What is the incremental cost per mile (infrastructure and equipment) to go from a top speed of 79 mph to 110 - 125 mph?  And what is the incremental cost per mile to jump the speed from 110 - 125 mph to 187 - 220 mph? If 110 to 125 mph would meet the needs of 80 to 90 per cent of the population where train travel is potentially viable, i.e. relatively short, high density corridors, what is the commercial justification for incurring the extra expense to gain a top speed of 187 - 220 mph. Commercial justification means that the system can recover all of its costs from the fare box. The French and Japanese claim that their original high speed lines are profitable. That's probably true if one overlooks the fact that the taxpayers absorbed the up front depreciation of the infrastructure costs before the lines were reorganized and privatized or semi-privatized.
