Marklin 24624 - C-Track Double slip switch, 24.3 degrees
188.3 mm / 7-13/32" / 24.3°. Comes with electric mechanism and lighted double slip switch lantern.
Charlie's Tip: Can be retrofitted with a 74462 digital decoder. It only needs one. The older style 74460 or 74461 will also work.
Of course you can also use a Marklin 60832 or other K-83 or M-83 style decoder. In that case you will run wiring from the decoder to the turnout motor.
