Here’s some timely video I came across on YouTube taken in 1994 from the southbound regular passenger train, starting from the longest (middle) of the three trestles at Oba Lake. Video begins with showing the train crossing the wooden trestles on Oba Lake at mile 212.7 and 211.9, then has a fair bit of running between Oba Lake and Franz, with several other small lakes and at least one siding (at Hilda or Scully) seen before arriving at Franz near the end of the video. The southbound approach signal is seen before arriving at the Franz diamond.
In the video, you can see that the long trestle at mile 212.7 was still the original wood trestle in 1994. This bridge was replaced by a trestle with steel pilings sometime in the late 1990s or early 2000s.
Here again is the modern trestle and widened approach alignment where you can see the track has been moved to the right:
