Those sound like the ATLS crossings, which require setup.
There's a slave, controller, and triggers.
The slave is basically an invisible train which triggers the crossing gates. To startup the crossing gates, however, your AI or your own train needs to start the sequence. This is where the triggers come in.
To get the triggers to act with each crossing they need to be assigned a channel number and be setup. accordingly for the particular configuration. There are many ways to set these up and it depends upon the situation. I recommend opening up the original JR session for editing and check out how those crossings are configured. Take screen captures and use those for reference. The screen captures, by the way, in Trainz are sent to the Screenshots folder wherever you installed Trainz TS12 to.
On the Quick Drive versus a driving session. A Quick Drive session does not contain anything you have configured before and is just that a quick, put the loco down and drive setup. What you want to do is run your session from the Route and sessions screen.
To see who is driving what where, press the 2-key on your keyboard - the one you hit for the @ symbol. This will put you in an external view and it will show you your driver's picture. Click on his or her picture and you will see your list of drivers. Should you click on any one of them, it will bring you to his or her location. You can then take over and drive any of these other drivers just like you are riding on or driving your own train. To take over control of an AI-controlled train, stop it by clicking on the driver bar on one of the little arrows which will bring up the commands list. Then click on stop. (You probably figured that out already).
But anyway, overall you are doing great with the program. Don't get frustrated and take things in, in bits and pieces.
