Hi all, new to this board, to large scale RR'ing, and looking to buy a beginner set.  I've looked through past posts regarding Bachmann's version 5 upgrade but still have a couple of questions I hope someone can answer:
1. Can I assume that all G scale train sets in the current catalog are version 5?
2. If so, was there a particular year that all sets were mfg'd with version 5?
3. If not, how can I tell if a particular set is version 5, 4, 3,...?
Thanks for the help!
Jack
