Speed Limit changes

[rlkimbal]

When the speed limit goes from a lower speed to a higher speed limit, the new speed limit does not show until the end of the train leaves the lower speed limit track. This is correct. When the speed limit goes from a higher speed limit to a lower speed limit, however the new lower speed limit should apply as soon as the head of the train enters the lower speed limit track. OR is not doing this. The new speed limit does not show until the entire train is in the new speed limit track. This is not correct. I am running version X2049 on Austin Yoder's Horseshoe Curve route.

Sorry, Dick, but it is correct.

The reduced speed limit does not have a black bar pop-up.
It is up to you, the engineer, to reduce your speed before arriving at the location where that reduced limit commences.

The pop-up that occurs when a speed limit increases is the OR equivalent of an in-cab length counter.
(The only sim which simulates the real thing at this time is Run 8.)

I am not sure what you mean about the "black bar pop-up". I am talking about the F5 Heads-up display.

The F5 display won't give you that information.

When the OR start menu opens up, click on Options.
When that menu opens, click on the first tab - General.
Make sure that there is no tick (check-mark) in the box next to "suppress control confirmations".

That will then allow you to receive the "speed may be increased" message (along with other messages relating to the use of the controls) in the form of a thin black bar with white writing that is displayed for a few seconds and then fades.

But there is no automatic control and no similar message to warn you to reduce speed.
That's up to you...either watching for line-side signs or using the F4 monitor.

i think this is what you mean.....


5.5:Permanent Speed Signs

Permanent speed restriction signs will be placed in advance of permanent speed restrictions. Numbers on the face of these signs indicate the highest speed permitted over the limits of the restriction.

Two Sets of Numbers

When two sets of numbers are shown, the greater number governs trains consisting entirely of passenger equipment. The lesser number governs all other trains.

Resume Speed Signs

A permanent resume speed sign or a speed sign showing a higher speed will be placed at the end of each restriction.

Crew members must not exceed the speed shown on each permanent speed restriction sign until the rear of the train:

Has passed a permanent resume speed sign or a sign showing a higher speed.
or
Has cleared the limits of the restriction.

[Diagram A]

Application:

The location of permanent speed signs are:

2500 feet ahead of the restriction (Arrow-shaped signs).
2 miles ahead of the restriction (Square or rectangular signs).

My mistake, I meant the F4 Track Monitor display. The third line is the speed limit and affects the color of the display.

If you have the F4 window opened upcoming track speed limits are displayed in the fourth section along with signal aspects which gives you plenty of warning and time to slow down if required. The new lower limit does apply as soon as the head end passes the limit sign.

[rlkimbal]

Yes, this is what I was referring to. The lower speed limit is not displayed in the 3rd line until the entire train is in the new lower speed limit track. not when the head end enters the new lower limits.

I have not run the Horseshoe so cannot comment on that. I have however run a lot of routes and in all cases the lower speed limit is applied when the head end passes the lower limit marker.

[rlkimbal]

It is not noticeable with a short passenger train, but with a 75 car BNSF intermodal train is is very evident.
