As promised, I wrote a mod for railway logistics from scratch.
The main emphasis was placed on the possibility of multi-commodity logistics. I myself tried to play with my mod in both the vanilla version and in SE - it works great. There are some minor flaws, but it does not affect the playability, I will correct it over time.
If there is interest in the mod, I will add support for SE space elevators.

Re: yet another Rail Logistics Dispatcher
What a coincidence, we seemed to have had the same mod idea at the same time. Nice job!
