A little service that fetches iCalendar files from the "Wise Time Table".
The "Wise Time Table" serves the iCalendar files in an disingenuous way. They open a new page, redirect to a different URL and return the content as application/octet-stream, so the calendar cannot be consumed by other applications (only imported).
This service downloads the iCalendar file on request and serves it as text/plain.
The service is live at http://calendar.brokenpylons.com (this link redirects here). You can request the calendar file by calling the calendar endpoint. It accepts a parameter filterId, which you can get by navigating to the timetable website, selecting the options you want and then clicking the little book icon at the upper left corner. You will get a permanent link, then you just need to copy the filterId part.
For example:
http://calendar.brokenpylons.com/calendar?filterId=0;1;0;0;
This URL can be added to Google Calendar, Tunderbird, etc.
