The Central Railway (CR) is planning to attach one more Vistadome coach to Chhatrapati Shivaji Maharaj Terminus (CSMT)-Madgaon Tejas Express, one of the premium trains on the Mumbai-Goa route, before this year-end, a senior railway official said. "These coaches with glass rooftops and wide window panes have proved to be a hit," CR's chief Public Relations Officer said.
