Don't calculate the amortized (over a reasonable 30 years if you also ignore inflation and major maintenance/refurbishment costs) capex of the proposed Dallas red line northern extension, seen in a per-passenger-mile figure..... (I got 54ct per passenger mile just in capex (well, a capex-based view on the cost of having the track there and operable; costs from direct wear and tear of running trains and electricity and the trains themselves are additional)...)
