In railway business as in any other industry, the safety of workers is a chief concern. Each piece of rolling
stock has many safety attachments to safeguard the people working on it. Regulations establish how many,
what kind, and the location of all safety appliances on each type of railway car.
Exact measurements and locations are given for all safety appliances, such as handbrakes, brake steps,
uncoupling levers, running boards, ladders, and handholds. Tank cars have additional attachments, depending
on their construction; these are also specific in dimension and location.
