Blueprint train unloading

[nuhll]

Hi,
someone has a nice blueprint for unload trains maybe with some waiting bays? 2-3?

Unloading with belts ofc. Currently i unload with robots, but i think its too much energy waste..

There are a TON of different designs depending on what you want. Usually you'll unload from the train to chests, then from chests to belts. This unloads the train faster so it can continue on its route, and the next train can enter, while ensuring that there is a steady stream of resource going onto the belts.

Then it depends on what you want to do with the resource. Merge it to 2 lanes? 4? Each side of a train carriage unloads onto three belts (one inserter per belt lane) and you can use splitters to balance them however you want from there. If size is an issue you can sacrifice balance, or if throughput is priority then balance away.

What's the point of Factorio if you're just going to rip off everyone else's designs? ^^

I dont care. I looked on the forums and searched for it, but found nothing but outdated things.

If i have fun in factorio copy other things, then i do it

Should be able to handle blue belt 2 or 3 are okay. balanced if possible. atleast 2 or 3 waiting bays for trains. train -> inserter -> chest -> inserter -> belt

*shrug* suit yourself, there's a bunch of designs here

And where excatly there is a Blueprint?

Most people don't play with the blueprint strings mod, especially now achievements only work in vanilla. Come 0.15 there may be vanilla blueprint serialisation but until then you'll just have to build it yourself =P

[nuhll]

Yeah, seems like i have to do that. For everything you find blueprints except unloading

Achievements were introduced in 0.13 along with stack inserters and new circuit stuff that changed how we unload trains so yeah I'm not really surprised at that =P

The problem with train station blueprints that there's simply too many variables.

The length of the train varies, and because of the odd number of spaces that each locomotive/car uses, combined with the 2x2 spacing of rails, you can't just shift stuff left or right and expect it to automatically line up properly, so you have to decide on a specific train configuration. How deep of a waiting queue do you need, and which direction has the necessary open space? Your inserter setup will vary depending on what kind of throughput you need for the cargo - do you need 3 compressed blue belts coming off each car, or is one yellow belt more than enough? Do you need/want chest buffers? Is it important for the cars to be unloaded at the same rate? Do you need refuelling at the station, or is that handled elsewhere on the route?

Those are all variables that will alter how the station is designed.

Here is a thread I was somewhat involved in where some examples of train loading and unloading were bandied about, you could try them. I am pretty sure they only work horizontally, not vertically, but as long as you work around that limitation they are pretty good. They are not blueprints, only images, but they are not difficult to copy and then you can make your own blueprints for them.

no blueprint needed for this one. two belts forming a T. connect inserters unloading the chests together & have Mode of operation, read hand contents (Hold), * = 0
this cuts out the need for a ton of splitters. all the chests get unloaded evenly. simple small footprint. combine sides/cars as needed with a splitter.

excatly what im using atm...

[Deadly-Bagel]

Just a note, all carriages are unloaded evenly but the chests are not. The 'inner' chests, closer to the centre where the belts merge, will not be unloaded until the 'outer' chests are empty because there is no room on the belt. This will slow the unloading of the train by maybe half, but it will still only take a few seconds and in most cases won't cause any real problems.

the method i showed, and use doesn't allow the inserters to grab anything untill they have all dropped what they are holding.
