Control system for a railway crossing having signal inputs (S) and signal outputs (AC), and processing logic (P). The processing logic includes a channel A part (PA) and a channel B part (PB) for each railway crossing logic function (such as controlling white and red lights). Each of the channel A part (PA) and the channel B part (PB) has an AND logic gate (AA; AB) receiving a direct signal (DI-A; DI-B) and a cross check signal (DI-AtoB; DI-BtoA) and outputting an internal data signal (DII). The cross check signal (DI-AtoB; DI-BtoA) is provided by a first data exchange channel (SE-A) between the channel A part (PA) and the channel B part (PB). The processing logic is implemented to provide the control system with a sufficient high availability and reliability depending on the requirements of the specific railway crossing logic function.
