Hi Chris,
QUICK was for some time the German by-name of the (I think Danish) firm POLA. So in Germany the kits were sold under the brand QUICK. But now POLA belongs to FALLER, another famous German model manufacturer. Not only the railroads have fallen flags - mergers are just as common in the modeling business!
I checked the home page of FALLER, and it seems that they dropped the HO and N scale line. This is somewhat a pity, because POLA had quite a lot of interesting American prototype structures (i.e. the famous Chama coaling tower).
I also have the Rico station kit and I will place it on my layout. Picture will follow as soon as I have built and installed it.
