Model Decoder
Installation of T1 decoder in an older electric locomotive E499 (TT scale) produced in German Democratic Republic by BTTB. 
The model was produced when DCC was not even known so electric installation have to be changed. Motor and light has to be disconnected from the electrical pickup, then wires of the decoder should be connected to pickup, motor and light. The model has enough space for T1, M1 or MC2 could be of course installed as well. After some changes in CVs model is running very well.
