Set Max Speed to Command Problem

[foristellsteam]

When I use the "Set Max Speed to" command <kuid2:450022:90001:2>, the AI trains travel a little below the limit I have set. For example, I have a train set to 70 MPH, but he will only go to about 65 MPH. Is there a workaround for this? Not the biggest deal in the world, I know.

The obvious question to ask is what is the maximum allowed speed for that particular loco asset? Some locos (and rolling stock assets) have a maximum speed built into their config.txt file. The tag "max_permitted_speed-60850" sets the maximum allowed speed for that rolling stock asset.

I have a route where the loco has a maximum set speed of 47mph and it will not exceed that speed for track with a speed limit of 50mph (or greater) or when the Set Max Speed command is set to a higher speed.

PS: Don't forget that there are two versions of the Set Max Speed To driver command - one for MPH and the other for KM/H

The top speed for the loco is 70 MPH. I tested the train without the speed limit command, and he went the full 70 MPH. Also, when I set the top speed to 50 mph, it will still go a few MPH lower than the command.

Yes, I did make sure I was using the MPH version of it

Does the same thing happen to other types of locos or is it just specific to this loco?

I will have to do some further testing. I will post the results once I am finished

Does the loco have the max-speed permitted tag in its config somewhere set to 65?

I didn't see that tag in the config

Upon further testing, the AI can reach the set max speed when it is the locomotive alone. This is quite the pickle I find myself in

It is possible that one of the wagons in the consist has its Max speed tag set to 65mph.

Another issue with this command is that whenever you leave the session it no longer works. Whenever you stop the train, it must be added back again. Hopefully this will be fixed.
