Cue
Cue, a minimalistic identity marrying the traditional ritual against the modern components.

Solution

Cue, a signal or a nod given to proceed. Here it symbolises the traditional german railway signal from a semaphore used by Deutsche Bahn in the past at a 45 Degree angle shown to clear trains to proceed to the next point and this is reflected with the modern minimal elements of design. There is a PayOff line "Clear Innovation" that supports the parent identity of Cue and the logo.
