Hi Donald,
It's easy to change the top speed of a locomotive, at least I know how to do an F7 diesel.
1. Open content creator.
2. Click to "installed" tab.

13. Notice the eleven entries.
14. I changed the next to last entry from 45 to 70, and the last entry from 0 to 35.
15. Click "file", then "save", then close this window, and the next window, getting you back to
the "assets text view" window.
16. You MUST now commit, by right clicking on kuid 1:42004202, then click "edit" then click

Your F7 powered locomotives will now run above 75 MPH.
