You can get on the train in a number of locations like for instance when you walk into Disneyland there is a train station literally there you just have to go around and up the stairs
Go to Fantasy Land, but just be prepared to wait in line. Just came from there and i had to wait for about half an hour.
There should be a station by the winnie the poo' area.
