Combining "loco" and "community", the name suggests a creative ("loco" in spanish = crazy) community


To be creative and innovative you always have to be a little crazy ("loco" in spanish = crazy, but mostly used in a positive way). Of course "Locomotive" might also be associated, so Deutsche Bahn is in mind without being too dominant.
The subline is "OPEN INNOVATION LAB SHARED BY DEUTSCHE BAHN" gives some more detailed explanation but may only be necessary in some cases. (The layout is a rough version and should get some fine-tuning at the end)
