The Indian Railways will start the testing of the much awaited indigenously built semi-high speed "Train 18" from September, official sources said.
According to Railway Ministry sources, "Train 18" is expected to be rolled out in September.
The train will be inducted in the railways fleet only after thorough testing, the sources said.
The Research Design and Standards Organisation (RDSO), a technical adviser to the Indian Railways, will conduct the tests and give its validation to the train.
"Train 18" was earlier scheduled to roll out in July.
Built by the Integral Coach Factory (ICF), Chennai, the train will promote "Make in India", and is capable of running at a speed of 160 km per hour.
It will be self-propelled on electric traction like the metro trains and does not require an engine to run.
