Hello
I just made my first figure 8 with a standard kit and some extra track.  When I try to get the train to go, it keeps stopping on the straight track next to the intersection.  I cleaned it and switched it out.  Nothing seems to work.  Any track I put  there akes it stop.  Once the train gets past the bad place, it goes fine.  I am not sure what to do and Christmas is coming.

Thank you for any help
