prakhar9642/RailSync ? reverse-engineered prompt

Build me a web app for railway maintenance block planning that helps coordinate Engineering, S&T, and TRD work without blocking train operations more than necessary.

I want a planning workspace where someone can pick a railway section and see available time windows, conflicts with train movements, and the best combined maintenance block. It should compare a simple baseline plan with a smarter integrated plan, explain why certain windows are usable or not, and show a clear summary of crew, machine, power isolation, and setup time limits.

Also include a scenario recovery view where a user can simulate delays, crew or machine unavailability, power isolation cancellation, weather issues, or an emergency job, then reoptimize with minimal changes to the existing plan.

Make it feel like a real prototype with a clean dashboard, plan review status, history, exports, and useful diagnostics. If needed, look up current docs online for React, FastAPI, and OR Tools.
