White Pass and Yukon- Lake Bennett Run

I just finished watching the PBS presentation on the White Pass and Yukon. It was filmed in 1998 or 1999, apparently. The portion of the show that I found most interesting was the railbus portion from Fraser, BC to Lake Bennett. This railbus appears very similar to the D&SNG railbus. Is it the same rail vehicle perhaps? Any comments from John Bush would be welcomed.
The Lake Bennett depot appears to be beautifully restored.
Does WP&Y offer any other service to Lake Bennett now aside from the Railbus?
I wanted to go to Alaska this summer but didn't make it. Maybe next year.
