I think it is interesting to see which train teams were probably on from Brussels to Schiphol Airport southwest of Amsterdam. Sunrise statistics indicate sunrise for July 8 at 538am and I believe from the Extra Videos that it was still slightly before sunrise. That translates into a 550am train and a 728am arrival at AMS. It's possible that not all teams were on that, but at worst they would be one hour behind and at 828am arrival still about 5 hours before departure to Panama City.
