trains will not stop and wait


New member
just a small question... in my layout i have a y going east and west with a leg going south, this leg is a train track going over a lift bridge with a ship track going east and west. my question is how do i plase signals to control the train while a ship passes under the bridge. i have tried a diamond cross wich didn't work, then triggers for the signals. but still the train goes across the bridge when a ship goes under it. my version is 2006. any help will be appreciated. thankyou....travelingman
