I'm going to sound like a heretic for saying this ...
I am
glad General Motors tore out all the National City Lines train lines.
Hear me out. The old routes served areas that might not make sense 50 years later. It used outdated infrastructure which would now be 100 years old. Many used unsafe center-run routes. Turning circles appear to be too tight to handle modern LRT cars.
By scrapping the old, we are able to build a modern system that is better thought out, better serve our suburbs, travel to logical urban locations, provide 21st-century safety, and can accommodate both slow-speed use downtown and high-speed use on dedicated right of way in the 'burbs.
Good riddance to the old system. I like the UTA one much better.
