Part of my layout under construction is this shop. The ALCO PA (Maerklin = TRIX) is part of my museum route from here to downtown. This shop is also home for my Maerklin BigBoy. Only this short track is build as a 3-rail track. All other is 2-rail DCC. All tracks are the same material (Pilz Tillig ELITE Code 80). For the 3-rail track I add a special metal ribbon which is placed under the 2-rail track. Only the short and small tips are looking over the railroad ties.
