Dear all,
following my forum posting from October there has not been any further feedback or feature request. Therefore, I suggest the following solution for railML 3.3 implementation of element <overCrossing>:
* add attribute @resistanceFactorPassenger to describe the tunnel resistance factor valid for passenger trains running through this tunnel
* add attribute @resistanceFactorFreight to describe the tunnel resistance factor valid for freight trains running through this tunnel.
The proposed solution is documented in the Git issue https://development.railml.org/railml/version3/-/issues/563

(1) tunnel resistance
Adding the attributes @resistanceFactorPassenger and @resistanceFactorFreight to element <overCrossing> seems to be a straightforward adaptation of railML 3 data model [1]. However, it is only half of the solution railML 2.5 provides, where a tunnel resistance can also be calculated from wall material and tunnel cross-section. So, dear community, are you fine with just the tunnel resistance factors, or do you need wall material and tunnel cross-section, too?
