaces.The scope of the Train Display System (TDS) thus includes:
a) Functions, except functions defined in the ETCS Subset 121. These functions describe exchanges between
TDC and the connected display systems;
b) Performance allocation (RAMS included as per EN 50126): for each function defined in item a), defining the
performances needed and the degraded modes recovering;
c) Needs for certification: description of special requirements to avoid ETCS recertification after other display
system modification;
d) Train Display Controller (TDC):
• Redundancy management;
• Architecture;
e) For each system connected (except those defined in ETCS Subset 121): the Functional Interface
Specification (FIS).
This Technical Report excludes the following items:
• Communication protocols (e.g. EN 61375 series);
• Ergonomic aspects;
• Interface with ETCS (Subset 121);
• Train functions;
• GSMR EIRENE functions;
• Use of the displays as terminals for maintenance purpose
