&gt; Almost all Dutch intercity trains run 140km&#x2F;h, and that&#x27;s fast enough<p>When it&#x27;s hard to find cities more than 100km apart, sure. And the US already have passenger trains in that range.<p>&gt; Of course cities are close together here, but we are in Europe.<p>I quoted what&#x27;s considered high-speed rail in Europe, I&#x27;m sorry that offends you.<p>&gt; I&#x27;d certainly call 200km&#x2F;h &quot;decently fast&quot;.<p>Not when your cities are 500km apart or more.
