After a small accident by my 3 year old grandson, the engine for the Wonderland Express train set item No. 25001 was severely damaged by contact with the floor.  Is it possible to replace this engine?   It is a favorite of both Grampa and Gramma and we would like to replace it if possible.  It is part of our Christmas layout and the other 5 grandchildren are upset that the train may not be a part of next years Christmas layout.  Thank you for any help you may provide.
