What technology are they using for signaling? From the photos, it looks like a bunch of relays connected with a bunch of red wires, but it must be more advanced

  Indeed it is - the Victoria Line uses ATO (automatic train operation), so nearly all of the train operation is automated. The system has been running since the 60s, you can read more about it here: http://www.trainweb.org/tubeprune/Victoria%20Line%20ATO.htm http://www.trainweb.org/tubeprune/Victoria%20Line%20ATO.htm

  London Underground use a number of signalling systems, here's a good resource to get started learning about them: http://www.trainweb.org/tubeprune/signalling.htm http://www.trainweb.org/tubeprune/signalling.htm However, ultimately you could develop a super intelligent system using networked PLCs, but at the end of the day you're still going to need relays to actually switch the power to the coloured light signals. The red wires in the photos will lead to a controller somewhere that triggers the relays to switch the mains power on/off to the signals.
