The Interlocking (IL) simulator of the ADR-029 sim trio — grants/extends Movement Authority by setting routes (ROUTE_ADD) against the RBC's wire protocol, built on SimCore's shared transport plumbing. Send-only in the reference scenario. One instance per train slot.

Driven by safeAPIRBC2oo2TestEnv/robot/ over SimCore's control port.

What's here

src/il/il_sim.py — the simulator, console script il-sim (il.il_sim:main).
src/il/message_catalog.json — this sim's own message-name/kind-number/field catalog.
src/il/site_data.py, src/il/il_wire.py — track-layout and IL-domain wire helpers.

Building

python -m build --outdir dist

Depends on simcore, resolved from SimCore/dist/ or Conan — see SimCore's README.

Running

pip install --find-links ../SimCore/dist --find-links dist ilrbcsim

il-sim # reads config from SIM_CONFIG_PATH, default /app/config.json

Dockerfile (context: the SAPI workspace root) builds a multi-stage image the same way TrainRBCSim's does. Normally run as part of the full stack via safeAPIRBC2oo2TestEnv/docker-compose.yml.
