The second part of the initial post in this thread turned out to be bad advise (ignore it), but the first part is a solid way to get your capital income to grow in the early game. It takes a lot of micro management to set things up initially, but once you've got your factories turned on/off as needed and buy orders placed for other necessities, you should see decent growth in your capital income.
With Russia it's important early game to also get railroads built leading to your coal producing regions, so it may take a while to get your economy humming, but it will eventually get easier to manage it.
For Russia early game I'd probably shoot for just a 5 point or less surplus in produced items as every extra dollar counts until you get your industry built up more.
