Hello Kevin,

welcome to this forum.

Concerning your question on decals, there is the usual answer: it all depends on...
... what you want to do.
If I understand you correctly you want to repaint and afterwords reletter the locos, here especially the 194 and E69.

Paint scemes vary for electric engines vary from era II to era III.
The E94 was darkgreen-grey during era II. You may have a look at Andreas Langes web site: http://www.rbd-breslau.de/12-elloks/elektrische_lokomotiven_einsatz.html and http://www.rbd-breslau.de/12-elloks/elektrische_lokomotiven_malgehabt.html.
In era III the loco was repainted to (first) bottle green and (later) chromium oxide green.
For the E69 during era II the same applies as to the E94. In era III the things are a bit more difficult. Here it depends on which E69 you want to repaint. E69 03 and E69 05 were repainted to red, whereas the other three locos got the bottle green and later chromium oxide green livery.
Decals can best be found at Gassner's: http://www.gassner-beschriftungen.de/ (German text).

I hope this will help a little as a kind of start-up. If there are any more questions, feel free to ask them here.

Martin
