Bentley has a TR/CR system as part of their Select support. CR = Change Request, TR = Trouble Report.
However, you can post a CR here and sometimes it gets logged. Somewhere in the groups is a post about how to post a CR. As I recall, putting CR as the first two character of the subject is at least part of the "rules" for adding one here.
However, you should know that Bentley has released a newer version of most of these products - SELECTseries 3 which begins to store most of the design data in the DGN file. I do not know if the Rail / Track product has been released, but in the road and site side, it is called Open Roads. There, you can more easily drag alignments around and you get movement specific handles. But I have not really begun using it and am not sure of how and where spirals fit into this new technology.
