Want to travel from Indianapolis to west burke,Vt?

We want to travel from indianapolis to west burke,VT by a train or bus. How do we get to Vt with this type of travel and we really dont want to drive ourselves. Would like to see the country instead of buildings and cement. I looked on the the amtrack site and they dont have this travel. Like to go one way going and another way coming home. any sugguestions.
