I model streetcars in O gauge and HO.  For many years I have been using the EZ Street track system for O gauge trolleys and have been very satisfied with the format.  Has Bachmann ever considered developing EZ street products for HO gauge?  In the 50's and 60's TYCO marketed a track system called "The Old Strap Hanger" that included a single truck trolley similar to the Spectrum Birney cars, and an oval of gray plastic street track with brass HO rail.  Unfortunately the TYCO track sections were never sold separately and there were no special track work items like switches or crossovers.  Given Bachmann's expertise with regards to O gauge EZ product it seems like a no brainer for HO.
