Overall the train itself no serious issue, but need to be sure it is Station B , not Station A(unable to search station B from google map/waze). Quite far apart if by walking especially if you are late.
After showing the ticket and enter the train platform, you might see some "extremely good" guys helped you to your coach. Until you settled down, he will ask you to oay him tip. He complained 50k vnd is not enuf, until i increase to 150k, only he left. Be careful!
