Kadee has my undying respect and gratitude for inventing and marketing its highly successful HO coupler with the wire "brake hose" that allows remote uncoupling over a magnet. The "delayed" position is a further innovation that allows uncoupling where a magnet is not present. Kadee advanced the state of the art, and other manufacturers followed suit with similar couplers. Bravo!

My issue is dust on my layout and how you minimize or prevent it.  I am working on a two level shelf layout in a spare bedroom in the lower portion of a split level home.  There are two furnace ducts which are ceiling mounted for a forced air furnace that has an electronic air cleaner with HEPA post filter.  I always leave the bedroom door closed.  Even so, I have a considerable amount of dust accumulating. 

Which type are more common , this is purely for a scenic addtion to a yard area ('80s shortline) so just curious, as a websearch seems to show several variations in the number of holes. Incidently we call them chairs here in the UK and they are bolted to sleepers and hold down rail in 60ft lengths joined together with fishplates. Yes continuous welded rail is in common use now. Seems that only the gauge is the common link between us.

I am modeling the Erie Railroad, in HO, in 1951,  its centennial year of operation.  I am particularly interested in its fast freights dedicated to shipping perishables from Chicago to the NY metro area.  From what I know, the Erie had a dominant position in this market, surpassing larger rivals NYC and PRR.  A particular specialty seems to have been shipping California citrus to the east.
