Nice idea! A thing that should have been availiable since years...
But I miss three things on your comparasion:
It would be very interesting to see what happens if the incomming cash is invested in more vehicles. The point is that I believe passenger services have a much better performance - compared to coal lines - if the connected cities are able to generate enough passengers. Also much depends on the size of the cities.
It would be very interesting indeed. The reason I did not to this in this test is that I simply did not have the time; and, by not investing extra cash the comparison becomes more accurate for one line only, even if it might not describe actual game-play as accurately. This is definitely something that should be investigate.
For me it seems you play with the normal tt airplane speed, which is reduced 4 times compared to the real airplanes. AV8 was designed after this limitation had been dropped on TTDP and it was never designed to be played with slowed down airplanes. Especially when driving on the ground, early airplanes in AV8 are extremely slow, if this parameter isn't changed. If I remember right, I ran a short testing game once and on that game it was no problem to run early airplanes of AV8 like the Farman Goliath profitable.
It is true, I use 1/4th of the original speed, and I agree completely with you. This is actually not the first investigation of this kind that I made. I did one earlier, just for personal use, but it was not as exact (different starting years, construction finishing mid-year and so forth). My settings for that test was fairly different, one of the differences being that I did not reduce the speeds with 1/4. These settings did indeed prove to be favourable for aircrafts, including very early ones. The reason I used other settings this time is that I wanted this comparison to be relevant for hard and competitive multi-player games. That is why I asked this question
I miss ships! No joke! Using ships on a coal line, the investments into infrastructure are extremely low as you don't need to lay tracks or roads. For the money you've saved you can buy another vessel very soon. It's a long time ago I experimented with ships because it's a little bit boring to play with them, but as far as I remember they are comparable too a good coal-/passenger-line.
Again, the answer is similar to the answer above. Because of the early starting year (1920) there were no ships available. In my earlier comparison ships proved very profitable and also had the advantage of minimal construction time. The only problem is that it is quite often hard to find good routes for the ships if you have only low to medium quantity of water.
Thank you for all your input DonRazzi!
