Nice post, Hammer. Check your PMs.
You're forgiven for your absence, Giddy. This once.
In order for Blossom to fake a signal, she'd need to wardrive the city systems, the security systems, or some of the emergency responder systems. In order to wardrive, she needs to be able to access a datapoint. The only datapoint she could access from inside the station would be that of the security booth itself, and she'd have to be inside the booth with the security guards to do that, or cut into the system from the outside of the booth which would require heavy-grade cutting tools capable of cutting through cement and metal.
The mechs are active. They constantly scan faces in the crowd and are outfitted with highly-sensitive sensors that can detect elevated heart rates, blood pressure, and tell-tale signs of extreme duress. But, as you've suggested, their Friend/Foe algorithms will not declare a foe unless commanded by the security staff, or the threat has obviously escalated requiring their services. Again, in order to take control of the mechs, Blossom would have to physically connect with—or use a construct to physically connect with—the mech and wardrive.
The scan stations are high-tech. Think of the airport security we have now and add biometric and cyberware scanning, facial recognition, and a catalog of known weaponry that the scanning searches against.
Here's a map of the train station for your viewing pleasure.
