Absolutely right about high-speed LD trains. In addition to the Lakeshore Limited, both the Silvers, the Palmetto, the Crescent, and the Cardinal all operate at speeds of up to 110 mph (180 km/her) on large swaths of the Northeast Corridor. In fact, the NEC trains, both the Regionals and the Acelas run at speeds of 200 km/hr (120 mph) or more for large parts of their runs, perhaps a far greater percentage of the total run than the Brightline trains are going to be running at 180 km/her, and the NEC trains have been doing this for decades.
