This question already has an answer here:
We have a question regarding Ticket To Ride. Can part of one train be used to fulfill two different destination routes? For example, my clever son completed his San Francisco-Atlanta “Destination Ticket” (17 bonus pts.). He then drew the Portland-Nashville “Destination Ticket” (also 17 bonus points) and decided this would be a cinch since he had already completed San Francisco to Atlanta. He simply added another 5 train cars, from San Francisco to Portland, and claimed another 17 bonus points for the Portland-Nashville ticket! I think he should not be allowed to do this, but should complete a whole separate train between Portland and Nashville to earn those 17 additional points. I may be reading the rules too quickly, but I don’t see where the rules explicitly address this one way or the other. Do you know if there is an “official” rule on this? Or is it up to people to determine this in their own house rules? Thanks for any tips you have!
