Not quite finished yet but here's my current project. MTH SD50. I took some ideas from others as far as a "plate" to fill the pilot gap, but my own idea for the end sheets. I grind off all molded details then put thin plastic sheet over the face and add all the details such as the coupler pocket and rivets. Then add PSC MU hoses. I also redid the main electrical jumper from wire as the factory piece was just too small and this was a prominent feature on these. The rear is finished, the front just needs the 2 railings redone, then for a light weathering as these units were very new in the Chessie era.
