50 min connection time enough?
After a 2.5h ride from Haiphong/Halong, I'll arrive in Hanoi station at 21:10. Then, I need to get on the last train for Lao Cai (Sapa) departing at 22:00. Both trains dock at Hanoi station, although I may have to cross a street to get to the other side of the tracks.
My concern is the first train may be late. - Should I be concerned and What would be the min time I should expect to make the connection?
