I travelled through Malpensa T2 in June, intending to use the S50 to Gallarate to pick up a stopper from there to Domodossola (and on into CH).
This was thwarted by the summer engineering blockage around Stresa, and I used the direct bus instead.
On the way in to Malpensa (EZY from Manchester), the flight path overflew Gallarate and went way to the south before turning to land at MXP.
En route I took this picture which has MXP airport at the top, and Gallarate station and the Simplon route at the bottom.
It shows how close they are.
I can't see any sign of a new railway alignment taking shape in there, but of course it might be mostly in tunnel.
Current connectivity on the Simplon/Sempione route is rather poor with a 2-hourly stopper and very occasional stops on the CH-Milan EC trains.
Apart from the hourly S50 between MXP and Gallarate station, there is also an irregular local bus.
Edit:
Actually, forget the above photo as it doesn't go far enough to the north.
This one, taken a fraction earlier, does show a new surface alignment running mostly through forest from MXP to the Simplon line north of Gallarate, with spurs both ways.
The date was 10 June this year.
