Victorian and Georgian architecture has looked good for hundreds of years. Never seen as "ugly".
I'm sure it will always do so.
There would have been people that would have seen them as blots on the landscape indeed many land owners insisted that railway compaines built in a certain style before they removed their objections.
Why they can't build a Victorian/Georgian style building for the station I don't know!
Cost is one thing, a Victorian/Georgian style signal box building is not fit for modern way of working.
The railways have in their 200 years been innovators, as engineers we are always looking for new ways of doing things, having said that if there is a way to reuse existing building then we do and example is the reuse of St Pancras, the way Paddington is being transformed, Blackfriers and soon London Bridge Stns. Must admit Reading is very radical reuse of space

We (the railways) cannot stand still, if we dwell in the past we will not serve the country.
While I enjoy seeing preserved Victorian/Georgian buildings as much as I enjoy Tudor and medieval I also like the Shard and the Gherkin
