Portal question.

might be back?
Just wondering. When you have a portal set up to emit trains every half an hour, does the timer restart every time you load the session, or is unaffected by saving, and loading it later?
 
Portals stop emitting trains

I have a different question regarding portals: I am trying to write a session for Phil Skene's PortOgden&Northern v2a, the most recent one. I use the Central Portal Control rule for the AI trains, the emission intervals are ten to 15 minutes, but after some time the portals stop emitting. In the JetLog I find lots of entries like this:

SCRIPT> PortalTunnel.EmitNewVehicle> Vehicle.Reposition failed - will retry

JetLog and session can be made available on request

I shall retry and program the portals directly instead of using CPC.

I use central portal control and in it you specify the number of consists. I found that when that number is reached all portals stop emitting. If that is the problem set the number higher rembering that a single parked wagon counts as one.

I have just discovered a Portal problem I have not seen discussed. I am emitting a train with 11 Auto Racks, all in a string along with at lest 20 boxcars. When the train is emmiting, the tenth Auto Rack car to appear on the track promptly derails. There is then a contagen to the front of the train and all cars are on the ground. The train has yet to become active.

Has anyone seen this problem before?

Two questions David...

Which portal are you using?

Is there a junction or signal (or maybe another track object) within a train length of the portal exit?

Maggs Rerail Portal. This happens whether the Auto Racks are at the front of the train or at the rear of the train. Watching the emit process, you can see the tenth car jump off the track almost as soon as it is created at the back of the Portal Track. I think what is happening, the cars are so long that by the tenth car, the back wheels are not on the tracks when the car is created. As soon as the derail occurs, starting at the back, the train stops and no more cars are emitted. THis portal successfully emits other trains of this size that do not contain 11 Auto Racks, so I don't think that the track in front of the portal is an issue.

David,

My first suggestion would be to try the built in Portal,<kuid:-3:10192> in place of the Maggs portal (replacing one for the other). If the problem still occurs then it must be a fundamental problem with portals (or the specific vehicle assets) and not the Maggs Portal. This will at least eliminate one possible cause.

Depending on the results of the above I would try replacing the Auto Racks with cars of an exactly equal length (wheelbase) if you can find any, and then with cars of a greater wheelbase and see what happens.

Hi David - You can add track to the rear of the portal to extend it. I have seen another post about this problem but don't know how to include links to other threads yet.

Chris,
I was able to get the train to emit when I placed 2 boxcars between each of the 11 Auto Racks. However, this would require some extensive switching once the train arrives at the yard.

Trev,
Also, I would add a piece of track to the back end of the portal, but it is hanging out in space and there is no way to make that happen.

My solution is to place the Auto Racks on a siding and have the emitted train pick them up on its way to the main yard.

When trying to create sessions using a built in route on which you can not make changes, one must be deceptively and somewhat obtusely clever. :cool:

Thanks for your suggestions.

make ur track long enought fo rthe portal to kick it out, at my portals i have at lest 1/2 of track in front of it before it see a signal or switch
 
David,

.....I was able to get the train to emit when I placed 2 boxcars between each of the 11 Auto Racks........

Looks like an asset problem then, although it would be interesting to try replacing the portal with another variant just to be sure.

..........using a built in route on which you can not make changes..........

I'm sure you know this (but just to clarify for newer users who might read this thread) - you can always "Clone" an existing route to make your own version and then modify it. This does of course raise copyright issues etc. if you wish to release the route / session.

..........one must be deceptively and somewhat obtusely clever. :cool: ..........

You will go far in Politics !!!! :hehe:

Regards

I tryed what you did and i got the same derail....mmmmmm

CT,

Trev has the answer - put a piece of track on the back end of the portal so the longer cars will have track to set their wheels on. I just can't do it in one particular instance bcause the portal is hanging way out into space.\ and there is no other way to place this particular portal.

Hi David does that "one particular instance" by any chance have the portal inside terrain/building etc?.
ie If the portal is out of view; inside something, then have you considered adding rear track but dragging it down & burying it?. This might give sufficient length, yet keep that rear section out of view?.
Not sure if the train can pull it up such a steep incline within a portal 'though? :o
 
Noel,

There is no other way to place the portal in this instance other than to hang it over the edge. The only part of the portal on the tera-firma is the entrance circle thingy. I am creating a session for a built-in route for the Big Session Contest. The original route can not be modified. There is no other way to place the portal than to hang it over the edge. I have a working solution and have moved on.

By the way, I have buried portals on other routes and have had no problem with them working. Thanks for your suggestions.

Hi David,

There are many many backdrops available, & if one doesn't suit/fit this situation, perhaps one could be tailor-made?. Some backdrops are really small/short affairs, that you fit at the rear of the gap between two scenery objects such as buildings etc. Perhaps a cluster of trees, with tree backdrop splines. Dave Drake made some excellent ones for the DHR route.
They had 3D trees & foliage attached both in front & behind the 2D plain; which was of the same foliage.

But I guess you've already been down this path. I mention it for the benefit of anyone so interested. :wave:
