As plans are now in place to manufacture 250 Air-Conditioned (AC) local trains to convert the entire fleet of Mumbai local trains into AC ones under the Mumbai Urban Transport Project (MUTP), the Mumbai Railway Vikas Corporation (MRVC), the official railway think tank and coordinating body has called for proposals on how to make the historic shift happen with least inconvenience to commuters.

Five AC locals for the Western Railway have already arrived in Mumbai and are under various stages of trials.
