SimSig uses an 8×16 bitmap font which replicates the same graphics as used on IECCs, and the colours meet Network Rail standards. PC-Rail uses fairly correct symbology and colours, though it is stretched horizontally somewhat; however, colours are generally correct. SigCent and Traingames use rudimentary ASCII characters mixed with some graphics, but the colours are frequently wrong.
