Here are the SBB departure tables (the yellow SBB timetables at railways stations as PDFs) and network maps for SBB railway stations. If no result is shown for your chosen railway station and an error message appears despite correct spelling, this is because the railway station is operated by a different railway company (BLS, SOB, RhB etc.). The map you are looking for will be available on the website of the relevant railway company or regional transport network.
