Hi,

i´m planning to visit Bern and Interlaken on next winter (january) with my family. But I´m afraid of some possible problems that can be happen because the season chose to travel. How I visit Paris firstly, I´m planning to go to
Bern and Interlaken by train and come back to Paris to go ahead . If someone could help me clarifying some doubts, surely it can be very valuable to planning my vacation.

So does it usual to have long delays or trains closed because the weather in this region of Switzerland ? Probably, what kind of weather and temperature range it will be there (snowing, rainy, sunny days) ? Where should be better to buy coats: Paris or Bern ?
