Dress casual. Bring a sweater so if you are in one of the a/c cars.
I totally agree
It depends on which car you're in. If you're in the A/C car, then maybe something to keep warm. If in the open car, better wear something light because there's no A/C. So dress casual.
Definitely casual, I recommend dressing according to the weather.
Casual dress, depends on whether you are in one of the cars with air conditioning or not.
