Not long. There's basically a crane for each car that picks up all the things and transfers it with an animation. I think people have timed it to be like 20 seconds. The train is by far the fastest way to move stuff. Each car can hold 64 stacks (I think it was) and it moves at 120 kph so long as the rail is long enough for it to reach it. Power fluctuates a lot though as it climbs hills.
Oil refineries are huge and, depending on production type, you'll have 5 or 10 refineries per oil extractor.
One Mk3 miner on pure coal can drive 52 coal generators. There's a table on here:
The Coal Generator is a power generator building that generates power by burning Coal, Compacted Coal or Petroleum Coke and Water. It is the first fully automated power source the pioneer has access to and also the first source to use a mined resource. One Coal Generator produces 75 MW at...

300 m3 of oil can produce enough fuel for 13.333 fuel generators.
The Fuel Generator is a power generator building that generates power by burning Fuel, Turbofuel or Liquid Biofuel. At 100% clock speed, one Fuel Generator produces 150 MW. This will use 12 m3/min of Fuel or Liquid Biofuel, or 4.5 m3/min of Turbofuel. Note: Italic values are based on...

The problem with refineries in general is dealing with their byproducts, especially heavy residual fuel. To deal with the heavy residual fuel, I ended up making my 30 refinery fuel distillation facility (bottled water + heavy residual fuel = canned fuel - can = fuel for generators). Problem is the thing shuts down which shuts down the upstream producers if heavy residual fuel backs up. As I said before, the lower the power consumption, the more plastic it burns through for cans which get recycled to get rid of the surplus fuel. It's a less-than-ideal solution because the supercomputer factory needs so much plastic; however, the alternative is petroleum coke which is kind of useless (inferior to coal in every way).
Hmm, petroleum coke is actually better than the normal recipe for steel ingots (iron ore + coal = steel ingot -> iron ore + petroleum coke = 1.33 steel ingot) but you need to unlock the alternative first:
Petroleum Coke is a fuel item distilled from Heavy Oil Residue. As the AWESOME Sink does not accept fluids, converting Heavy Oil Residue into Coke is one way to sink it, solving the fluid deadlock problem in the early petrochemical setup. It was formerly used in the production of Aluminum Scrap...

Can also make circuit boards exclusively from oil (oil -> rubber -> heavy residual fuel -> petroleum coke | rubber + petroleum coke = circuit board). I don't know about the numbers though. Might be short on rubber or might be short on petroleum coke.
