A department store seemed like a good idea (they don't need a lot of windows like an office building), and that corner just BEGS for a sign! This is the same idea already done by others, most notably by the "great Scaper's" conversion of this building to a movie theater.
In addition to the lights, signs, and minor interior details, I also painted the building a light brown/tan color, and gave it a bit of a dark brown wash to help make the building 'pop' a bit more (and of course, the take aware as much of the original plastic 'patina' as possible, although these buildings are provided already painted by Kato!). The crane on the roof and other details got some paint as well!
Below you can see one of the LED's being inserted through the shell for one of the building's signs. The l.e.d.'s are from LED Baron. I glued thin sheets of black styrene as the 'back boards" for the signs. The signs themselves are water-slide decals printed on a color laser printer.
And after completion, the building can now join the rest of the city...and the slow march to bringing light to every building of Quinntopia continues!
Another view of the city, this time showing the previously mentioned "Office building" and the 'flatiron scratchbuild' on the same block as the new "Printemps" department store.
Printemps" for the building? My formula is to basically find interesting stores, buildings or brands that reflect the same countries that the trains represent - and where possible generate good memories of my visits! So while Printemps is a distinctively Parisian store, it works with the Dutch Blokker, the English HSBC tower, the Japanese Uni-Glo store, Canon building and Sony scratch-build, (also a Japanese Mos Burger which shares a building with a Norwegian Elprice) and the German (basically!) Faller and Kibri building.
