I ve never used rail in Thailand, not even the SkyTrain in Bangkok. Just get the limo taxi from Bangkok to Pattaya. I use motorcycle taxis in Pattaya or just walk. I m gonna get a bicycle when I am back in mid January for two months. Anyway, I was in Pattaya for 27 days recently then I went to Taipei for business ( I am really into 925 Sterling Silver and Tanzanite now ) I am in Sydney now, quite ill, have very bad bronchitis I think.
