what does day mean?

  1. Awesome dataset, thanks for putting this online!
  2. What does day in the schedules table mean? I see it goes from 1 to 13 so it's probably not day of the week as I first assumed 😁

Hey @masalmon glad you find the dataset useful :-)

So, day in the schedules table means the day of the journey - i.e. day 1 7pm would be 7pm on the first day of the journey, day 4 7pm would be 7pm on the 4th day of the journey, and so forth. Does that make sense?

Day 13 does sound a bit extreme though, didn't know there were any trains with 13 day long journeys :( - that could be an error in the data, will take a look, but it could also be a really long train that I don't know about :-)

Anyway, please do also let know if you notice weird things with the data as you work with it - it's not perfect and could use all the eyes we can get on it to improve it. Thanks!

Thanks @batpad ! I now understand day. So schedules doesn't tell how often a train circulates, right?

I'll definitely keep opening issues if needed but really this is a very cool dataset. 😸

Another question I have is which time zone was used for defining the arrival and departure times? Is it e.g. always "Asia/Kolkata"? Thanks in advance.

This information should have been contained in trains.json, but looking at it now, I can't see it :-( - let me look at some of our data processing scripts and see if we can rescue this data, or refresh my memory on this a bit - thanks so much for the catch here. cc @geohacker

Is it e.g. always "Asia/Kolkata"

Yes, it is always +0530 UTC, i.e. Asia/Kolkata.
