Phil,

What options do you have?

Klaus, Phil may not be able to answer your question since he writes he runs analog DC.  If it helps, I have the Roco item 62939 V100 in Ep. IV version numbered as 211-200 with factory-equipped ZIMO decoder.  In addition to the normal F0 "running lights on/off", it has F1 "cancel forward lights" and F2 "cancel rear lights".  As you write, these functions are especially useful for push-pull (Wendezug) operations.

Hope this helps
Tom
