Luggage Service from Lucern to Zermatt

SBB will show you the fastest connections, but you don't need to take them. You can take any train along the way, so if you miss one, there will be another train along relatively soon. You can also see the alternate trains at www.sbb.ch/en, by clicking on the "advanced search" button, then scroll down and specify a longer connection time. If you choose a minimum 10 minute connection time. You'll see departures on the even hours from Luzern (like 8:00 am, 10:00 am, etc) giving a 34 minute connection at Bern from Track 3 to Track 6, then an 11 minute connection at Visp from Track 7 to Track 3. If you missed that one, there is another train to Zermatt in 27 minutes. I think I'd opt for that rather than paying big bucks for express luggage service.

Yes, you can send your luggage ahead to Zermatt and then pick it up at the station when you arrive. However, you must send it early so that it will be there when you arrive...early as in a day or two ahead. The luggage transfer service has changed, but we've used it in the past with great success.

As you've found, the only same-day delivery service option now is the Door-to-Door Express version. The Swiss Railways are very organized. I experienced the service when traveling with a group and would trust them at least as much as any UPS or FedEx here at home. It's obviously a better value for larger groups than small ones. You pay the two lump-sum fees plus the fee per bag:

Flat rate door to door charge: 40

Flat rate for express shipping: 30

Luggage item: 12 x number of bags (x 4 = 48)

Total of 118 CHF for 4 bags, or 142 for 6 bags, etc.
