Crush load

Imagine you are playing with a bunch of toy cars and putting them in a box. You keep adding more and more cars into the box until it becomes full and you can't fit any more in. That's kind of like what happens with crush load.

Crush load is the maximum number of people that can fit into a train or subway car without causing any harm to the passengers or the train itself. It's like the box of toy cars - you can only add so many before it becomes too much.

Trains and subways have a specific amount of space inside the cars that people can occupy, like seats and standing room. When too many people try to fit into the car, it can become unsafe. It could cause people to fall or push each other, causing injury.

Additionally, when a train is overloaded with people, it can put a lot of pressure on the train tracks and the train itself. This can cause damage and make the train unsafe to operate.

So, when you hear about "crush load" it means that the train or subway is full to its safe capacity, like the box of toy cars being full. It's important to pay attention to the signs and limits set by the train or subway system to ensure everyone stays safe.
