Wide Radius Left Curved Turnout. A long-standing wish of Märklin fans is being fulfilled with the wide radius curved turnouts. Prototypical track plans are now no longer a problem. Märklin is thereby setting a new standard in turnout geometry in which the conception of elegant track patterns reaches new dimensions. Inner curve: R3 = 515 mm / 20-1/4 / 30°. Outer curve: 30° with a parallel curve spacing of 64 mm / 2-1/16. Hand lever included. Two (2) each 24315 track are required on the inner and outer curve of the turnout. A roadbed piece to fit here is included. The 74491 electric turnout mechanism, the 74461 digital decoder, and the 74470 turnout lanterns can be installed on this turnout.
