Transportation - Battambang, Cambodia
The main means of reaching the city is via buses from Bangkok, Phnom Penh and Siem Reap. The airport is not much used, and the passenger rail service has not yet been restored.
There is also (except during the lowest water levels of the dry season) a daily boat connection between Battambang and Siem Reap via the Sangkae River. Since the buses are faster and cheaper, the scenic trip is nowadays used mainly by tourists and some locals who live along the river.

There are many Bus companies like Giant Ibis, Mekong Express, PSD Xpress, Sorya Bus, Neak Krohorm, Thero Express (15-seat), Larryta, KSO, Virak Buntham, Kampot Express, Cambodia Post VIP Van offering bus/van services to Battambang town using modern air-conditioned buses/vans.

Train
The old saying goes there is no such thing as a free lunch, but in Cambodia, the old train is still free. for foreigners, that’s it. However, it will just cost you some time (maybe some officers will ask you for a creative donation). The Phnom Penh to Battambang journey usually takes about thirteen to fourteen hours, if no mishaps occure. The scenery is not nearly as stunning as parts of the Phnom Penh-Kampot-Sihanoukville routes, but you certainly will get a good sampling of rural agriculture scenery.
Congratulation!
