I know we're long past debating the stimulus, which was EXACTLY AS BIG AS IT NEEDED TO BE thankyouverymuch, but my local transit authority has plenty of immediate needs. Immediate as in 10 years ago. Bits of it are kept together with chewing gum. Starting in summer, the Norristown High Speed Line will not, in fact, go all the way to Norristown because the bridge has reached the end of its life. I'm pretty sure that there are a couple of engineers who can't sleep at night because they're worrying about City Hall station collapsing entirely, bringing City Hall with it.
Money's cheap. Borrow it. Spend it.
