Pantograph squat through tunnels

[Fender849]

Hi all,
I recall reading a forum topic some time ago, regarding auto lowering or squatting of the pantograph during the trains progess through a tunnel. Of course, I cannot find that topic now, but does anyone recall the outcome ? I would imagine it only possible by scripting the pantograph in conjunction with a trigger at tunnel entry and exit, but it would be nice to know if any such system does exist before I spend the next few months trying to invent something. All responses appreciated and welcome.
Cheers, Fender

Hi Itareus,
No. not that thread. I did a search for "Pantograph" , but not in any of those - I just cannot recall which heading the origional post was.
Thanks anyway.
Cheers,
Fender
