Youtube Video on the Ghost Children from the San Antonio Tracks
Just a word of warning you can get ticketed for putting your car on neutral on the tracks.
To add to this story a few friends dared to go to the tracks and they didn't park their car like everyone normally does. What was strange was a woman walking on the side of the road with old clothes at 2am walking towards the tracks. Kind of creepy if you tell me.
Another Ghost Track Video I found on youtube.
