This is Will Everett. He's come up to Craigellachie to meet his father who’s been working on the railway for the better part of three years. (Will actually hooked a ride up into the mountains with Van Horne and the other CPR dignitaries in their private train.)
And here's a secret about the Last Spike.
It isn't Donald Smith who drives it.
You won't find it in any official photos. But after Smith bungles the first attempt, Van Horne offers the hammer to Will. The railway belongs to a new generation and a new century, says Van Horne, and Will should be the one to drive the spike home. He does so.
The spike is solid gold.
