Here is a real good working IR based signal system. Full ABS for about $30/block, and no connection to the DCC system or a PC needed:

Have any of you used TDP`s abc master which is both a detector & signal driver in 1 unit and can be used for 4 blocks? If so please let me know your opinion. I am looking for a REASONABLE all in one to control multiple blocks on a HO DCC layout WITHOUT ANY computer connections. I would prefer the detection to be IR, and no I`m not willing or able to build them.I wouldn`t object if both the detector board was separate from the driver board as long as the boards were for multiple blocks.
