To me this photograph illustrates the beauty and romance of traveling by a steam powered locomotive in the 21st Century, I feel it also highlights the gap between people in poverty and people living a well off life as the person in the photograph lives under the bridge the train is on along with his family and other families. I took this photograph while on leave traveling from Cape Town to Simon's Town in South Africa on 7 July 2013. If feel my photograph relates well the travel and vacation theme because the steam powered travel is a growing, powerful and unique form of transport for tourists to use in 2013 in Cape Town, South Africa.
