Actually, it's an easy calculation, and you don't even have to be concerned about the length of the trip. Here's how to do it.

Let's use Joyful 2nd Class for our example. This wagon carries 420 passengers and gives +120% profit. Therefore, the electric train will generate more profit.
 * Steam:
 * 420 x 120% = 504 (calculate wagon bonus)
 * 420 + 504 = 924 (add wagon bonus)
 * 924 x 75% = 693 (calculate set bonus)
 * 924 + 693 = 1,617 (add set bonus)
 * This wagon will return on a 10-minute local run.
 * Electric:
 * 420 x 120% = 504 (calculate wagon bonus)
 * 420 + 504 = 924 (add wagon bonus)
 * 924 x 30% = 277.2 -> round to 277 (calculate set bonus)
 * 924 + 277 = 1,201 (add set bonus)
 * 1,201 x 2 = 2,402 (locomotive bonus)
 * This wagon will return on a 10-minute local run.

However, that's not the only thing to consider. The 90-power steamer is the biggest locomotive in the game. It could come in handy for contractors, who often request hundreds of wagons to complete contracts. If that doesn't matter to you, then go for the electric for the profit.
