Description of the Bug
Items inside the chestcart doesn't get unload with itemunloader.
The itemunloader won't emit a redstonesignal for a locking track.

To Reproduce
Steps to reproduce the behavior:

1. Place block/item-unloader
2. Let a chestcart move above it
3. It won't get locked above unloader and no items get unloaded

Expected behavior
Chestchart should stop above the unloader, because of the locking track, and get unloaded

Screenshots

Environment

• Railcraft 12.0.0-alpha-7
• forge-14.23.5.2772

Well, the track only locks if it does not receive a redstone signal. Your description is unclear.

i tested a bit more and the problem is not the track. The itemunloader doesn't recognise items inside the cart. It directly emits a redstonesignal if a chestcart is above it, even if there are items inside.

Try adding a filter for chest carts and change the unloader's mode.

I did. I put a stack of dirt inside the cart and set the filter with dirt.

Can confirm what Texas said. Appears to be working as intended in alpha 9

In alpha 9, both the item unloader and the advanced item unloader are working via the chest cart. Used locking track on top on one or both. unloaded straight away.
