This subject was touched on in a recent thread on the corporate vandalism of a Carlilse Pier railway station however I decided to start fresh on the subject as much the same damage is happening to this fine art not just in Ireland but in other countries.
The Art Deco period of the late 20's to 40's is my favourite when it comes to design, particularly in archicture of terminal buildings, railway stations, station furniture, marine designs, transport promotional posters etc.
Unfortunately there was not too much of it in Ireland partly due to the economic state of the country at the time however there are still some fine examples including the old terminal building at Dublin Airport.
In the UK there are quite a number of Art Deco tube stations on the Picadily and Northern line designed by Charles Holden
In the US new streamlined Greyhound bus terminals were designed in the 30's to promote bus travel.
I see Cunard have decided to use Art Deco as a centrepiece theme on their new QE2 liner, a giant mural taking up two decks designed by Linley
As someone mentioned, "if it has tracks running through it, it is exempt from preservation", this seems quite true and not just in Ireland.
In Poland there is a currently a campaign to save some of Warsaw pre war suburban stations from “modernised” (An all too familiar story}
Someone already mentioned about Derby Bus station which was leveled in 2006 despite widespread protests.
When I was in Seattle in the early 90ies there was much hype about the MV Kalakala, a futuristic car ferry designed in the 30ies that was used up until the mid 60ies, after that it ended up in Alaska as a fish processing plant and then abandoned. It was towed back to Seattle in the late 90ies and due to lack of funding it is currently in a sorry state tied up in Tacoma. In its former glory. Now, sorry state awaiting its faith..
