If the heat lamps aren't on and you try to turn them on, you'll activate a loud message that says "customer needs assistance on platform one." No one will come to assist the customer of course--good to know in a real emergency--but everyone will look at you. Nor will the heat come on.
Wayfinding
If you're getting off at an unfamiliar stop, the train loud speaker system that calls stops will be broken.
If you ask someone if you have the correct stop, they will always say yes whether they know or not, trying to be "helpful."
If there's an overhead map, the area you are trying to go to will be covered with red paint graffiti.
Finding a Seat
When a train car is full except for one seat, the seat will be covered with what you hope is Sprite.
If there's another seat, it will be next to the end doors where you'll be the first person that emotionally disturbed people and panhandlers see when they move from car to car injuring your legs with the door.
