As observed at ET...

I think this is largely for gaussjordan's benefit, or something. At any rate, the int0rw3b tells me that the reason I haven't actually seen any Boeing-Vertol United States Standard Light Rail Vehicles is that 14 of them were scrapped in May, leaving only 18 in the entire Green Line out of some 188 active cars. Also interesting is that, of the 20 so-called "Type 7 1/2" cars, only one (3700) has gotten the internal rework to interoperate with the ever-so-doomed Breda Type 8 cars.
