It would be very useful to have a way of bringing geometry including turnouts between models i.e. as in the .alg files. Rather than having to use a dgn.
With large alignment files, they are a lot more manageable/faster when split into smaller sections so being able to separate alignments into multiple strings including turnouts and then combining at the end would be a massive time saver.
It would usefull have tool for export and import turnouts. When DGN file become corrupted, it would be helpfull to recreate project.
