Old Transport Websites Disappearing
Until recently, Madeira's public transport was delivered by various companies, each with their own separate branding, ticketing and websites.
This has now been reorganised under the ambit of SIGA - the public transport organistation for Madeira. However, although many buses (and some transport passes) changed on 1st July, the SIGA website (and the mobile app) were missing much of the vital information and it was still necessary to rely on the former websites of the individual operators for timetable and fare information.
Those websites are now starting to disappear. The former EACL website now redirects to SIGA, the homepage of the SAM website still exists, but most of its pages now give 404 errors. The Rodoeste website still seems to be functioning, as is that for Horários do Funchal.
Unfortunately, the SIGA website is still sorely lacking in functionality - the "journey planner" doesn't work at all and if you select "Timetables" you have to select a "Municipality" - which is the municipality in which the bus route ends, not the municipality in which you wish to disembark. So, for example, if you select "Ribeira Brava", you'll just get the bus routes that end their journey in that municipality and the routes that go through Ribeira Brava to more distant locations (like Porto Moniz) won't show up at all. If you're intending to travel in the west and north of the island, you'll presently get more useful information from the Rodoeste website -as long as it continues to exist.
The Getting Around page will be periodically updated as the situation changes, but it has a habit of changing with little warning...
