Hi Trainzers,

In this thread, I am attempting to find out if any other Trainzers are having issues with trains loading/unloading at andi06's AJS Invisible stations.

The reason I am doing this is to work out the extent of problems, as I believe there is a script issue involved that only andi06 can fix, as the main script file used by these stations is encrypted. (one of the reasons why I dislike script encryption)

The problems I am particularly interested in are ones where the train arrives at the station, but does not load/unload or has a delay of more than a few seconds before doing so. Also, in some situations, issues can crop up later in the hour, including buffer overflows.

When replying, please state the problem encountered, as well as which of the AJS Stations you are using. If you are unsure, open the route up in Surveyor then use the Find Object tool in the menus to find the station, then use the Get Object tool on the Buildings tab to check which one it is.

I also want to know which version (including build) you have when replying to this post.

Thankyou to all those who do read/reply to this post.

I'm just working on revision of the route Moscow-Maloyar, where i use AJS Invisible station 1T 3.5. In this moment there is more then 100 stations installed (the final number of the stations on the route will be much higher) and two of them don't work properly, train stop but don't load passengers.

Hello Shane,

Instead of typing it again, here's a link what I wrote about the subject january 24th this year.

I use 1T 3.4 and 2T 3.5. Problems encountered are rather long delays when loading/unloading, also I cant ever remember seeing the doors open on the carriages but not sure if I am meant to.

Thankyou to all who have replied.

It's a good sign to see that I'm not the only one who is having issues with these assets.

Something I have found during dealing with these assets is that they are inherently faulty for different reasons.

Hopefully andi06 can explain why there are so many issues with them.

Shane, this may not be relevant to your problems but I have sometimes noticed in the past that if there is a junction spline point within the station zone on the track attached to that station (ie anywhere between the outer edges of the green circles) that the behaviour of the station can sometimes be a bit unreliable. It can also affect AI control of the consist causing it to stop dead or take the wrong path. I try to avoid having any junctions in the zone and if possible I avoid any track spline points in the zone. This has sometimes cured my problems but it can be difficult to do if the layout involves a lot of junctions close together like around a large city centre station. Junctions on other tracks close by but not actually connected to that platform do not affect things, only the track connected matters.

I will have to check that, as most of my AJS stations are used at city centre stations or similar.

All the AJS stations have that problem for me in build 49922.

 

[devinclancy]

I have experienced the slow down but don't stop bug at the 4-track station. I have build 49922.

I was thinking it might have something to do with a high speed limit on the track and a train that couldn't slow down quickly enough, but I dropped the limit to 40 mph and saw the same thin

Hi Scottbe8,

Thankyou for your response.

It seems that the issues are fairly common with users of the AJS Invisible station assets. I am aware (from doing some validation on them) that some of them are faulty (missing attachent points etc).

Shane

 

[shaneturner12]

I've also had that happen - the advice I was given is to use a trackmark just before the station to slow it down.

Here you go:

Hmm, I've posted a question about this some time ago in the AJS Station Faq thread, but haven't seen a response from Andi yet.

On a little test board I noticed that on the first AJS station the AI train stops and behaves as expected, after that on all subsequent stations the train slows, stops, but immediately starts again without loading or unloading passengers. The Load command instruction is completely ignored in this situation and vanishes some moments after the train allready has left the station. Somebody mentioned to use both Load and Unload commands together to let it work, but that doesn't do the trick either over here.
I presume something in the script isn't compateble with ts12, allthought we're talking about buildin content here.

Thankyou oknotsen for your assistance - strangely enough, I have seen that issue as well in TS2009 SP4, as well as what I've described further up the thread.

I have problems with AJS stations, trains slow and stop for a moment but do not load /unload. I have done a lot of 'research' into the problem , but cannot find any logical answer.

Hi all,
here is a copy of a post of a couple of years ago that may shed some light on the subject:

"I have found that in 2010 the engines need a fairly high "max. deceleration" value to work with Andi06's stations.


Try this for a start:


remove all but two coaches from the consist, if this works increase the number of coaches untill the train fails to load.
This means you have to increase the max deceleration figure.
I found that a class 47 with 6 coaches needs something like a value of 220000 to stop in time for the station to work.
Remember, the train is trying to stop from 9-11 Mph in no more than about 10-15 meters! (in 2006 this was about 7 Mph).
Also consider the following post from Auran:






quote:






This thread will list information about how the AI operates. We'll start with speed control.


AI Drivers use the max accel, max decel to determine how fast to speed up and slow down. (Actually they also use the loco mass figure which is part of the loco file itself not the engine spec, plus the mass of all the other cars in the consist).


Top speed is determined by maxspeed (set in m/s so 40 = 40*60*60/1000 = 144kph).


We are talking here about the enginespec config files under the section Motor. you can view these by searching on Category/Train engine and display the config using View Config


The AI Drivers look at how fast they think they should be traveling and then set their throttle accordingly. So it will set at 50% in order to use half its power.


New code has been written for TS2009 to get AI drivers to drive more smoothly and to stop better at red lights (by looking down the track and determining when to start braking for a red light).


Also, in some previous versions of Trainz, engine specs used much lower settings due to different AI behaviour. TS2009 now looks at the engine spec as says, if Build Version <2.8 and max accel < 6,000 then multiple x 4.5. Also, if Build Version <2.8 and max decel < 10,000 then multiple x 4.5.


Here are some additional notes on this for those that would like a deeper explanation:


Isaac Newton said force equals mass times acceleration. Elementary mathematics thus gives us acceleration equals force divided by mass.


AI drivers use the "max-accel" and "max-decel" of all the locos in the consist to determine how much force to apply to the train. The mass is that of all the traincars in the consist.


The acceleration is thus the sum of all the 'max-accel' values for the locos, divided by the sum of all the 'mass' values for the traincars.


end quote.


I hope this point you in the right direction"

Hi
Thanks for your input Andyz, as I stated in my previous post I have done a lot of 'research' into this problem looking for any pointer to a solution including the points in Andyz's post. I think I have covered all possible eventualities that could cause this problem but I am still baffled.
When for instance there are two apparently identical stations, one operates correctly and one does not. If a AI passenger train fails to stop and load , if the train is then stopped manually and reversed to the platform it will then load. I am running TS12.
Any ideas or input on this subject would be welcome.

After running the route a little more i must change my opinion about invisible station(post #2). Much more stations don't work properly and now the new problem is showing, because suddenly trains don't recognize some stations anymore. So i was been forced to replaced them with K-station.

 

[DStyles]

Yeah, I've been having all kind of probs with andi06's stations. Work with some locos, not others. Work with some rolling stock, not others. Sometimes speed limit helps, sometimes it doesn't. Looking for alternatives now... How are those K-stations? Do they have passenger animations?

edit: tested both DMT invisible stations and the K-stations. both seem serviceable. Going to go with DMT (scottish). Wasted enough time trying to get those AJS stations to work with my various trains

 

[Scottbe8]

This thread has been dead for about a year. Quick question, though, are you running on 49922 or 58414?
