Steam Br 114 Acceleration Problem And Pressure Indicator

The BR 114 still has problems, the brake pressure indicator still only shows 4.5 bar and there is an error in the acceleration.
If you have the traction control set to a value above 50%, the locomotive only accelerates for a very short time and then stops, and then it continues like this. If you have the traction control set to below 50%, the locomotive accelerates normally but very slowly.
Please solve the problem so that you can also set the traction control higher.

 

Well, then there are the lights that need to be turned on from the rear cab.
