This app is comprised of:

• a script to fetch the schedule for trains between two Transilien train stations and notify you when a train is canceled
• a webapp to display and analyze schedules and schedules' history

The app uses the Transilien Live API described here: https://ressources.data.sncf.com/explore/dataset/api-temps-reel-transilien/. You must apply for (free) access to the API.

virtualenv -p python3 pyenv   # python3 required
. pyenv/bin/activate
pip install -r requirements.txt

First, copy the config file settings.py.sample to settings.py and edit to your liking. Required parameters are:

• FROM_STATION_CODE: the departure train station code you want to monitor
• TO_STATION_CODE: the arrival train station code you want to monitor
• TRANSILIEN_API_LOGIN and TRANSILIEN_API_PWD: credentials for the Transilien API

You can enable mail and Pushbullet notifications for canceled trains, which require additionnal parameters.

Then you need to gather some data:

. pyenv/bin/activate
python flag.py

You should run this script regularly as a cron, a 5 mins interval seems good enough.

Finally you can launch the web interface:

. pyenv/bin/activate
python web.py
# visit http://localhost:5000

1. Run the API webserver as above
2. Run the frontend in dev mode:

cd frontend
nvm install && nvm use
npm i
npm run dev
# visit http://localhost:8080

cd frontend && nvm use && npm run build

Flask will render the dist/index.html on /.
