Delta 60760 f0 = front light, change with direction
f3 = interior light (unofficial output)
f4 = acc/brake delay cancel

I will concider to install Märklin's new 60962 mLD decoders in these locomotives, to be able to adjust the maximum speed to the prototypically correct 45 km/h.  The running characteristics will be even better.
