This is a simple script which generates and updates a Google Calendar with the planned L Train service changes. The script uses the MTA API's Service Alert Feed to get the planned service changes and the Google Calendar API to update the calendar.
Calendar can be viewed here and instructions to add it to your own Google Calendar can be found here
This runs in an AWS Lambda function based on the dockerfile in the repo. The function is triggered by a CloudWatch event rule which runs every 6 hours. The function checks the MTA API for planned service changes and updates the Google Calendar accordingly.
