The rail system is close to the same, but the detector rail is not being activated on one side (as indicated by one being lit up and the other not being). The system is around the same on both sides I repeat so I do not know what is the problem with this, but if one side seems to be working, why not the other? When it goes uphill, it stops there and the piston blocks it; however, the piston blocks it the same for both side but does not activate the rail equally. If there needs to be more information on what I am building, I can provide the scenario but it is regrettable it does not work. Let me know if you can look into it.
