Let’s face it: the principal purpose of train data recording has not changed that much over the last 120 years – speed, acceleration and deceleration are physical regularities which have not changed.
Obviously, recording speed and a handful of other signals will no longer do – since trains are more complex than ever, there is a barrage of information to gather which has either – in case of signalling data (such as ETCS information) – to be treated instantly whereas other data have a rather informative character and can be evaluated later on.
Modern railway vehicles are increasingly integrated and complex, therefore also data recording can no longer afford to ask for a special treatment.
It is Nirou Group’s utmost concern to highlight the recorded data’s potential value in all possible respects.
Nirou Group is a leading Power Electrical Engineering Holding in the field of manufacturing low and medium voltage electrical panels distribution-transformers, Automatic circuit-breakers and also installation and erection of high-voltage sub-stations and industrial project on turn-key basis.
Nirou Group is reputed for offering high quality, reliability and after sales services. The Group’s manufacturing facilities are concentrated in Rasht Industrial Zone, Esfahan and Mashad.
Customer satisfaction and quality orientation of Nirou Group, which is a strategic policy, are reasons for the good reputation that the company has gained.
Due to the government policy of extensions of Metro in big cities, Nirou Group have pursued the adaptation of the best possible, latest technology transfer for DC traction Sub-Stations.
