The kit in the the original box looks like this - which seem to be quite rare and hard to find (it wasn't very easy for me to decide to finally use this kit, but I decided I don't wan't to become too much of a collector rather than a modeller!):
Although the original kit is composed of a very long station and a tall office tower section, I was mostly interested in the opportunities that the 6 story high rise section of this station provides. I was fortunate to find an unbuilt version of this kit and a built up section of the office tower which are the basis for the scratch-build.
Kibri produces this same station in HO scale, and also produced a similar station with the product # 7400 (see box below) which has a much smaller office tower.
I then had to figure out a plan to do the best job of 'merging' the old pieces with the un-built kit: This requires a lot of carefully cutting (using both a razor saw or hobby knife) and careful gluing.
For the ground floor I need to do something different as I didn't feel the original office tower ground floor would look right for a separate building. I re-purposed some of the pieces from the un-built Kehl station kit and was able to use them to create the ground floor windows and doors:
I decided to take a bit of a short cut with this building and not add interior details for any of the upper floors. The ground floor however would need a nice looking shopping look. I decided to create my own using strips of foam core and some self-created images and graphics of grocery store shelves. If you'd like a copy of my shelves and office backgrounds, its available here to download in pdf form.post or this post). The below shows the vertical sign with two SMD LED's on the top and bottom almost ready for attachment to the building.
