Change at Jamaica for a train with no A/C

Change at Jamaica for a train with no A/C.
If you look beind me you can see this car is almost empty. The A/C isn't
working but, there is a sound of a fan. Maybe the heat is on. It's not
too bad. It's hot but it's not HOT, and the other cars are packed. At
least we got a seat, right.?
