Picture captured on November 12, 2023, showcasing an elegant black and blue train engine, adorned with a vibrant red and white stripe, majestically rolling on its path at the San Francisco Zoo. A beautiful combination of history, technology, and nature, it's not just a machine, it's a journey back in time. The strength of the wheels, the perennial plants in the backdrop, and a hint of a person enhancing the real life aspect – it's a perfect encapsulation of a day at the SF Zoo.
