Quick informational on trains and smelting on site.
Was doing the math on my train system to see how much I could squeeze through raw vs smelted and worked out the numbers. Though I would share them as the percentage increase should roughly apply to all train networks.
100% All Raw ores and Oil in Tankers = 2.39 RPM
123.84% with Steel made on site Everything else raw and oil in Tankers. 2.96 RPM
192.42% with Everything pre smelted and oil in Tankers. 4.599 RPM
195.81% with Everything pre smelted and oil in Barrels 4.68 RPM
Just for fun I worked out barreling oil but leaving everything else raw.
101.2% with All raw ores and oil in Barrels 2.419 RPM
No real surprises, steel gives the biggest bump for the least effort and oil gives the least effect.
All the boring math stuff below in case anyone wants to check my numbers
Used a unidirectional rail network with a single exit rail and multiple entrance rails. So all I had to do was see how many trains I could get out the single exit rail to determine the maximum throughput of the network. Used rocket fuel.
Designed this rail network a while ago and messed up on the oil tankers I though they were only twice as heavy as a normal wagons instead of the three times weight they really are. This is why my oil tankers are 10:20 it was to keep ratio with the 6:24 cargo trains for acceleration purposes. However oil makes up only 2.5% of all the train movement so while they numbers may be a little off it won't be by much. (I'm not redesigning my entire oil network today)
Number are all based on a end game base with productivity modules used everywhere. I pulled all the numbers from the Factorio Calculator in below link.

440 trains (6L:24W) in a Time of 51:47 can exit my base
203.92661 wagons a minute
3.398776955 wagons a second
3.398776955 wagons a second (Fits 6797 raw ore a second)
All Raw with oil in tanker trains
Iron ore 1670, Copper ore 831, Coal 163, Stone 100, Oil 2251.
(1 ore = 31.25 oil so oil takes 72 ore space in train wagon terms for ease of calculation)
2836 resources a second for 1 RPM
2.39 RPM
100% Base
Steel smelted on site, all else raw
Steel 183, Iron ore 1036, Copper ore 831, Coal 163, Stone 100, Oil 2251.
For maths ease I am just going to half steel (91.5) that brings it in line with the ore numbers, oil still 31.25.
2252.75 resources a second for 1 RPM
2.96 RPM
123.84%
Everything pre smelted, oil in tanker trains(3.398776955 wagons a second fits 13595 smelted)
Iron plate 1245, Copper plate 997, Steel 183, Coal 163, Brick 60, Oil 2251.
(Coal Doubled for math reasons 326)
(1 plate = 15.625 oil so takes 145 space in Plate terms for ease of calculation)
2956 resources a sec for 1 RPM
4.599 RPM
192.42%
Everything pre smelted, oil put in barrels. (3.398776955 wagons a second fits 13595)
Iron plate 1245, Copper plate 997, Steel 183, Coal 163, Brick 60, Oil 9.004 Barrels.
(Coal Doubled for math reasons 326)
(Rounded up to 9.1 barrels for ease of use so it equals 91 plate space)
2902 resources a sec for 1 RPM
4.68 RPM
195.81%
For kicks just oil in Barrels with everything else raw.
Iron ore 1670, Copper ore 831, Coal 163, Stone 100, Oil 2251.
(Rounded up to 9.1 barrels for ease of use so it equals 45.5 ore space.
2809.5 resources a second for 1 RPM
2.419 RPM
101.2%
Site smelting and Train throughput.
Re: Site smelting and Train throughput.
Was about to be expected... The increased throughput comes solely from the doubled stack size / compression for Plates in comparison to Raw Ore which explains the near 200% throughput.
But the downside for smelting on site is the increased need for infrastructure in the mining outposts... which in my opinion is such a big downside that it's not really worth the doubled train throughput (which is not really a bottleneck in my base anyways). I rather have one big centralized (load-balanced smart-)smelting area that never moves than 20 distributed ones all over the place which eventually become useless one after another and only forces me to move even more items... as if building/cleaning outposts wasn't an ugly chore already.
