Opening the cover will set off an alarm, so don’t access the panel unless you plan to activate the brakes.

If the train has a cord and handle, pull it really hard to make sure it activates the brakes.

If you don’t have a red flag, try using a red shirt or some red fabric. Try to signal the train to stop as far away from the threat as possible so it has more time to slow down and stop.

Keep your opposite arm still at your side. Use only 1 arm to signal so the message is clear.

You can use a standard light if you don’t have any other options, but be sure to wave it back and forth vigorously so the operator can tell you’re signaling to them.

Shout, jump up and down, and do anything else you can think of to alert the operator.

Railroad dispatchers can even activate a train’s emergency brakes remotely if they can’t get in touch with the operator.
