Control Electronics parts diagram. Numbers match the table below; each box is one top-level part or assembly with what it contains.
#PartQtyWhat it does
1 Train Control Computer 4 parts 1× Vehicle control computer coordinating traction, braking and auxiliaries over the train bus.
2 ETCS Onboard Unit 4 parts 1× European Train Control System computer reading balises and enforcing the movement authority.
3 Driver Display 3 parts 2× Driver-machine interface combining the ETCS speed display and TCMS diagnostics.
4 Wire Bundle 6× Group of insulated conductors cut to length, terminated, and bound together to carry power and signals between the assemblies of a machine.
5 Connector 80× Mating plug-and-socket pair that joins two lengths of wiring or a cable to a board so a circuit can be assembled, serviced, and separated without soldering.
6 Relay 30× Electromechanical switch in which a small coil current closes or opens contacts rated for a much larger load, isolating control circuits from what they switch.
