I am planning on taking the regional train along the same route as the Bernina Express to Tirano/Lake Como on June 9th. I'm going to be staying in Interlakken and taking a 6:00am train to Luzerne. I want to be able to spend as much time exploring Luzerne before catching an afternoon train to Churn. My question is, when is too late to take that trip before the scenery gets ruined by shadows/afternoon clouds/sunsets. Apparently trains run well past sunset and I'm really interested in taking lots of photos on the trip. When is ideal light on the route? When does it get too late? The sun sets at around 9pm that day.
The afternoon trips that day are the following (leaving Churn and arriving Tirano). Any input on which I should take?
1200-1615 /
1300-1700 /
1400-1815 /
1500-1900 /
1600-2000
