Flumserberg, Engelberg or klosters all within 2 hours drive. also easily accessible by train too :) 

Can you advise me which train, how to catch it....................how much it cost

the sbb website has a snow 'n rail package where you can buy train ticket and lift pass all at the HB station for a discount. These are the regions close by with the resorts available, or pick which you want to see the others. you can get prices for train and pass there too by selecting which resort you want.
