All About Marklin HO Model Track
Marklin has made at least 3 different types on HO train track with a metal roadbed: 1)) 3-Rail (aka 3600 series), 2)) Model Track (aka 3800-3900 series), and 3)) the very common “M” Track (aka “stud”.) These tracks have been made in various radii (size of concentric circles.) 3-Rail track and “M” Track curve pieces have very common radii of 360 mm and 437 mm. But the “Model Track” has the much LARGER radii of 536 mm and 586 mm. See table below:
·5100 Standard curve = 360 mm or 14.17 inch radius
·5200 Big radius curve = 437 mm or 17.22 inch radius
·3800 “Model” curve = 536 mm or 21.10 inch radius
·3900 “Model” curve = 586 mm or 23.07 inch radius
Very cool things about Marklin Model Track:
·Has much LARGER radii for more realistic layouts (it takes 16 pieces of curve track to make a full circle)
·Has plastic inserts between the metal roadbed and the train rails for reduced running noise
·The “sleepers” are black plastic and look more realistic than the sleepers of other Marklin metal track
·Model track has a studded center rail very similar to the common “M” track
·The 2 outer rails are electrically connected with 2 jumpers on each piece of track; these jumpers can be cut which make all 3 rails electrically isolated from each other, allowing 2 rail DC train operations
·Model track and "M" track can be connected to each other without any special transition pieces
·Model track sold for a few years (around 1953 thru 1956); it did not sell well and was discontinued. It is hard to find; commands a premium price
·Model Track has a slightly more yellowish color roadbed compared to “M” track
·The years that Model track was available were also the years that Marklin switched over from their old numbering system to a new “4-digit” numbering system. However, just as the new numbers were introduced (i.e., the 5040, 5050, 5056) the Model track was discontinued and few folks know the track by these newer numbers. For Model track, here are the corresponding numbers:
