An electronic control for a locomotive airbrake featuring field replaceable control portions having a minimum of pneumatic and electrical connections which are controlled by a redundant, distributed network of microprocessors. The relative alignment of the hypertext links may be controlled to unalign hypertext links that are in close proximity with one another and eliminate any overlap between the links, which assists in minimizing the inadvertent selection of unintended links. With this arrangement, mutually different operation voltages that are optimum for both chips can be given to these chips. A cable installation space is formed between the mounting wall and the lateral casing, and the mounting wall is detachably fastened to the frame stand by means of retaining elements.
