I would really like to provide you with photos...
Now I have some photos of a modern style building of this kind.
It looks a little different because it has no clinker walls—at least its main segment.
I took this photo with a friend's camera on March 21, 2009.
Actually, the focus was on the Desiro DMU (series 642). But it's hard to find a point where you can see the entire building. So this is the best compromise I could find.
It's at the old Dresden-Altstadt depot. For several years the annual steam locomotive meeting happened there—that time the largest event of this kind in Europe. But eventually Deutsche Bahn dismantled the middle section of this area. And in 2007 they built this new maintenance hall for DB's commuter trains there.
The aerial photo shall give an overview of the building. It's from Bing Maps because the aerial imagery of Google Earth and Google Maps is too old to show this structure.
As you can see, the only mountings on the roof are the light domes and some exhaust outlets.
The central part of this building (light grey or aluminium) is 151 metres (495 ½ feet) long and 26 metres (85 ½ feet) wide and contains the maintenance facilities with two tracks.
The western part (blue) is the wash plant and can also be used to unfreeze vehicles. It's 147 metres (482 ¼ feet) long and 7.65 metres (25 feet) wide.
The eastern part (clinker) is clearly lower. It contains the offices, workshops, stores, locker rooms, lavatories and break rooms. Unfortunately, I don't know the exact dimensions.
The following six photos were taken by another friend using his smart phone on April 7, 2013. He's active under the nickname "Wollex" at the German Drehscheibe-Online forum (http://www.drehscheibe-foren.de/foren/
It was kind of "open day" when we were there. So we even had a chance to have a look into the hall.
The first image shows the southern hall with a Desiro DMU (series 642).
On the second one you can see a double decker coach in the centre of the hall.
The third one shows a series 612 tilting DMU in the northern hall.
As you can see, the hall is mainly lighted through the roof domes.
On their open day they showed various wheel sets of passenger cars and MU's at the northern end of the building.
You can also see the metal cover of the building's side walls and the dimensions.
At the northern end of the building you can see the ends of the catenary in front of the building. But on the other hand you can also see that the building is prepared for a later addition of catenary inside because the doors are high enough for catenary and their gaps for it are only provisorily closed.
The middle door is for road vehicles providing the facility with equipment and replacement parts.
Interestingly, the wash plant (blue) is equipped with catenary inside. So you can see at the southern end of the building how the feedthrough is implemented.
I hope, these images will be a good inspiration for your next projects.
