MTA Subway Supplemental GTFS Feed

[Meira Zimble]

Hi, 

Is there documentation on best practices for loading and ingesting MTA Subway's Supplemental GTFS Feed?

Does the feed included planned and non planned service changes?

How far in advance on service changes loaded to the Feed?

According to MTA's developer page the feed is updated every hour, does the feed require an hourly loading to express current service or the hourly changes are for future changes?

We would like to understand how often to load the feed and what is the recommended schedule.

Thank you

The feed does not include unplanned service changes. It includes most planned service changes, but some (especially "simpler" ones that do not involve changing the terminals or service frequencies on a line) are not included.

They are loaded generally a few days out, usually not more than a week.

The hourly updates are for changes on subsequent days, the current day's schedule does not change once the day begins.
