Each train would have a sensor which would be able to detect changes and update the database. Maps could easily be regional.

If you can update with changes on the fly, then you can propagate errors on the fly as well. There are likely some quite fatal corner cases that could be found the hard way.

It's a good thing we aren't using updated updated-on-the-fly computer systems for controlling powerplants, chemical refineries, trading on finacial markets or driving cars!
