SBB suggests a 13min connection at Zurich, feasible?

[signed]

I am looking at my options for my very early morning departure from Zurich Manegg to Lyon Part Dieu (I need to be in Lyon before 1pm)

My routing would take me from Zurich HB at 0604

The SBB planner tells me I can arrive at 0551 at HB on track 21 and transfer to Track 12 in 13 min

Is that feasible or should I plan to get a earlier S-Bahn

Zürich HB is huge but well laid-out and the general punctuality of things means that 13 minutes is very easily achieved.

However if you have the option and you'd prefer extra peace of mind (especially if you don't know the station) it might be worth getting the service prior.

 

[Re 4/4]

21 to 12 is no problem, but check the station map first. Once up the escalator, walk in the direction the train came from, it's slightly faster if you get out of the back of the train and use that escalator. The turn right into the corridor with escalators up to 3-18. 12 is obviously around half way through. I reckon reasonably fast walking gets you there in 5 minutes.

Was seamless despite 2min delay on the S-Bahn, thanks a lot
