White Pass and Yukon

Been spending the last few days going through Borries site about the WP&Y. The site is greatly improved over what it was just a year or so ago.
I have noticed though a couple of things and I may be asking what are dumb questions, but here we go?
I notice that the Engine house in Whitehorse is going to be (hopefully) moved in the near future.
But, is WP&Y going to leave the tracks through to Whitehorse or is the scrapper on the horizon? I understand that trains now only go as far as Bennett. So, I just thought I would ask...
Also, WP&Y bought back some of the old Locos from South America, what is the purpose of all the power? Do they run multiple trains during the tourist season?
If I missed the earlier posts, sorry, just thought I would ask.
Thanks
