Mike is new to the hobby and is hoping someone can guide him:

“I am new at building a model train layout and I am about to install crossing gates and flashers. The part numbers are 30-11012 and 30-1104 respectively made by RailKing. I need to know what ITAD is opposed to TAD. I want to use the rail power to activate these devices on the single line where they cross a road and the instructions that come with these assume that the reader knows all about it. Can someone help me with this? How I am to hook these up?”
