Milano - Interlaken with 4 minute change of trains

I am planning to travel to Switzerland on July 31st from ITaly.

I see this connection on sbb.ch website.

17:23 - Milano - Brig - 19:16

19:20 - Brig - Spiez - 19:53

20:03 - Speiz - Interlaken ost - 20:28

My question is , is the 4 minutes change of train from Brig to Spiez and 10mts between Spiez - Interlaken ost enough time to switch trains. Also would there be any kind of visa / passport check? I am US citizen and have US passport. I will also have atleast 2 big suitcases with me.

Thanks so much in advance for your help

Hi eurotravel6,

"Officially", the changes suggested by the timetable should be doable. 4 minutes is a bit tight, but as far as I can see it's a simple cross platform change. Passports will be checked on board, not while changing trains. If you miss the train, there's always a next one.You're not expected to use one specific train, apart from the one from Milano to Brig for which you probably have seat reservations.
