at a theoretical 80 mph between numerous stops...
Do you have a source for this deceitful misinformation that you attempted to append to the quote from the article???
Yeah - you can look up any train speeds traveling on freight tracks, with multiple stops - most US rails will not accommodate speeds above 80 in any case.
deceitful misinformation ... ? that's a nice turn of phrase, or do you work for the HS rail industry in the US?
