Hi.
Just to confirm that by default TRC crossings are not compatible with standard ITs from N3V. EITs has included an option, that if enabled makes EIT compatible with TRC crossings. In fact when the TRC option is enabled, the EIT will at initialization ignore and skip any TRC crossing included in a path and will let the TRC system still manage the crossing. If the TRC option is disabled, the EIT does exactly the same things than standard ITs and will manage all the crossings along a path.
Hope this helps understanding the relation between EITs and TRC crossings.
Regards.
Pierre.
