Perhaps its a problem of perception in this picture, but the 25 km/h sign seems to be immediately before an S-curve in the track.

"Safe Speed" may be a generic term with a defined speed that trains should be traveling along the track when they are in the vicinity of limited visibility, near a platform or crossing. For instance, when operating heavy rail equipment, trains must travel at a speed where they can safely come to a stop in half the distance visible looking in the direction of travel.
Alternately, as defined by the Track Design Handbook for Light Rail Transit (US FTA, circa 2012), "Safe Speed" is "the speed limit above which the vehicle becomes unstable and in great danger of derailment upon the introduction of any anomaly in the roadway."
