Siemens lands mandate for two mobile substations
Siemens has been awarded an order to supply two mobile substations to National Grid SA, the transmission operator of Saudi Electricity Company. Based on the unique specifications from National Grid SA, Siemens has combined its existing innovative mobile substation modules together to design and manufacture two 380kV mobile substations able to fit and suit in any network area of the kingdom. With a rating of 502 MVA each, these two high-voltage mobile substations will be the most powerful ever built in a single feeder configuration. A mobile substation is mounted on a special trailer and can easily be transported wherever needed. Read more
Dual-mode locomotives poised to offset electrification delays

Railway electrification in India has been a phenomenon where much has been aspired but very little achieved. The government has always wished that diesel traction is phased away so that the annual import bill of billions of litres of diesel is controlled. Besides, the growing environmental concerns associated with burning of a fossil fuel like diesel can be mitigated. Railway electrification is never an easy task because it has to be carried out on live and running tracks. Railway electrification has by and large been a tardy process except in recent years (See Box: Pace of Electrification). However, the task of 100 per cent railway electrification remains elusive.
