The next step in my layout building was to install lights. Here are a few pictures taken during that work. Click any of the pictures to view them in a bigger size.

Here are some of the lights which were installed.  There were altogether 40 street or railroad lights and about 30 light bulbs for the buildings.	In many cases I needed to add self-made masks into the buildings to allow for the illumination.  Like in this signal tower.  The first floor had a mask, but the upper floor didn't, so I added one.
The loco shed is illuminated with four Faller microbulbs.	This is how the station and the platform area looks like.  Here you can also see the signal tower with both floors lit.  The lights in the upper floor can be controlled on and off independently.
Also in this other signal tower the lights in the upper and lower floor can be controlled independently from each other.	Here is the power plant and the yard area in evening lights.
A view over the roofs.	These Viessmann lights give the yard a great deal of realism, although it may not be that visible in this photo due to the light coming through the window at the background.
The church is lit from the opposite side of the street with a small flood light beam.	And here is one of the houses in the village.
And the farm house in the woods.	This is how the "spaghetti" looks like under the baseboard.  The lights are divided into two separate circuits, both supplied from a standard Märklin 32VA trafo.  The overall intensity can be adjusted with the speed knobs.  The three Viessmann 5213 switching units allow to control the lights on and off from the PC.
