Trainz2012 and the "dreaded" 40mph blanket limit

[chopperaddict]

Hi

Having recently installed 2012 after using 2006 a few years back, I find that all my trains run at a max of 40mph. I have tried the speed option in commands - no change, and speed boards around my large layout - they all still run at 40mph - PERIOD

Anyone tell me how to change these ?

Cheers
Ian

Just a wild guess, are the speed boards above the 40mph? Sometimes, enginespec glitches can also cause strange speed restrictions, such as lashing up different types of locomotives.

In addition to the above, have you patched Trainz 12 at all?

Also, is your route signaled?

Hi guys
In order of reply :-
1 - I have a speed board of 60MPH immediately after the train leaves the station
2 - I am running the very latest build 58414 direct from the downloads I purchased.
3 - Yep, fully signaled, and they all work !!!

It may be worth checking that it is a 60MPH sign, and not a 60KPH sign, as 60KPH is ~37MPH.

if I am driving the PRR K4 off of the download station I got well when ever it hits 119 it keeps speeding BUT just when it is about to hit 120 it glitches and goes back to 95 in a click of a second than after it slows down to 95 it says my reverser that is at 75% is having wheelslip then it speeds up and does the same thing over and over is there a way to fix this its in TRS12 BTW

I would suggest that you check your signaling as I have no problems getting my AI drivers up to 60 and 70 mph on my current route.

What I have found is the AI drivers will slow down for junctions and crossovers especially if they are signaled with the new scripted signals such as the Searchlights from Jointed Rail. AI drivers will also slow down if a junction is not set in their favor even if the junction is miles away. This is prototypical because in reality they would be driving at half speed as they prepare to stop, and would be "riding the yellows" as they call it. You might want to check that your junctions are set in their favor so there is no reason to slow down.

For signaling I suggest that you read through Chuck Brite's tutorial on track laying. He has some great examples on how to do this.

As far as my signaling I use the following forumula:

Where track goes from single to double:

Type 06 facing towards the signal track.

Type 04's (absolute stop) facing towards the double track.

Type 05's (permissive signals - ones with little signs under the head) every 1/2 mile or so, depending upon the length and speed of your trains. For faster frequent trains, such as on a commuter route, you may want to place them closer. For longer freights, you may want to place them farther away. I usually use the 3000T US coal train as my sliding ruler and place signal close to one end of the train. This ensures a consistent spacing.

With crossovers, I use type 06s and type 04s with the type 04s on the straight lines and type 06s at the switch. With crossovers, I suggest using a junction-controller or linker so that the junction levers move together. This will ensure consistent speed on the crossovers so there is no reason for the AI to stop to change a junction.

I also suggest using direction markers if possible to ensure that they are not going against the signals on double track. If they do this, they will operate at 30-40 mph, or at the last posted speed for that direction.

Following your answers above, chopperaddict, am beginning to think that the main possible culprits are now likely to be:
1. A 60 kph speed board instead of a 60 mph one, as Shane suggests
2. A faulty switch along your route that needs to be replaced
3. That, maybe, your track ahead forms a LOOP, in which case the AI will proceed with caution and rarely attain maximum allowable speeds

My suggestion is to drive the route yourself manually and see what obstacles present themselves along the way.
In particular, look for junctions set against you as JCitron suggests and observe the state of the signals ahead. (Sometimes map view will give you a better perspective on current signal states.)

All of this presumes that you are not driving a locomotive where the engine spec prohibits speeds greater than 40 mph!
Good luck in tracking this miscreant down!

I have tried all the above with little success - UNTIL I uses different set of speed control assets, and then, it all started to work as i should. The ones that work are those that are just small round white boards with red speeds on them. Problem is there is only a small selection of them in 2012, roughly 10, 15, 50, 60, 120mph, which is a bit limiting, but at least they do not all creep around at 40mph any more.

You might also want to try Speed Limit Sign xxx = Where xxx equals the speed limit. There's a slew of them from 15 mph right up to 120 mph. They're tiny white signs that look pretty good.

You're using the British speedboards. You might also want to try Speed B xxx mph, which also has left-hand variants, for 010 to (I think) 125 mph in 5 mph increments.
