[0.15.36] Train cars can have rail mined from under them

Post by Cribbit »

Not sure if this is a bug or not but figured it was worth reporting before I started taking too much advantage of it.

Picture describes it best.

Each car is in a position where if removed it could not be placed again as there are only 2 pieces of track under them. This is done by placing the car as far to the edge of 3 tracks as possible then mining the far piece of track. This is where I believe the glitch lies if this is a glitch, whether or not that piece of track should be mineable.

You can keep doing this as far as you want. All four of the inserters between each pair of cars will move items between the cars in either direction. This 4 inserter state is easily possible between just 2 cars by edge placing two trains towards each other, it is only extensible to many traincars by using the ability to mine away the far rail.

Thanks for the report. While it may look weird this isn't breaking anything and if the rails are minable they're not required for the cargo wagon to work correctly. So with that in mind I'm going to say we won't change anything and leave it as it is.

Yay. After some testing there are some cool things I can do with this and they require having quad stack inserters between the carts.

Except that it turns out if two inserters start going at the same time but the target doesn't have room for the 2nd one then the 2nd inserter sits waiting for room. Time for circuitry! (or is this a bug? would be nice if the inserter didn't jam, but I'm guessing this one's intended for sure)

EDIT: Huh, inserters will grab and wait to insert on a full target. Never knew that. Makes sense, I guess. I really hope I can solve this with circuitry. It sucks that enable/disable doesn't make an inserter return its held items but I understand why that has to be the case.

Placing cars on two tracks isn't impossible at all. You just have to be very precise as there's only about 1-2 pixels where it works.

whoooaaaaaaaaa


This solves everything! I was having issues where as soon as I placed a train I could no longer set filters/wiring on the filter inserters underneath them. The deadlock on full slots still causes some problems but it's impossible to get around if I can't put circuitry.

Also if you can still place them on two tracks then I definitely don't think this is a glitch. I only reported this because I thought I was putting a wagon into a state it couldn't be by just placing.
