It’s a Happy Little Train:

The Zoo has a train with a high-pitched whistle. I can hear it all the way over at the Intern House. Every time that whistle blows, it brings to mind the film: “The Bridge on the River Kwai”:

It’s a popular attraction and it’s just such a wonderful, replica of a steam powered train. This is a really beautiful train.

But it has this high-pitched shrieking whistle exactly like the train that bites the dust in the film. Happy little kids and all I can think about is Alec Guinness in the final scene:

I am so “not right”.
