There are several ways to go about adding signals to a model railroad. Most require a computer connection and separate programs and hardware. One is CTI at www.cti-electronics.com, another is the Digitrax system using the SE8C and loco net. See www.digitrax.com. Both require detection of block occupancy and/or turnout position detection. Atlas has a system also that is reported to be fairly simple and doesn't require a computer. However, the most versatile and complete systems will be computer based. All this means that you will need or should have a basic knowledge of electronics and wiring, and know a little bit about programming. If you are not willing to get this knowledge, go with the Atlas system.

The above is my opinion, from an active and experienced Model Railroader in N scale and HO since 1961.
(Modeling Freelance, Eastern US, HO scale, in 1962, with NCE DCC for locomotive control and a stand alone LocoNet for block detection and signals.) http://waynes-trains.com/ at home, and N scale at the Club.
atlas makes a signal system and very nice signals. go to customsignals.com and check out their plans which is what atlas bases their system on. i'm currently building my own system with atlas signals, dallee current detectors, 12volt relays and circuits of my own design. while planning my system i determined i could get a system to work the way i wanted it to and be a little cheaper to construct than using a ready made plug in system.

I think there are 2 questions, first one for us to ask you: Are you running DC or DCC? This will make a big difference in the best way to go about this.
Second is a question to ask yourself: What is your idea of a working signal system? Do you want the lights to turn red as the train passes, and then clear as the train gets further down the track? Do you want following trains to "recognize" the signals, and stop when they see that they're red? Or, would you be happy with a signal that was green when the turnout ahead is set for your train, and red otherwise? That's a much simpler project, and still gives the illusion of a signal system without all the complexity.

You may also want to look at the ABSMaster from TDP & Associates, Inc. They offer a 4 block signaling syatem that works with any manufacturer's signals and is independent of the operating system (DC / DCC).
