Thai trains are rarely on time. They usually leave on time from the line departure city and always accumulate a more or less important delay. Train is the cheapest transportation in Thailand. You can book your tickets in advance online (book here). For sleepers in overnight trains, it is strongly advised to book at least 8 days in advance. For 3rd class tickets is not necessary to book in advance but know that you will not get a specific seat and depending of the passengers number you may not be sitting. But traveling in third class in Thai trains is an experience to live for its atmosphere. Have a nice trip from Nakhon Ratchasima to Nong Khai !

The atmosphere of Thailand night trains with their restaurant car turned into a nightclub is truly amazing! It is often a memorable trip though you can't enjoy the landscape. To be sure to have a sleeper, it's recommended to book your tickets in advance via booking websites like 12Go.
Khao San Road is known as the backpacker's area in Bangkok. Travel agencies and transportation companies offer bus or ferry + bus packages from Khao San Road to the popular Thai islands like Koh Tao, Koh Samui, Koh Phangan... but also to other destinations in the country.
There are direct buses from Bangkok to Phnom Penh or Sieam Reap (the city near Angkor) in Cambodia with border crossing included in the trip. Buses depart from Mo Chit Northern Bangkok BUS Terminal. The number of seats is limited so it is better to book in advance on 12Go.
