Whatever happened to TT scale? - Model Railroader Magazine

TT is a scale.  It was invented here but never blossomed here.  It is great that the Euros and Russians took to it.

Let's face it, however, until rather high scale US type locos and rolling stock appear, coupled with TT scale autos of american cars and trucks and perhaps some TT scale basic US type structures, the scale is just not going anywhere here. 

HO and N are locked into the U.S. market and are the bulk of all MR sale volume.  O and HO narrow gauge materials are coming alive because there are O scale and HO scale people and buildings to go with these scales narrow gauge offerings and have been for years.

TT scale U.S. people and cars and structures are just non-extant for the most part here.  There are a few diesels of U.S. type that are produced in TT, but the selection is abysmal.

Most folks who are MRs want good faithful replicas of their favorite motive power and rolling stock.  Unfortunately, it is just not there in TT.

I am not against the scale.  Successful U.S. manufacturers just don't see any money in it at all.  That is what happened to TT scale in its country of origin.  The intial interest in it was low and remained so just long enough for N scale to blow any remnants of it here out of the water.

Technology was not there for TT's introduction and the advance of technology to the degree than N scale was viable, killed TT.  A double technology whamy slammed into TT and K.O'd it in the U.S.
