I can neither confirm nor deny any first-hand experience with connecting the two sides of the tracks with jumper cables in order to trigger the signal.

- qingcharles 4mo agoWe assumed it was some sort of electrical connection between the two through the wheels of the car. Is that how the trains activate it?
- aidenn0 4mo agoThat's how it worked 30 years ago at least. There have been upgrades to the signaling system since then, but detecting a circuit being closed is so simple and reliable that it would be odd to do away with it.
- qingcharles 4mo agoIt definitely surprised us that it worked with the car. At least we know it was accurate in the third BTTF movie when he rolls through the crossing ;)
