The Powerline model comes with an Atlas style decoder layout. The Powerline decoder and twin capacitors (where fitted) need to be removed to make way for a hard-wired ESU LokSound V4.0 micro decoder (pictured below). The red decoder wire goes to the RHS pickups of the model (pictured on the top side of the photo), the black decoder wire goes to the LHS pickups (pictured on the lower side of the photo). The orange decoder wire goes to the red motor wire, the grey decoder wire goes to the black motor wire. The lighting works such that the headlight and white markers at the short hood end and the red markers at the long hood end are powered in the forward direction. The reverse occurs with the long hood leading. To house a 16x25 mm speaker in the model, the end of the top motor clamp plate is removed. Then 0.5 mm styrene sheet is used to separate the front of the speaker from the back, which enables louder, richer sound.
