I am travelling in the first week of March to the great wall

I see the in is available to go to the Badaling in the morning, but in the evening I see the train is at 19:30 which is too late, is it true? or is there any other way to come back to city ?

Can I cover Ming tombs the same day?

if yes would it be better if I can come back to Ming tombs on the way back to the hotel ?
