Grade crossing signalling activates when a train approaches from a distance, and continues to remain active until the last car of the train clears the crossing. If trains only passed in one direction, a single occupancy detector could activate crossing signals directly. When trains move in either direction, things become more complicated.
For bidirectional traffic, three detectors are needed: one for each approach on either side of the crossing, and the short section over the crossing itself. In one direction, signals are activated when one approach is occupied and remain active until the section over the crossing has cleared. In the other direction, signals are activated when the other approach section is occupied and remain active until the section over the crossing has cleared.
Our Grade Crossing Controller, or GCC for short, takes the occupancy information from three detectors (or six, for a double-track line), and determine if the crossing signals should be active or not.

Ordering multiple kits: When placing an order with more than two of the same kit, bulk packaging will be used. This means that instead of separately packaged kits, the required quantity of each component will be packaged together. One or two separate components needed for all kits will be in a plastic bag or IC tube with a label or labels applied to indicate the component. One hardcopy of the assembly and installation instructions will be included with the order. If you require individual kit packaging, you must email us in advance or at the time of ordering. |
