Using Optional to prevent NullPointers In TrainWrecks

I don't usually post or comment on StackOverflow, but I thought I'd give it a stab.

I was thinking of using Optional.ofNullable to be able to "map" my way out of a sequence of NullPointers more or less cleanly, but I failed to get something nice.

I really like the solution give in the Answer, it's not something that would naturally occur to me.
