There are at least two dock yard engines who shunt on a railway in New York City.
When Vinnie arrived back to America after The Great Railway Show the dock yard engines shunted some trucks for him to pull to the Big City. However, Vinnie started bragging that he could pull more. Because of this, they then added on more trucks to the point that Vinnie couldn't pull the train.
The two engines are based on H.K. Porter 0-6-0ST. They would be seen in the in the dock sides of New York City just like they were featured in the short. However they where incorrectly portrayed with buffers and chain couplings. Porter and B.E.D.T. 15 are also members of this class.
Both of the engines are painted identically to Porter. They are painted viridian with yellow stripes, lining and brass fittings. They have a gold star on each side of their lamp and red window frames.
