Why do TRAINS

have CONDUCTORS?

Is it because there is a

tiny, hidden ORCHESTRA

playing music for

all of the PASSENGERS?

Machines are awesome!

There are thousands of

amazing machines at work

around us every day. Just think

of all the things we couldn’t build

or do without them!

Machines have truly changed the

world and our lives!

No, that’s silly!

A train conductor makes sure all the parts of a

train work together to make a well-running train,

just as an orchestra conductor helps all of the

musicians work together to make beautiful music.

The conductor operates many controls, like the

brakes and throttle, which control the train’s

speed, and has to manage the train’s total weight,

the route it will take, and make announcements to

the passengers.
