I'm looking for an animated short that may have been shown on Sesame Street. The film I'm looking for takes place in a world in which toys are alive. A child has a toy steam locomotive that she loves very much. The child receives a second toy, a modern streamline train. The modern train is jealous of the steam locomotive and competes with it for the child's affection.

I don't recall any words, only sound effects made by musical instruments. A percussion instrument is played when the steam locomotive is moving to imitate the clickily clack that a steam train would make and a string instrument, most likely a violin, to mimic the constant sound that a modern train would make.

Does any of this ring a bell? Any information you may have helps to find it.
