I have a external animated scene, how do I link a model?
It's easy! From your external blend scene go to "File" - > "Link" (CTRL+SHIFT+O) -> Select the PlayRoom.blend -> Inside the file RNA choose : "Object" -> then click the name of the desired object on the file eg:"Train". And be shure ,before you click on the "Link from Library" Button , to check the "Link" option (if you want to keep the relation) or uncheck it if you want a local copy of the model.
