As a result of user feedback and advice from a grade crossing signal technician, Logic Rail Technologies (LRT) has changed the timing of their Grade Crossing Pro (GCP) product. Crossing gates, if used, now start to go down sooner after signal activation (one second instead of 3); the signals turn off sooner after a train has cleared the crossing; and the crossbuck lights flash at a slightly faster rate.
Current users of Grade Crossing Pro can purchase upgrade microchips from LRT for improved signal operation by contacting them at info@logicrailtech.com
Note: I am in no way affiliated with LRT, but have installed their Grade Crossing Pro on a large HO scale club layout and suggested some of the improvements through our use of the product.
