Thailand, Ayutthaya to Khorat (Khoran Ratchasima)

When I traveled from Bankok to Ayutthaya on the train,  unbeknown to me at the time, I bought a 3rd class ticket. It cost  20 baht - about 40p!! Got on the train, sat down and thought this is ok. Comfortable, upholstered seat, air con and fans to blow the cool air around! Five minutes later the conductor came round and moved me to where I should have been sitting!! Hard, plasic, moulded chairs, minimum 30 degrees and fans blowing hot air around!! Tried to upgrade but couldnt. It was only for 2 hours so no big deal and quite an experience. Bought a 2nd class ticket to travel today so got the air con etc, etc. Ok the journey time was an hour longer but the cost of the ticket was 300 baht - £5.50. Cheap as chips for someone like me but a huge difference for someone that only earns  a couple of quid a day!! I suppose looking at it positively, it enables the general public to move around a large  country at a very affordable price. Would have taken a shot or two of the countryside from the train but the windows were almost opaque where I was sitting!!
