Yes Santiago de Compostela was the end of a high -speed line that was not fully commissioned as such. So speed limits were approximately 200km/h. The driver had been distracted as to his actual position and failed to slow the train in time for an 80 km/h bend. And yes the LGV Nord derailment caused some injuries but no fatalities. The 125mph ICE derailment at Eschede may not have been on a high-speed line - but killed 101 people. That was due to a faulty wheel set initially. but the combination of the derailed train hitting points and switching them into another position caused part of the train to diverge onto a loop line , one of the carriage ends struck a bridge support - demolishing it and causing a road bridge to collapse down on the train.
