Re: Pattaya traffic (PM Mailbag Friday, 14 December 2012) - The existing railway has already upgraded with double-tracks all the way out to Sriracha for over a year now! But only for 32 cargo-trains a day! Believe it or not! A double-track railway has the capacity of an 8-lane highway, and I find it very questionable that SRT does not operate mixed-traffic on this line with Sprinter-DMUs all the way out to Pattaya and Ban Chang. It would be very profitable!
