"ok i was installed this train, the SP AC-12 Cab Forward, it was basically from a youtube video i founded, i glad i downloaded it, but when i checked on the train itself after i downloaded it last night. heres what you are seeing. see how the first one was meant to have a cylinder?, it was suppose to, and idk why it didin't appear, but that didin't end there. not only the 2nd one is missing a cylinder too. but do you see that it has a wheel on there. that is meant to be for the stand with a coupler to the tender, heres the link [drive.google.com]i originally got, and if you know how to fix this. tell me please"
