We are pleased to announce that the long-awaited functionality that enables an RFC routing-based calculation of infrastructure charge estimates is now available in the CIS. What does this entail? In addition to the conventional method, which is independent of RFC routing, the users can now define on which RFC(s) and which of their path segments they would like to make a query for a charge estimate. All nine operational RFCs are included and the inclusion of the two new RFCs (RFC Western Balkan and RFC Amber) is pending. Please note that the RFC segments have not been defined yet by PKP PLK, RFI and SNCF Réseau and the data availability and quality is continuously being improved in this regard.
