Hello, I have searched google and this forum but I am having trouble joining the 4 wide track curved pieces to the straight long rails. There does not seem to be a straight piece made, why I dont know. I have seen pics of trains running from curved to straight pieces but it seems to be a half of a stud off when I try to connect them. this is what I mean, any help would be appreciated. Thanks Scott ( had posted a picture but dont see it here)
