I got the update from Train Simulator 2015 to 2016 on Thursday. But I hardly use this program and got a gift from one of my son in the year of 2014. All I did is to leave the program in my computer. This past week I decided to try to simulate this program but find different between two programs -- MSTS and TS-2015. What I want to know is that how can I increase the speed of the player train? I did click and hold the wheel on my mouse to increase the speed but find that they don't go one a time to increase and notice that when I move the speed up and jump to about 8 to 10 mph. Is there a way to increase the speed limit just like a prototypical train also any keys on the keyboard to increase the speed limit? I am learning with this program.
