-===== One other interesting option with these sensors: =====
+===== One new interesting option with GCA173 =====
-Using Loc-combinations, where one is a s.c. 'dummy-loc', which is not taking any current from the track, this combination might stop too late, where current detection is used and the dummy is in front.\\
+Real simulation of railroad crossing is done fine if you control everything via Rocrail.\\
-The use of two magnets -one at each front- will solve this problem simple and easy.\\
+But many grandfathers might let there grandson or granddaugther play manual with their fantastic setup.\\
+In that case, the railroad needs manual control as well, which might be a bit difficult to do.\\
+positioning the turnouts might be already sometimes a step too far.\\
+Now for this GCA173 there is nice task available to control railroad crossing, totally autonomic.\\
+There are several options possible:\\
+  * a single track, used only for one direction railraod traffic.
+  * a single track, used for both directions.
+  * a double track, where trains can pass in both directions.
+All of these options are possible with a GCA173 with special firmware.\\
+An explanation -how to- will follow shortly.\\

 The connection wires between Hallsensor and GCA173 can be up to 6' or 2 meter.\\
 Please be careful not to feed those wires parallel with rails and rail wires.\\
-A bit of twisting these wires will inprove protection to any distorsion.\\
 If that is inevitable, keep a distance of 4'' (10cm).\\
+A bit of twisting these wires will inprove protection to any distorsion.\\
 Straight angle crossing is no problem.\\

 ===== Connection to reed-switch =====
-Allthough GCA173 can work fine with reed-switch as wel, the option for wheel counter is NOT applicable.\\
+Allthough GCA173 can work fine with reed-switch as well, the option for wheel counter is NOT applicable.\\
 This due to the fact the the number of pulses, generated on the passing of a magnet is never the same, and unpredictable.\\
