Watches and Trains

He took a walk through the train. There seemed to be a number of people working fruitlessly on various projects. As he went back to his seat compartment he heard someone whispering. Absentmindedly he pressed some buttons on his watch. To his surprise, it sent what he was hearing to a journal in his lap. The speaker stopped, grabbed him and dragged him to one of the people he saw earlier. In front of him was a wall covered in motherboards, CPU's, memory sticks and various other parts. Again he pressed his watch and it began scanning the motherboards. Blue lights appeared on whatever the watch scanned. He went back and forth till everything was lit up. A phone rang. “Yes, we'll take care of it” he answered. A compartment under the watch opened up and a large disk popped out. It plugged into the activated wall and a 3d printer was assembled. The main part of his watch could now doodle on paper with two red beams. He passed it off to someone else. “We are a shipping and transport company” he said, as the train quickly became an undercover rolling base for spies. The band of his watch did it's own scan as he went back to his original compartment. “Something's not right” as one of 'his' people set off an alarm after being scanned. They started attacking. The fight wasn't going to well for his team. The watch band switched modes and scanned again. It displayed the next likely move the double agent would make, the team reacted and the watch vaporized the stunned assailant.
