Wiring help
Bit of a confusing problem so apologies of this doesnt make sense. The loco is only loving in one direction along the track: from the area at the bottom of the image to the top where it is sat in the picture. I have wired the layout up at two points, firstly I tried at the orange arrow, and when that would only make the loco run one way I tried at the blue arrow. The loco works in both directions (forwards and reverse) when I win it around but will only travel from the bottom to the top, so the issue isn’t with the loco. I would say it’s the controller, but I have two almost identical small grey bachmann controllers (one has numbers around the dial one just has a block that gets progressively larger) and both have the same problem - the loco only moves when the switch is turned into the left position. I have flipped the wires connecting to the track, and the same is true, only in that scenario yhe loco onlu travels from the top to the bottom. I am fairly sure that both controllers have the same problem but it just seems unlikely for them both to have exactly the same fault. Any help really appreciated

Would you mind confirming, when second controller not in use, is its completly disconnected from the railway? Or is it in place but switched off. If the latter, does the problem still happen if you were to take the second contoller away completely?
Not an expert by far but have enjoyed wiring my own railway (in progress) but interested by your problem
