I dont understand Amtrak website (im from argentina). It looks like some trains departure at 3:52 am? How can that be possible, i mean the station opens at 7:30! Or maybe i am misunderstanding the website? What is 3:53a ?

Yes.. there are station conductors and masters to help around, ticket counters opens later.. but doors and waiting hall will be open..

But train door is closed mostly after 11:30pm but they open door for 3:00am...but just incase if you find door is closed then use left side door is mostly open after 3am...if anything need any help from trian station guard is available and he can open door for you and can answers all your questions... I hope this'll help you. Thank you
