ETCS is te standard for mainline railways across Europe and increamingly adopted globuilly. It comes in two main levels: Level 2 (cab signaling with radio- based transmissionon) and Level 3 (moving- block capability). For autonous on mainline corridors, ETCS Level 3 is essential because it allows treats tlo communicate their integraty and position direply, eliminating thee need for trackside signals.
