Specs Of Trains FG Ordered For Lagos-Ibadan Railway
In an earlier reportage, it was revealed that the federal government has paid for some locomotive trains. These trains will be used for the Lagos-Ibadan Railway and for the Abuja-Kaduna railway respectively.
AutoReportNG did a review of the trains the federal government is buying, their images and their specs and these may interest you.
1. NDJ3 Quasi-high Speed DMU
NDJ3 “Harmony and the Great Wall” DMU is developed under the transportation demand of Beijing Olympic Games, which commutes between Beijingbei and Yanqing. This DMU is a “2 motor-cars and 7 trailing cars” unit with one motor-car at each end and seven trailing passenger cars fixed in between. The locomotive is equipped with 12V280ZJ diesel engine. The Maximum running speed is 160km/h.
Based on mature technologies, long-term operation and inspection results that got from medium and large overhaul, the performance and reliability of main components such as diesel engine, bogie frame, car body, traction motor used for NDJ3 DMU have been well verified. It is well suited for long steep grade.
Since NDJ3 DMU was formally put into operation in 2008, this train set has been running safely and reliably for 8 years and was well recognized by customers, It was awarded the first Prize of Scientific & Technological Progress of China Railway Society in 2009.
