In MSTS MaxVelocity ( 60mph ) was included in eng files as it was needed to calculate physics behaviour. The number used to give the required performance was not always directly related to either the permitted or achieved maximum speed.
As far as I am aware this is no longer required as a physics input for locomotives ( steam diesel or electric ) that have Open Rails physics, and is not required in wag files.
The current way to set the maximum speed of a particular train (in activity mode or explore route) is to use the lines in the consist file.
So for a train allowed to travel at 100 mph we might have MaxVelocity ( 44.7 0.75 ) in the con file and this will also show as the maximum speed in the track monitor where line speed permits, if the train now attaches another vehicle, restricted to 75 mph the MaxVelocity in the consist file does not change so if the line speed permits the track monitor window will still show 100 mph.
One way to deal with this might be to include MaxVelocity ( 75mph ) or MaxVelocity ( 120kmh ) in the wagon section of eng and wag files. Then the lowest maximum speed of any vehicle in any consist would set the maximum speed for the train shown in the track monitor.

Sounds like a reasonable idea; MaxVelocity does not work when using traction curves for some reason...

And designing traction curves which take into account such things is close to impossible, at least on a grander scheme...

In regards to this subject, especially unfitted freight wagons in the UK, we could implement wagon/consist speed limits in a manner that overrides all higher speed limits on the route, and enforces that lower limit until the wagon(s) in question are uncoupled.

For example, if you have an unfitted freight consist that in the real world would be limited to say, 25 mph, then the game would enforce the maximum speed limit of 25 mph for this player consist, even though the max track speed on that section of line may be much higher than that, and if the player consist exceeds 25, the overspeed warning is triggered. Likewise the track monitor would state the speed limit as no higher than 25, even if the actual route speed limit is higher.

Yes, similar when pulling 2 axle/ 4 axle wagons in the same train as the 2 axle cars cannot go this fast relative to the bogie cars.

You can already do this by designating a max speed in the consist files.

All my consists for Thames - Trent route are set to realistic speeds for steam era working.

Regardless of max line speed, my unfitted mineral consists. Never exceed 30mph or lower when stipulated by a PSR.

G'day Dogbert,

Do you have any specific settings you could reveal for us please, as I can't find any info on what the two figures in the MaxVelocity parameter actually represent.

Regards, Brian
