Original cost was basically at grade equivalent benchmark, for really flat terrain. Picture a new freight train line in the Mojave desert. About $100 million per km, excluding capitalized finance costs and rail system operations center, etc. =$3.3 billion for our 33 km route. Add other items back and you get to the vacinity of the first EIA numbers, about $5 billion. Of course, completely elevated rail is a huge cost. Typically unthinkable for low capacity system like ours. Add atypical rail equipment from Ansaldo, and you already know this bird had lead wings. $500 million per km is my outside estimate, but know there is no benchmark for this kind of unique system I know of off hand. I'm just going by the most expensive line project I knew before I retired and adding contingency, so WAG at $15 billion max. Should be much less, but prepared for by our leaders. Of course, who uses benchmarks in Hawaii? That's all kine messed up mainland talk our political leadership can't understand.
