You have to catch which train from Porta Garibaldi ? Long distance have
most moved back to Centrale (at least Italo).

A Frecciarossa to Torino.

I see.

In retrospect I probably would have been better off with the Malpensa
- Torino bus even if I dislike long bus rides.

Or a direct flight to Torino :-)

It is rather inconvenient to go "back" to Milan which is in the opposite
direction w.r.t. Turin. Unfortunately any other connection will be more
adventurous ... like ...

Bus from MXP to Gallarate, then regional train to Rho, then regional
train to Turin (unless some Frecciarossa stops in Rho) ?

Train from MXP to Busto "FS" (a few trains from MXP go there, note it is
not Busto "FNM") then as above.

Train from MXP to whatever intersection on the Novara line (most likely
will be Busto "FNM"), then train to Novara Nord, short walk to Novara FS
then regional train to Turin (I am not sure if any of the fast trains on
the new line go through Novara)

It's fairly common to have a cluster of hotels near a major airport.

Yes, except that Malpensa is an aborted major airport. And hotels I was
aware of were displaced towards Gallarate and the motorway. Case Nuove
was known in the press as a place become unpleasant to live after the
airport extension because of the noise.

There's a shuttlebus between the two terminals and it looks like there
are bus stops

I don't think a free shuttle bus running between two airport terminals
will show up in a timetable database.

It depends on the kind of authorization it has from the Region. It is
unlikely that a shuttle inside the airport has stops outside !
