I keep drinking water, and every time a local seller alights the train at one of the numerous stops we’re making, I buy a fruit juice, a can of soda or a coconut water. The sun is a beast in this part of the world and dehydration can be miserable.
By 2pm, my eyelids are drooping, like many other passengers, and despite my best efforts to read a few pages, I’m constantly nodding off, waking up only when the train gives an occasional jerk.
