What is this?

Service Bulletins

Service Bulletins are available on their own dedicated page. The data provided by PRT for bulletins may be inaccurate or missing.

The Data

System Map

How It Works

The Stack

This application is built using React with NextJS, NextUI and OpenLayers.

The backend stack is Fastify and converts responses from PRT into GeoJSON, allowing easy integration with multiple mapping libraries.
