Problem with uneven cargo train distribution.

[MaxxPower]

I have a city of 2 big R-C-O blocks, which are supplied by train from a dedicated industry block.

Both blocks have almost the same number of residential and commercial buildings.
The industry block can only be left by cargo train, metro, cargo ship or on foot. No trucks or cargo vans can leave the industrial block.
This means that all city-internal cargo traffic happens by train.
Each of the big R-C-O blocks has 2 dedicated cargo train stations for the local commercial buildings.
These stations are isolated from outside connections. They only go to the industry block and nowhere else.

My problem is, that the right city block (the one near the industry block) receives almost twice as many trains as the left one.
As a result, there are lots of vans delivering goods from the right train stations to the left commercial buildings. (blue arrows)
This causes traffic jams at the right train stations, while there is almost no traffic at the left stations.

Any idea how to fix this without building another industry block on the other side of the city?

I'm just tossing out an idea here as I don't have much experience with the train systems so take it for what it's worth

I would imagine that the industry trains are selecting the closest station as their preferred stop for the cargo as they have, for whatever reason, calculated that the roads to the second block are faster. The traffic-pathing system is still a mystery to me.

Perhaps, instead of having a track switch right before the first station, build the track so that it goes to the the center of the highway junctions and then split the track there to reach the destination? I don't imagine it will be very efficient in terms of track layout and cost however.

Good luck with this issue, hopefully someone else will offer a more efficient solution.

You might also try disabling the on-ramps closest to your right-side cargo stations. The path of least-resistance is not the choice, but shortest distance.
So moving the rail junction/split would likely help on that end as well.

Thanks, will try both.

Splitting the tracks further down to the left worked nicely. Now i have almost perfect 50/50 distribution and much fewer vans on the highway.
Tyvm!
