newest version seems increase the max speed much more than before, but trains speed up time is much longer than before( same setting MAX speed at 2000 in old version), old version from stop to top speed only need like 3-5 sec, but now is much slower and take much more time like 10 sec or more.
So how to made the speed up time more shorter like before?
And looks like newest version use standard cargo size 40 , but in the game cargo size change to 16, is this a bug? and oil cargo standard 25k, in the game is 6.2m..............

well think of it this way in space when you wish to go near the speed of light it takes more energy to increase your speed and @DellAquila there could be a balance if it is not implemented
