A cargo wagon holds 30 items, barrels stack to 10, and hold 25 units of oil. So a cargo wagon holds 7,500 oil. A single chest, at 48 stacks, is even better for holding that oil than storage tanks. A stack inserter, pulling even just 4 units at a time, is around 150-200 fluid moved a second. I admit to not understanding fluid flow, but this thread (viewtopic.php?f=5&t=6066) says 150 fluid/second is max length 4 pipes. At zero (storage tank next to pump next to wagon?), the same speed can be reached with multiple inserters or higher upgraded inserters.
Assuming we get barrelized everything: a cargo wagon can reserve slots for various fluids, and filter inserters can pull specifics. A fluid wagon is dedicated in-use and station-stop.
Is it just because the fluid wagon is cool? Because I could believe it.
More or less because its a "set-and-forget" type of solution. Barelling up requires infrastructure, and has constant energy drain, requires space and produces pollution. What is more important, you have to setup an overkill filling setup in the beginning, since you have a high output on pumpjacks, which later becomes totally overkill as the oil source gets closer to the 0.1/s minimum. Right now the set-and-forget solution is running a pipeline together with you rail system so you simply connect to the main pipe on demand when you encounter oil sources, which does not really add anything but a needless iron consumption on a shitton of underground pipes.
An oil wagon would basically encourage a setup where you put down a pumpjack, a tank, and a train which drives in circles around the outpost, collecting the oil.
