Railcraft - Detector - Chest cart

[khorozm]

Hello everyone.
I am trying to set up a railway system that transport EU and Items.
At the terminals I have detectors switching the switch tracks to separate the EU carts from the item carts.
However I need detector for chest cart, the item detector doesn't work because it also detects the EU carts.

Now my temporary solution is to set the item detector to "not empty" and make sure my chest carts always have at least one item when they leave.
Is there actually a detector that detects chest cart but not anything else?

Thanks

Another way to do this would be to set up actual trains set to follow different routes via tickets.
