how to get the pantograph status?

Now, we can press P or CTRL+P to up or down the pantograph.
But I cannot how to get the pantograph status from animated object document.
I want to animation relate by pantograph's status.
How to get the status (up/down) of pantograph?
Please teach me.

That's not actually currently plumbed into anything except the train plugin interface, and in short is waiting for the whole pantograph feature set to be implemented
The basic idea behind adding headlights, wipers etc. keyconfigs even when the features weren't already present, is that it provides a placeholder for when they actually get added in the first place.

I've got a mostly feature complete branch for this from last year, but it got a little over-complex....
(yes, the whole switchable power supply types was a specific request from someone who currently uses an insane beacon set to do that)

It's one of the *many* things needing work at some stage soon.

Oh! I understand!
Each pantograph car's electric data will get enable is very difficult.
I will wait to enable this, or use BVEC_ATS or S520's DLL.
Thank you very much for answer!
