This cache is at the fanwood train station and is not on the train tracks. I repeat not on the train tracks. The cache sits right next to the fanwood museum and the fanwood train station. There might be a lot of muggles nearby so stealth is needed. The cache is in a very small container. THE CACHE IS NOT ON THE TRAIN TRACKS.
