Mumbai, March 4 -- The first air-conditioned (AC) local train connecting the Central and Western railways may begin in April when the new railway timetable takes effect. At present, while there are AC locals on the central, harbour, and western railway routes, there are none along the CSMT-Goregaon corridor of the Harbour line. According to CR officials, the CSMT-Goregaon route, has over 100 daily train services. "Keeping in mind the demand from passengers on the line, we are formulating a proposal to replace a few non-AC trains. However, this is yet to get a go-ahead," said a CR official. At present, there is a CSMT-Goregaon train after every two or three trains towards Vashi and Panvel. Railway sources said that although there are 300,000 to 500,000 commuters on this line daily, the issue with approving the AC locals may be the gap between the services since each rake would be able to operate only 12-14 services daily....
