I have added two passenger coaches to my Märklin Metallbaukasten Adler 1002 modified for use on G gauge track. Currently I have made open coaches, as I saw some pictures of these but may cover them at a later stage. I have to thank Georg Eiermann for sending me the detailed plans of this. Märklin had issued a special edition of this locomotive, I was originally disappointed that this has wheels inside the body instead of outside the boiler as in the original. However, I thought I could modify it for use on G gauge. The locomotive draws current from the track so the wheels have to be insulated from each other. This was done by using plastic flanged wheels p/n 10336. I also added the 1022 motor to run it after gearing it down. I had to make flanged wheels using Meccano 146a discs for the front and rear wheels ( Märklin 10395 9.5 cm) and also for the tender. The middle wheels of the locomotive, 19.5 cm. 11095 were doubled to create a groove for the track. As my track has sharp curves I had to articulate the rear wheels. I am now using the 10365 wheels for the tender along with a 19b pulley split in half to form a flanged wheel.
