RWS Version

Trucks are waiting in the Yard;
Tackling them with ease'll
"Show the world what I can do,"
Gaily boasts the Diesel

In and out he creeps about
Like a big black weasel
When he pulls the wrong ones out –
Pop goes the Diesel!

Trucks/Cars are waiting in the Yard;
Tackling them with ease'll
"Show the world what I can do,"
Gaily boasts the Diesel

In and out he creeps about
Like a big black weasel
When he pulls the wrong trucks/cars out –
Pop goes the Diesel!
