Question: How does a Thameslink train know how full the carriages are?
Name: Lee, Banstead.
Qualification: Train driver.
Answer: The carriages have sensors on them and they know how much they weigh when they’re empty. They also know the average weight of a person. This means that as people get on and off they know how full they are.
