ive been trying to do this for the past 10-20 mins' and well-there is no bar that moves to switch the track. i asked ai and looked at what the videos talk about but i couldnt find the awnser. i need help! i am using a costom made sd40t-2 that the base sd40-2 was made by a person that makes base trains so you can dupe them blah blah blah all that stuff and i thought that the switch came with it or it was just invisable
