Plan on taking the 5.55am or 8.15am train from Colombo Fort Railway station to Hatton in June. Would like to know the classes available for travel and seating options. E.g. is there an observation carriage, does it have air conditioning, is there a 1st and 2nd class? If so, are their individual seats or are there benches? How early should I buy tickets and can I do so over a mobile phone?
