very well said--&quot;no wall clock time&quot; as you put it. I&#x27;ve done the Euston&#x2F;Kings Cross -&gt; Inverness and E&#x2F;KC -&gt; Ft William many times and i loved it. Inverness has an airport and it&#x27;s only an up-and-down flight, but what an ass ache to travel to gatwick to catch this flight rather than a 15-minute tube ride to the train station.
