The Train Engineer transmitters command 5
Aristo ART-5474 Accessory panels to control the interlocking
control system. Since the 5474 isn't configured to control a diode
matrix directly, the small circuit boards at the right contain the
signal conversion circuits. When the ART-5475 comes out, those
somewhat complicated circuits could degenerate to a bunch of
relays.
