Need help making junctions that won't derail trains

I've created a rather simple layout that I've been working on & decided to add a junction to another line just to test my building skills...anyhow my consist keeps derailing when passing through the junction.I figure t hat it's because my track either isn't long enough between the junction point & the point at which it straightens out to accomodate the wheelbase of the cars or doesn't go out far enough before making the turn....are there any good junction making tutorials available?
 
Are you using the standard (automatic) junctions, or fixed junctions?
I find that is track is laid over uneven terrain, and the splines are white, not yellow, track may be at different elevations, causing derailment.
If this happens, just click the change height button in advanced track, then click the spline once. It should turn yellow, even if you don't raise or lower the height.

The problem with derailments lies more in the train/consist not being able to navigate the "S" curve portion of the junction,it could be due to the fact that I may be trying to straighten the curve out too soon & the long wheelbase of the cars in my consist simply can't navigate the curve.

I'll take a look at the tute that Itareus posted & see what I can find out

Not very likely.... the appearance of trains running on the tracks is an "illusion" (bit hard to get you head round this, especially if you come from a model railroading background). For example, you can happily run 2' gauge trainz on standard gauge track, or buildings on roads in Trainz, if you really want to!

Have a look in Surveyor settings for something like "Auto Junction Placement" and turn this on. This might help your problem. (sorry but I'm not on my Trainz machine at the moment so can't give you exact details of where to look for this setting).

Still worth checking out those tutorials though.....

Ok,I think I may have figured things out just a bit after creating a new route in TRS04 as I've gotten the junction from the turntable to the mainline functioning but in trainz version 1 it may still be due to the wheelbase of the cars(using a UK loco & cars on that route) but I'll keep playing with it til I get it right.
 
Mikeinva get that tute and read it. Just staring out you will need it and it will be come your bible for track laying.

I'll make a printout of it ASAP.Speaking of junctions now I'm having problems on the highland valley scenario,my consist keeps derailing at the junction just south of the Robbins station on the return run...I've run the scenario twice now & can't figure out why since the switch should be set to either one position or the other but not in between which is the only thing I can think of that would cause a derailment even at low speed.
 
Check the lay of the points. I do remember being very confused in Trainz 1 because trains would derail when trailing through incorrectly aligned points! This never happens in the real world because the switchblades are forcibly moved by the wheel flanges; points rodding and mechanism gets mangled but the train doesn't usually derail. By the time 04 came out this little 'feature' had been corrected.

It is possible that these points lie the opposite way to the indicator arrow. I do have a vague recollection of a problem like this somewhere in the dim distant past.

In one of the previous station stops...I think it's either strmont or robbins you have to wait for another consist using the same line to pass so if the points are out of line it may be from that train crossing the junction...however if that's the case you should get a notice to stop & adjust the junction but do not.

Next time I play that scenario I'll check the map to see what line the approaching consist is using when it hits that junction.

Is this the "08 - Highland Valley" scenario? When I explored it some years ago I made these notes: On the return trip, after stopping at Robbins station and then waiting for the AI train to pass, junction Robbins North changes to left (as it should) but then back to right. It is locked. The Robbins South junction is also locked. Attempting to traverse Robbins North with it set in the wrong direction results in a derailment even at 1mph. It is therefore impossible to continue beyond this point.

The other Highland Valley sessions and scenarios all work ok. "07 - Highland Valley Coal" is a particularly clever puzzle, very enjoyable.

The only time trains should derail is when track is drasticly and radicly wrong, rollercoaster grades, or is physically disconnected (a gap in the track where track splines are not joined).

This is not real life, it is a simulator.

And if you have derailment realisim turned on, turning the realisim off might cure all your headaches. That is, unless you want all the real life physics and derailments spoiling your enjoyment of the gaming.

I have well over 300+ miles of track, some of it tight trolley turns, and complex tight junctions, and I have very few derailments.

In Trainz I can run a TGV or Jet Sled at 867mph through wrongly alligned switch points, around a 10m radius curve, and even a DD40X wont derail, downhill or uphill with a 20,000 ton train in tow, with DPU helpers shoving on the rear.

It's the Highland Valley scenario in TRS 04....I'm running it via trainz complete but that's the only part of the program that would install due to my video card not meeting the pixel shader requirements.
 
I have never known a train to derail due to wrongly aligned points. Even when derailments are turned on, I don't have any derailments for that reason.
The one thing that does derail my trainz, is when track has a "step' at a junction, or is otherwise misaligned.

A while back, I was laying track in TS2006, and found the train derailing at a specific location. There was no junction, but I found that the spline was white, and not yellow. The cure was to delete the section of track, and re-lay. I have not had that happen in TS2009 though.

I noticed that when trying to solve my driver issue using a route I made in TRS06 & had to delete the entire route,try another station type & build again making certain to line up the rails on both the station & outgoing/incoming track.

John259 posted a while back about problems he experienced in the Highland Valley scenario with the junctions being locked & therefore unchangable....has anyone tried going into surveyor & correcting this problem?
 
Hello everybody,

I'm currently busy with a project containing more than 2000 junctions.

I have read the excellent tutorials from Chuck Brite.


Nevertheless, some junctions are giving me some problems.

When a single locomotive runs over the track - I have no derailments.

Running locomotive+wagons gives me several derailments.

When you have a look at the picture - one of my junction problem is the one at junction 52.

junctions 52.jpg


I'm using automatic junctions and I'm frequently using the straighten tool. In this case it doesn't help.
With most of my junctions, the trains+wagons must pass at a reduced speed ( 50km/h = 31 m/h ).

Does anyone have some ideas how to resolve this problem?

Thank you

Best regards

Kurt :wave:
 
Looking at the screenie, I noticed Junction 52 is turned away from the approaching train. It is showing alignment to the right for the outermost leg of thr yard, but the train is comming from the left leg of this turnout. This could be the of the issue with derailments at this turnout.
 
Hello maruffijd,

Thank you for your reply.

My picture in answer #17 is perhaps not a good one.

Here is another : When a train leaves just in front of junction 2004 I have no derailment, passing junction 58 no derailment. Going from junction 58 to junction 52, just in front junction 52 derailment.

I have run long wheelbase locos at high speed around rediculously tight 10m radius curves and never have derailments.

I see some switch laying errors, with improper straightened sections.

A switch should look like this: -----o-o<==========

With the two oo's overlapping like a sideways figure 8 ... and the short track in between the oo's is straightened.

Derailments are caused by disconnected track.

Or derailment realism turned on.
