Thanks for all the positive comments
The photos turned out a lot better than I thought because of the limitations of capturing the scene where the train stopped and the very dirty and scratched/graffitied windows on the trains.
In addition, the Sony is not as easy to use as the Df nor a Nikon DSLR. The quality is really good when conditions are good but moving train, dark stations and quick captures are not its strong suit. There is a significant delay and despite the focus highlights, it is too slow in getting the moment. It drains batteries rapidly so I turned everything off (eg picture review) and only used the viewfinder - it was like film days as I really had no idea what was captured until I got home.
Tom - the Sonnar has character and gives a slightly old fashioned picture - not a lot of contrast, hazy wide open, but tiny and quite fun to use. Despite the focus highlighting, you really need magnification to get it just right - which is too laborious for quick captures.
Akira - I too would have liked to get a bit more but too many people in the train and windows REALLY grubby where I seated. The fact that my carriage stopped right in line with the ship and was free of people on the platform at that instant was pure luck!
Elsa - train stopped right at the Central sign so the symmetry again was pure luck.
Thanks again everyone for positive comments.
