Changing Platforms - How much time required

I was exploring the time table from St. Gallen to Brienz. In the suggested option we have to change the trains at Zürich HB and Luzern which I suppose are quite big and busy stations.

At Zurich we have to go from platform No. 13 to 3 in just 11 minutes and
At Luzern we have to go from platform No. 6 to 12 in just 06minutes.

This is subject to earlier trains running in time. If it gets late the available time for change over will be still lesser.

For the group of 5-6 people is it practicable.

Thanks and Regards

Hello AtulBhide,

Normally spoken trains are exactly in time in Switzerland. I think you will have enough time to change trains/platforms. To make sure you can always ask the train personnel, they will be able to tell you what to do to get to your connecting train quickly.
