I saw some photos from the early decades of the 20th Century showing a railroad at Hershey Park in PA. One of the pictures shows a train full of parkgoers without a locomotive of any kind. Also visable is what looks like a third rail in the middle of the two running rails. Was this railroad electrified? The "third rail" doesn't look electrically insulated from the ties in any of the pictures, but that could just be the angle they were taken from. If anyone has an info on this park railroad, such as the year it was discontinued, please post it here.
