Märklin 2846, CFL 455
Conversion parts:
For the 2846 I used the conversion set 60901. A rather simple and straight
forward conversion. There are no needs for any modification to any
parts, except for the lamp holder to the common bulb for both front and rear
lights. I have replaced the couplers with close couplers from Märklin
7205, 40 couplers for cars and 10 for locomotives.
Decoder:
The decoder is installed at the same place as the original reversing unit.
It is installed in the holder 258820.

Motor:
Installation of the motor itself is simple. After removing all the existing
parts (motor, reversing unit, lamp etc.), clean the chassis and make sure
that everything (transmission and wheels etc.) is turning smoothly. Install the new
motor, firstly without the brushes. Check once more that everything revolves effortless. Install the brushes.

Lamp:
The original lamp position in the locomotive is still used, now in a new
holder, to use the 610080 bulb. See the above photos.
The interior light is a 28 Volt T1 bulb connected to f1. The original
lamp bottom contact is soldered to one if the lamp holder pin and connected to
the orange wire from the decoder.
