Märklin "Länderbahn" 3029 
 

The original: Lok "Anna"

A new project to convert a Märklin 3029 to digital with all the bells and whistles.

The loco plastic body was in a bad shape, buffer and smoke stack was broken off.

First, room is needed for the smoke unit. With the Dremel tool a very easy job.
 

The replacement for the broken smoke stack will be a Seuthe smoke generator.

New metal buffers (Puffer).
 

Next is the frame, here is some milling necessary to install a Telex coupler,
a digital decoder and speaker for the sound.

The air pressure tank was cut in half to make room for the Telex coupler.

More milling in the front of the frame for the decoder and one speaker.

A contact spring will provide a good connection from the rail to the frame.

After all the milling the frame was painted.

5 pole motor with the modification of the left lower mounting screw.
The motor has to be removed again for the installation of ball bearings
on both sides of the armature shaft. The running noise of the motor is
very high for this small engine, especially while shunting at a low speed.

This ball bearing can rotate up to over 100,000 RPM

Ball bearing installed in the brush holder plate

Here are two contact springs on both front axles to provide better connectivity.

Underneath the brass bracket are two contact springs on both front axles.
