The bridge gives such a good sense of scale that it's as if the railway builders put it there for photographers.
Thank you, all.
John - your follow-up suddenly reminded me of a very old image of Doodhsagar on my hard drive! I am attaching it here and shall also add it to my blog post. It was taken by the legendary photographic team of Souza & Paul
who were active from 1890 to 1910 in Goa, and to whom we owe so many priceless photos of that time. Their photo shop
in Panjim is now run by their descendants.
I took a photo of their photo from the Central Library Archives in Panjim several years ago. This railway line and bridge was built c. 1890 after an agreement was reached between the Portuguese and the British.
