An update of CTC has now been released.
It is available for download here
http://webrailroader.com/ctc/download-page/This version 3.7 includes the following changes:
Support of Single- and Double-Slip Switches
More variation of switches added (essentially rotating them around)
Sequence of signal movements and switch movements more accurate.
Territories using the new variations of switches will not show correctly with older versions of CTC.
We have also upgraded to a (hopefully) better installer package.
As always upgrades to previously purchased products are free.
