Caption: Line 28 car 546 is about to stop at the station here (Lg. Portas Sol, I believe). Just to the right of the photo the line narrows to a single track and then splits in two. The two-way Line 28 goes to the right, while the one-way Line 12 comes down the hill and joins Line 28. This and the next 7 photos were taken during a lemonade break we took during our tour of the city.
