Hi Goku,

I am using version 0.6911 and I see a problem where the TrNode for the crossover in Romans YTracks slip switches is missing when the slip is placed. This causes a problem with signals and trains.

No TrNode means trains will not 'see' another train on the intersecting track path.
Reference here to the Steam4Me article I authored years ago.
Here >>>===> http://msts.steam4me.../diamond_X.html
Could you have a look at this as I am rebuilding the Philadelphia Terminal Zone Zoo Interlocking on the PRR-East Region Route that has many slips in the area.

Specifically the Crossover section that causes the missing TrNode is Y1tDblSlip190Xover_.s
Here is the GLOBAL/TSection.dat code block for the crossover shape.
TrackShape ( 31349
 FileName ( Y1tDblSlip190Xover_.s )
 NumPaths ( 2 )
 ClearanceDist ( 32 )
 SectionIdx ( 1 0 0 0 0 32672 )
 SectionIdx ( 1 0.581 0 0.0322 -6.3402 32672 )
 CrossoverShape ( )
 XoverPts ( 1 
  XoverPt ( 0 0 5.2616 )
 )
)


Thank you for your attention. Your editor is behaving beautifully, getting to be a real joy to work with.

regards,
vince

Indeed there is something wrong. Will be fixed in the future.

But, now you can easily overcome this:

Hi Goku,

Thanks but I'd prefer not to make a temporary fix as it will be some time yet before I get around to actually running trains here and so will wait for your fix.
Also there is the fact that there is no properly sized crossover that will correctly tie into the double slip tracks.
There is another method I've tried . . . Use MSRE. It does put the crossover node in correctly but waiting over a minute for a save to complete and also the intermittent crashing during a MSRE save which just means more recovery work.
I'll stay with TSRE and update when a fix is available.

regards,
vince

Worst case, you could do the fake junction node trick using hazards or speedposts...

But it is not temporary fix. TSRE has support for placing crossover points, but it looks like in some cases it doesn't work properly. But if you add to TDB the crossover shape first, it always work.
When I fix this issue, you will be still forced to remove and add to TDB the "broken" shapes.

Of course you can wait. It's your choice.

I'm afraid that's not always so.
I use UKFS, and always put in the cross-shape of slips first, it's not actually possible otherwise as the actual slip tongues are placed withing the cross-over shape, they do not connect with the approaching tracks.
Yet on both the single and double slip shown here, the cross-over node is missing. There's quite a few more like that. It's pretty much touch-and-go whether the cross-over point is added or not.

I mean, the shape can't be connected to other shapes that are already in TDB.
Look at my last picture.

Not possible to do using UKFS if you have two or more adjacent slips as these connect to each other - you can place one slip 'isolated' but any slips connecting to this one (e.g. when crossing multiple tracks) cannot be placed 'isolated' in such a way.
Please keep that in mind when creating a proper solution.

It is possible. You don't understand me. Look at the image tutorial again.

I tried that but could not get the sections to connect. Exclusively using Romans Y-Track sections.

So right now my solution is to use MSRE. I just select then de-select the crossover part and then save.
Takes OVER an minute to save PRR-East TDB which is annoying but it has worked flawlessly so far.http://www.elvastower.com/forums/public/style_emoticons/default/sweatingbullets.gif

Goku, I think this has something to do with the physical dimensions of the crossover section.
I see very small angle crossover shapes exhibit the same problem while large crossover section have no problem.

vince
