And it was never said that Doc went straight to 1931 with the DeLorean. In fact: "[That DeLorean] is, for all intents and purposes, the exact same machine. With a few minor bells and whistles added over the years, of course."
Remember in part 2 when marty is locked in biffs garage? Doc rides a bike there because he does not want to have the delorean seen in live daylight. The delorean is never taken out by doc in live daylight prior to 1985 and only flyes in iive daylight outside of 2015 in the 1985 to 2015 part.
Not sure how he finds out that griff steals the delorean in 2025 (maybe he sees him) but the time train would not have been out of place in the future.
This is what happens when you assay to make sense out of nonsense. We all know the flying Delorean was intended as a joke but was then entertained as reality. This is the very reason the time train isn't in the game. It's a joke reference to a joke; an indication that there won't be a continuation of BTTF because it's just too risible, impractical and, ultimately, a step too far.
But joke or not, the time train happened and is now part of the bttf plot. Plus doc does need a way to get to 2025 to recover the delorean.
4 episodes left; we'll either get a reference to the train if not see it.
