Unlike the sister series, engines in TUGS do not have faces, and speak with megaphones, although Puffa was the only engine that could speak. The railway and The Goods Engine seem to be based on the New York Dock Railway, which was located alongside the Hudson River, in New York City. It carried out a very similar purpose to the Dock Railway in the TUGS TV series, and even had car float docks and Railway Tugs.
