Another senior official of CR, said the AC local rake will be tested by a joint team of the Research Design Standards Organisation (RDSO), BHEL, Commissioner of Railway Safety (CRS) and railway's apex technical body, along with engineers from CR and Integral Coach Factory (ICF) where this coach has been built. He also informed that the speed of the silver-blue coloured AC local train will be limited to around 50-60 kmph during the first few trials. Built at a cost of Rs 54 crore, the first AC local train has no general or first class compartments, but two of the 12 coaches could be reserved for women apart from the fact that entire rake would be vestibule connected (in two parts of six coaches each). Operation of AC local on Mumbai suburban services was announced in 2012-13 Rail Budget but initial hiccups and impediments, delayed the project.
