Oh no they wont! there will be 16 of them on the footplate advising the driver and firemen on health and safety matters like,
1 Be careful its hot
2 Dont put too much coal on the shovel, it might be too heavy
3 Dont forget your goggles, helmet, gloves, safety boots etc
4 Risk assesment
5 And anything else they can think of so that they get a free ride on the footplate.
