Introduction
Stockholm is a major city in Northern Europe and a port at the Baltic Sea. Like other Scandinavian capitals, it has a well developed transportation network. The coastal position of Stockholm means there are ferries connecting it to other ports of the Baltic. There are also local ferry lines. Add to that bus, train and subway lines and you get a better perspective of how large and complex the transit network of Sweden’s capital is.
Parts of the network
This article is the first in a series. Based on the available information, I intend to cover the following:
Obviously, the information will be presented if and only if there is open data about the respective line or group of lines. I hope that you will better understand the place where some of the the characters of the Millennium book series live.
The agency
The local transit network is operated by Storstockholms Lokaltrafik, known better as SL. This is by far the largest agency in the country. The website is in Swedish, so unless you speak the language it is quite hard to navigate. Google Translate could help, but be mindful.
Open Data
Like other Swedish towns, there is no official GTFS file to download. So, on this side, the information of the articles, while being as close as possible to the real world, there will always be some minor differences.
There is a data API, if you register on national data provider’s site. The number of tests I run in order to generate the PDF files would not be possible by using the API. That means that much of the information comes from Transit Feeds. Naturally, I crossed whenever possible that data with the official site.
Mobile Apps
There are SL apps for both Android and iOS. I can’t say much of the latter, as I have completely left the Apple world (any possible device) a few days ago, but I intend to test the former.
