How about some proper looking narrow gauge track from Bachmann.  Using the HO track was great to get the program off the ground, now that it seems to be flying strong and steady, its time to do some track.  Either set track style or without the roadbed, which in my opinion as most narrow gauge lines, espicaly logging didnt have any ballest.   About the only game is town is expensive Peco from the UK, I think PSC might offer it.  Some affordabe track with proper cross tie length and spacing is despriatly needed in On30 now that we have an awsome selection of locomotives and rolling stock.  Cheers   Mike
