How possible to orient Particles along travel direction? (rotation did not work)

[Alexx31]

Hello,
I have a scene, where randomly rotated particles should spawn new particles.
But those spawned particles need to be aligned to the travel direction.
I tried 2 different approaches but did not succeed.

I used Pyramids to see the direction clearly and they were randomly rotated.

How can I achieve this?

Thanks
