Rail Weather Electrical Backup Operations Package

Calculates source-bound rail weather and backup operations metrics from a deterministic SSC-17 task-owned source pack. The template combines signalling and communications loads, weather heating, battery/generator energy, thermal rating, sag, feeder voltage drop, and an overall synthetic pass score.

with-tool: The model is given an executable Python calculator script.

Difficulty

Each template is sampled at three tiers. Harder tiers may hide inputs, forcing the model to infer them from the scenario description.

All inputs remain visible at every tier

For this template, difficulty scales through parameter and scenario ranges rather than hidden information.

All source-pack values given for the SSC-17 rail weather backup operations package
medium:
