Speed Limit in F4 display

[rlkimbal]

In my F4 display, when the speed limit exceeds 70 mph, 74 mph is displayed in the upper section of the F4 display. The correct speed limit shows in the bottom section of the F4 display. The 74 mph speed limit also is displayed on the driver console of the Class 180(Adelante). This started happening several releases back. I am now running x2727 on the EB_GWR route.

The displayed speed limit is, AFAIK, always the lowest overall one, of Route max speed, Train / Loco max speed, Posted max speed and signal-indicated max speed. Obviously, the loco / consist max peed in this case is lower than the current track speed limit.

Googling the Class 180, I found it should be allowed to go 125 MPH, which means that something´s indeed wrong here. What, I can just guess currently. It would be helpful if you could provide a ZIP containing the ENG and CON file used in the specific case.

Cheers, Markus

It is Ben Law's UKTS_7009_Class180 from UKTrainSim. The speed limits displayed properly in an earlier release, but I am not certain how far back.

I´m sorry, I personally have no account on UKTS. Also, I assume, this wouldn´t prvide the related .COM file.

I am not sure that is the problem. The same thing happens with a class 220 on the Dorset Coast V6 route and with a HST on the Bristol-Swansea route, although neither has an in-cab display of the speed limit like the class 180, but both are good for 125. I will try to get you the .eng & .con files.

The max displayed speed for a consist in OR is read from the con file MaxVelocity. The first figure is meters per second and for 125mph should be 55.88.

Thanks. It was the .con file. I'll have to check the other .con files.

Hi,
Surely the consist's MaxVelocity should only come into play when the ruling line speed is higher. The F4 Max Speed should indicate the maximum speed at which the train is allowed to travel - it'll be either the current line speed or the consist MaxVelocity, whichever is the lower.

The MaxVelocity values in a CON file are only used for AI Consist. For Player Consists it is calculated from the current lead loco's ENG file. As player consists can change over the course of an activity where as an AI's numbers remain constant.

The MaxVelocity numbers in a CON are calculated when the Consist is saved. Not all consist editors calculate the number. Some substitute the values of ( 40.000 1.000 ) which is what the freeware version of ConBuilder does but it also has a tool for the User to enter the values provided the User knows how to calculate them.

Although that is the case for MSTS, Open rails uses the MaxVelocity line to determine the max speed of a consist, even the player, and in the case of the player, this is what gets displayed in the track monitor as the consist Max Speed where this is lower than the track speed limit.

It is a brilliant feature of OR, that you can actually set the max speed of any train by adjusting the max velocity in the .con file.

I have been through all my UK consists and adjusted them to real world values, which is excellent when running BR steam\diesel era activities in particular. To not have consists traversing a route at crazy speeds.

Yes, Brilliant. Since all your Activities were designed with the MaxVelocity in the AI consists calculated the way the MSTS CE calculates them. So now the activities no longer run correctly.

Open rails was never designed to be 100% compatible with MSTS. It has different ways of doing things. Activities being a case in point. Most will work as intended, some do not and require further fiddling in the MSTS AE until OR gets its own AE. Open rails will always use the Maxvelocity line for MSTS AI consists, but where it goes after version 1 is released is not yet worked out.

Other things that are not the same as MSTS are the signalling system, the steam locomotive code, adhesion, couplings, and brake systems to name a few. The controls and key strokes that operate them are the same but OR now goes far beyond MSTS in what it can do. Yes, there are still bugs to iron out, but they are slowly being fixed, unlike MSTS which will never have any bug fixes.

Neyland,
Here is a portion of a CON file:
TrainCfg ( "576 test"
Serial ( 1 )
MaxVelocity ( 31.73984 0.04093 )
NextWagonUID ( 61 )
Durability ( 1 )
Engine (
UiD ( 0 )
EngineData ( gp30_up713 dekosoft_up_gp30 )

The MaxVelocity line in the gp30_up713 engine file at the lead is:
MaxVelocity ( 71mph )

What would you change the MaxVelocity line of the to?

[neyland]

My activities work fine. No idea about the gp30 not much interest in USA railroads sorry.

But the max speed of those locos i believe is 78mph (34.869 12)

But if the train that loco is hauling has a lower overall speed then i would adjust the max velocity of that consist accordingly.
