Hi.
May be you can explain more in details why you want to use track circuit blocks and why invisible signals are not good enough for your usage to protect some track sections.
As John (Vostrail) has explained, Enhanced Interlocking Towers (EITs) assets enable to use on option track circuit blocks, but there may be some other scripted assets usage not documented or under construction. But if you have some new interesting ideas for track circuit block usage, let explain them and we can tell you how to develop such script or even develop it for you if it is of general usage for the community ...
Regards.
Pierre.
Hi
I use these with Pierre's Enhanced Interlocking Towers and commands to control multi track stations and yards with trains automatically searching for an unoccupied track. They work very well when set up correctly. As mentioned above, they can be used to control single line sections very effectively as well.
The one drawback in that situation is if it is a very long section where normally trains traveling in the same direction would be allowed to follow one another through. In those situations I still use the Enhanced Interlocking Towers but not the track circuits. I use a couple of variables, one to indicate if the section is clear and one to indicate direction of travel if it is occupied. This also works well and keeps the traffic flowing on busy routes.

Track warrants are used to allow a train to travel from Point A to Point B. Lets say 'A' and 'B' are stations. Train 1 gets a warrant to occupy track from station 'A' to station 'B'. No other train can be on that stretch of track until train 1 clears up its warrant. In trainz I would use it to hold trains at certain points. Lets say train 1 is west bound and train 2 is east bound. Traveling towards each other there is a section of track where its single main. Train 1 gets there first and proceeds west. Train 2 would have to wait in the siding until train 1 clears the circuit there by clearing their "track warrant". Then train 2 may proceed east. The same thing could basically be done with haveing train 2 wait for train 1 to trip a certain trigger, but I think the circuit system could be used to make the process more automatic.
