Cache is a little larger than normal micro (about 3" x 2.25" x 4.5") well disguised and sheilded from the elements. It seems finders get excited and forget just where they found this cache, so try and notice where you take it from and replace it in the same location.
Do not climb on the train! There are currently several no trespassing signs on the train placed there so that people will not climb on it and get hurt. You are allowed to use the park and enjoy the train from the ground.
NOTE: There is also a letterbox at this location. Please make sure you have found the actual cache when you log this find. It IS NOT a plastic food storage container. When you open the cover, it will say Old 470 on the inside of the lid. If you are unsure, ask or look at the spoiler pic below.
