What year would You say this photograph was taken in?

This is an example of the kind of "Fun" that You can have by occasionally shooting black and white pictures on location. Although I had taken these vacation pictures in August of 1990, This picture looks like something anybody's Parents or Grandparents may have taken in perhaps 1954.
This scene was photographed at the end of the day at the Strasburg Railroad enginehouse. Just as it was during the 1950's, steam and diesel locomotives worked side by side in the United States and Canada. The diesel locomotive is a General Electric 44 ton centercab wich hails from the 1940's and 50's era. Steam locomotives were being "Phased Out" during this period, and many railroads litterally "Squeezed" every operable mile out of them before retirement or scrapping. The clothes that this family is wearing adds a sort of a "Period" feeling to the photograph. The big steam locomotive , Ex Great Western Railroad No# 90 from Colorado -a 2-10 -0 Decapod type freight service locomotive, is recieving some last minute maintenance before being put to bed for the night inside the Strasburg Railroad enginehouse. This definately looks like the 1950's steam to diesel transition period on American railroads.
