 ===== Description =====
+When grandpa is urged to go to his model railroad room with his grandson, this young offspring\\
+probably is not (yet) interested or impressed by automatic train control by the fantastic Rocrail.\\
+Instead of that the boy wants the run the trains himself.\\
+And that creates a problem when the railroad crossing is also controlled by Rocrail.\\
+This unit can work with Rocrail as well, but there is no need for.\\
+The set contains of a central controller GCA RRC 01 where the needed sensors are connected, \\
+and for each servo a small controller board, which has also connections for lights and \\
+-if desired- an output to start any addinonal sound unit.\\
+For each track (in one direction driven) there are two sensors needed.\\
+One sensor to activate the barriers and lights, which also counts the passing wheels, and the second sensor,\\
+positioned shortly after the crossing, to count down the passing wheels, and when counted down to zero,\\
+free the crossing for impatiently waiting traffic.\\
+Two way direction is also possible, as well as double track.\\
+Each direction or track requires its own two sensors of course.\\
+For each use, special firmware is optional.\\
+The same sensor is able to work with N-track, HO-track and larger.\\
+More to be published after final tests.\\
