I've posted this on the HCMC forum but can't seem to get a straight answer!
On some websites, a daily train called PT4 shows up from Saigon to Phan Thiet. It leaves around 5pm and gets to Phan Thiet at around 9pm. As of yet I've been unable to find a website that can actually take a booking for it however.
If this train exists it would make a huge difference to my trip as it's far more convenient and conductive to our plans I'm HCMC. Can anyone tell me straight out whether this service is running or not or if it's a mistake on the websites I've read?
