This is my rewrite of a chart I made about 10 years ago (using Protovis, the predecessor to D3), hence the old data. Back then there were no baby bullets on weekends!

If someone wants to collect the new data and send me a suggestion I’d be happy to update the chart.
- inferiorhuman 7y agoWhat did you use as the original data source? I've been poking at some GTFS data but there seems to be no obvious way to get distance traveled between stations (aside from as-the-crow-flies).
- mbostock 7y agoGood question. The times were published on Caltrain’s website, but I don’t recall where we got the distance data; it’s possible the initial implementation and data collection was done by collaborator, Vadim Ogievetsky. Wikipedia has track distances: https://en.wikipedia.org/wiki/List_of_Caltrain_stations https://en.wikipedia.org/wiki/List_of_Caltrain_stations
- inferiorhuman 7y agoAh. I was actually looking at making a similar plot of some other Bay Area transit agencies. Good to know about the Caltrain distances tho.
- supernova87a 7y agoExcellent, thanks for that!
