They want to expand light rail by running a line from downtown Portland to Tualatin, which at the current liar's budget would run to around $1.2 billion. Most in the "SW Corridor" don't want it, but they plan to ram it though anyway. Difficulty:
Federal law requires that a local transportation network have enough funding to operate and be maintained before federal money is used to expand it.
And that's where things get sticky; Tri-Met alone has over $1 billion in unfunded liabilities, and that sum is growing rather than shrinking. That seems to indicate that they don't have sufficient funds to operate and maintain yet another unwanted light rail line.
