Here is the kid's version (an echo song), author unknown:
Down By the Station
Down by the station
(Down by the station)
Early in the morning
Early in the morning)
See the little pufferbellies
See the little pufferbellies)
All in a row
(All in a row)
See the station master
(See the station master)
Turn the little handle
(Turn the little handle)
Puff, puff, toot, toot
(Puff, puff, toot, toot)
Off we go!
(Off we go!)
Down by the station
Early in the morning
See the little pufferbellies
All in a row
See the station master
Turn the little handle
Puff, puff, toot, toot
Off we go!
