Hello,

I have the Roco BLS Re 420 (Re 4/4II) with OEM ESU decoder (69844) as well as the Liliput (ex-Swiss Express) coaches, which includes the pilot coach L388895 with a ESU decoder for the light functions.

The Roco Re 420.5 comes with coupling on one end only, which is the end without the pantograph. I would like to run the train with the pantograph end in front, which is coincidentally slider forward. The train would be coupled to the end which does not have the pantograph.

The problem is that no matter what I do, the red light on the pilot coach is on when the lok is pushing and the pilot coach is at the front and the white (ok, yellow) lights are on when the lok is pulling and the pilot coach is at the rear. Is there a way to reverse the lighting function on the pilot coach without having to rewire it in reverse?
I have not yet checked my Roco Re 4/4IIs and Liliput coaches in the original Swiss Express livery to see if they have the same problem, but I will do so tonight.

Has anybody else experienced the same problem with this or another consist equipped with two decoders?

UPDATE: I tested the consist with my Maerklin BLS Re 465 (39606) and concluded that the LED contacts in the pilot coach are indeed reversed. I have found that the same problem exists with the SBB Swiss Express liveried L388885 pilot coach as well.

Hi, Mike,
I've reversed the direction of some of my Roco locos using CV 29, bit 0.

This would lead to your loco pushing the train when moving "forward" and pulling when moving "reverse".
I don't recall changing the function mapping to make this work.

Maybe CV 29 bit 0 would also do the trick if applied to the Liliput coach.
